It is important in maintaining the colloidal osmotic pressure and transporting large organic molecules.Retinol-Binding Proteins: Proteins which bind with RETINOL. The retinol-binding protein found in plasma has an alpha-1 mobility on electrophoresis and a molecular weight of about 21 kDa. The retinol-protein complex (MW=80-90 kDa) circulates in plasma in the form of a protein-protein complex with prealbumin. The retinol-binding protein found in tissue has a molecular weight of 14 kDa and carries retinol as a non-covalently-bound ligand.Retinol-Binding Proteins, Plasma: Retinol binding proteins that circulate in the PLASMA. They are members of the lipocalin family of proteins and play a role in the transport of RETINOL from the LIVER to the peripheral tissues. The proteins are usually found in association with TRANSTHYRETIN.Protein-Energy Malnutrition: The lack of sufficient energy or protein to meet the body's metabolic demands, as a result of either an inadequate dietary intake of protein, intake of poor quality dietary protein, increased demands due to disease, or increased nutrient losses.Amyloidosis: A group of sporadic, familial and/or inherited, degenerative, and infectious disease processes, linked by the common theme of abnormal protein folding and deposition of AMYLOID. As the amyloid deposits enlarge they displace normal tissue structures, causing disruption of function. Various signs and symptoms depend on the location and size of the deposits.Rats, Inbred BUFNutritional Status: State of the body in relation to the consumption and utilization of nutrients.Blood Protein Electrophoresis: Electrophoresis applied to BLOOD PROTEINS.Thyroxine: The major hormone derived from the thyroid gland. Thyroxine is synthesized via the iodination of tyrosines (MONOIODOTYROSINE) and the coupling of iodotyrosines (DIIODOTYROSINE) in the THYROGLOBULIN. Thyroxine is released from thyroglobulin by proteolysis and secreted into the blood. Thyroxine is peripherally deiodinated to form TRIIODOTHYRONINE which exerts a broad spectrum of stimulatory effects on cell metabolism.Norethandrolone: A synthetic hormone with anabolic and androgenic properties and moderate progestational activity.Vitamin A: Retinol and derivatives of retinol that play an essential role in metabolic functioning of the retina, the growth of and differentiation of epithelial tissue, the growth of bone, reproduction, and the immune response. Dietary vitamin A is derived from a variety of CAROTENOIDS found in plants. It is enriched in the liver, egg yolks, and the fat component of dairy products.Malnutrition: An imbalanced nutritional status resulted from insufficient intake of nutrients to meet normal physiological requirement.Blood Proteins: Proteins that are present in blood serum, including SERUM ALBUMIN; BLOOD COAGULATION FACTORS; and many other types of proteins.Hepatic Insufficiency: Conditions in which the LIVER functions fall below the normal ranges. Severe hepatic insufficiency may cause LIVER FAILURE or DEATH.

NUTRITION SURVEYS may be used in making the assessment.Kwashiorkor: A syndrome produced by severe protein deficiency, characterized by retarded growth, changes in skin and hair pigment, edema, and pathologic changes in the liver, including fatty infiltration, necrosis, and fibrosis. The word is a local name in Gold Coast, Africa, meaning "displaced child". Although first reported from Africa, kwashiorkor is now known throughout the world, but mainly in the tropics and subtropics. It is considered to be related to marasmus. (From Dorland, 27th ed)Transferrin: An iron-binding beta1-globulin that is synthesized in the LIVER and secreted into the blood. It plays a central role in the transport of IRON throughout the circulation. A variety of transferrin isoforms exist in humans, including some that are considered markers for specific disease states.Immunoelectrophoresis: A technique that combines protein electrophoresis and double immunodiffusion. In this procedure proteins are first separated by gel electrophoresis (usually agarose), then made visible by immunodiffusion of specific antibodies. A distinct elliptical precipitin arc results for each protein detectable by the antisera.Nephelometry and Turbidimetry: Chemical analysis based on the phenomenon whereby light, passing through a medium with dispersed particles of a different refractive index from that of the medium, is attenuated in intensity by scattering. In turbidimetry, the intensity of light transmitted through the medium, the unscattered light, is measured. In nephelometry, the intensity of the scattered light is measured, usually, but not necessarily, at right angles to the incident light beam.Thymus Hormones: Humoral factors secreted by the thymus gland. They participate in the development of the lymphoid system and the maturation of the cellular immune response.Nutrition Disorders: Disorders caused by nutritional imbalance, either overnutrition or undernutrition.Amyloid: A fibrous protein complex that consists of proteins folded into a specific cross beta-pleated sheet structure. This fibrillar structure has been found as an alternative folding pattern for a variety of functional proteins. Deposits of amyloid in the form of AMYLOID PLAQUES are associated with a variety of degenerative diseases. The amyloid structure has also been found in a number of functional proteins that are unrelated to disease.CeruloplasminEnteral Nutrition: Nutritional support given via the alimentary canal or any route connected to the gastrointestinal system (i.e., the enteral route).

Inhibition by lead of production and secretion of transthyretin in the choroid plexus: its relation to thyroxine transport at blood-CSF barrier. (1/852)

Long-term, low-dose Pb exposure in rats is associated with a significant decrease in transthyretin (TTR) concentrations in the CSF. Since CSF TTR, a primary carrier of thyroxine in brain, is produced and secreted by the choroid plexus, in vitro studies were conducted to test whether Pb exposure interferes with TTR production and/or secretion by the choroid plexus, leading to an impaired thyroxine transport at the blood-CSF barrier. Newly synthesized TTR molecules in the cultured choroidal epithelial cells were pulse-labeled with [35S]methionine. [35S]TTR in the cell lysates and culture media was immunoprecipitated and separated by SDS-PAGE, and quantitated by autoradiography and liquid scintillation counting. Pb treatment did not significantly alter the protein concentrations in the culture, but inhibited the synthesis of total [35S]TTR (cells + media), particularly during the later chase phase. Two-way ANOVA of the chase phase revealed that Pb exposure (30 microM) significantly suppressed the rate of secretion of [35S]TTR compared to the controls (p < 0.05). Accordingly, Pb treatment caused a retention of [35S]TTR by the cells. In a two-chamber transport system with a monolayer of epithelial barrier, Pb exposure (30 microM) reduced the initial release rate constant (kr) of [125I]T4 from the cell monolayer to the culture media and impeded the transepithelial transport of [125I]T4 from the basal to apical side of epithelial cells by 27%. Taken together, these in vitro data suggest that sequestration of Pb in the choroid plexus hinders the production and secretion of TTR by this tissue. Consequently, this may alter the transport of thyroxine across this blood-CSF barrier.  (+info)

Subtilisin-like proprotein convertases, PACE4 and PC8, as well as furin, are endogenous proalbumin convertases in HepG2 cells. (2/852)

Serum albumin is synthesized as a larger precursor form, proalbumin, which undergoes proteolytic processing at a dibasic site by a hepatic proprotein convertase within the secretory pathway to generate the mature form. Although furin, a member of the subtilisin-like proprotein convertase (SPC) family, was thought to be the only candidate hepatic convertase for proalbumin, SPC family members other than furin were recently suggested to also be involved in proalbumin processing. This study was designed to identify the endogenous proprotein convertases involved in proalbumin processing. Since human hepatoma HepG2 cells are highly differentiated and produce major plasma proteins, this cell line was used as a model for hepatocytes. Northern blot analysis revealed that PACE4, furin and PC8 of the SPC family were expressed in HepG2 cells as well as in the liver. Ribonuclease protection assay showed that PACE4A-II mRNA is the major transcript in HepG2 cells among the PACE4 isoforms. The coexpression studies showed that furin, PACE4A-II and PC8 were all able to convert proalbumin to albumin correctly. To elucidate the roles of these endogenous SPC family members in proalbumin processing, the antisense RNA for PACE4, furin and PC8 was stably expressed in HepG2 cells, respectively. The expression of each antisense RNA resulted in approximately 30% inhibition of endogenous proalbumin processing. We therefore concluded that PACE4 and PC8, as well as furin, are involved in the processing of proalbumin in HepG2 cells, and that these SPC family members are functionally redundant in this processing.  (+info)

Transthyretin Leu12Pro is associated with systemic, neuropathic and leptomeningeal amyloidosis. (3/852)

We report a middle-aged woman with a novel transthyretin (TTR) variant, Leu12Pro. She had extensive amyloid deposition in the leptomeninges and liver as well as the involvement of the heart and peripheral nervous system which characterizes familial amyloid polyneuropathy caused by variant TTR. Clinical features attributed to her leptomeningeal amyloid included radiculopathy, central hypoventilation, recurrent subarachnoid haemorrhage, depression, seizures and periods of decreased consciousness. MRI showed a marked enhancement throughout her meninges and ependyma, and TTR amyloid deposition was confirmed by meningeal biopsy. The simultaneous presence of extensive visceral amyloid and clinically significant deposits affecting both the peripheral and central nervous system extends the spectrum of amyloid-related disease associated with TTR mutations. The unusual association of severe peripheral neuropathy with symptoms of leptomeningeal amyloid indicates that leptomeningeal amyloidosis should be considered part of the syndrome of TTR-related familial amyloid polyneuropathy.  (+info)

Exposure of cryptic epitopes on transthyretin only in amyloid and in amyloidogenic mutants. (4/852)

The structural requirements for generation of amyloid from the plasma protein transthyretin (TTR) are not known, although it is assumed that TTR is partly misfolded in amyloid. In a search for structural determinants important for amyloid formation, we generated a TTR mutant with high potential to form amyloid. We demonstrated that the mutant represents an intermediate in a series of conformational changes leading to amyloid. Two monoclonal antibodies were generated against this mutant; each displayed affinity to ex vivo TTR and TTR mutants with amyloidogenic folding but not to wild-type TTR or mutants exhibiting the wild-type fold. Two cryptic epitopes were mapped to a domain of TTR, where most mutations associated with amyloidosis occur and which we propose is displaced at the initial phase of amyloid formation, opening up new surfaces necessary for autoaggregation of TTR monomers. The results provide direct biochemical evidence for structural changes in an amyloidogenic intermediate of TTR.  (+info)

Potential mechanisms of thyroid disruption in humans: interaction of organochlorine compounds with thyroid receptor, transthyretin, and thyroid-binding globulin. (5/852)

Organochlorine compounds, particularly polychlorinated biphenyls (PCBs), alter serum thyroid hormone levels in humans. Hydroxylated organochlorines have relatively high affinities for the serum transport protein transthyretin, but the ability of these compounds to interact with the human thyroid receptor is unknown. Using a baculovirus expression system in insect cells (Sf9 cells), we produced recombinant human thyroid receptor ss (hTRss). In competitive binding experiments, the recombinant receptor had the expected relative affinity for thyroid hormones and their analogs. In competitive inhibition experiments with PCBs, hydroxylated PCBs (OH-PCBs), DDT and its metabolites, and several organochlorine herbicides, only the OH-PCBs competed for binding. The affinity of hTRss for OH-PCBs was 10,000-fold lower (Ki = 20-50 microM) than its affinity for thyroid hormone (3,3',5-triiodothyronine, T3; Ki = 10 nM). Because their relative affinity for the receptor was low, we tested the ability of OH-PCBs to interact with the serum transport proteins--transthyretin and thyroid-binding globulin (TBG). With the exception of one compound, the OH-PCBs had the same affinity (Ki = 10-80 nM) for transthyretin as thyroid hormone (thyroxine; T4). Only two of the OH-PCBs bound TBG (Ki = 3-7 microM), but with a 100-fold lower affinity than T4. Hydroxylated PCBs have relatively low affinities for the human thyroid receptor in vitro, but they have a thyroid hormonelike affinity for the serum transport protein transthyretin. Based on these results, OH-PCBs in vivo are more likely to compete for binding to serum transport proteins than for binding to the thyroid receptor.  (+info)

Biochemical but not clinical vitamin A deficiency results from mutations in the gene for retinol binding protein. (6/852)

BACKGROUND: Two German sisters aged 14 and 17 y were admitted to the Tubingen eye hospital with a history of night blindness. In both siblings, plasma retinol binding protein (RBP) concentrations were below the limit of detection (<0.6 micromol/L) and plasma retinol concentrations were extremely low (0.19 micromol/L). Interestingly, intestinal absorption of retinyl esters was normal. In addition, other factors associated with low retinol concentrations (eg, low plasma transthyretin or zinc concentrations or mutations in the transthyretin gene) were not present. Neither sibling had a history of systemic disease. OBJECTIVE: Our aim was to investigate the cause of the retinol deficiency in these 2 siblings. DESIGN: The 2 siblings and their mother were examined clinically, including administration of the relative-dose-response test, DNA sequencing of the RBP gene, and routine laboratory testing. RESULTS: Genomic DNA sequence analysis revealed 2 point mutations in the RBP gene: a T-to-A substitution at nucleotide 1282 of exon 3 and a G-to-A substitution at nucleotide 1549 of exon 4. These mutations resulted in amino acid substitutions of asparagine for isoleucine at position 41 (Ile41-->Asn) and of aspartate for glycine at position 74 (Gly74-->Asp). Sequence analysis of cloned polymerase chain reaction products spanning exons 3 and 4 showed that these mutations were localized on different alleles. The genetic defect induced severe biochemical vitamin A deficiency but only mild clinical symptoms (night blindness and a modest retinal dystrophy without effects on growth). CONCLUSIONS: We conclude that the cellular supply of vitamin A to target tissues might be bypassed in these siblings via circulating retinyl esters, beta-carotene, or retinoic acid, thereby maintaining the health of peripheral tissues.  (+info)

1H-NMR structural studies of a cystine-linked peptide containing residues 71-93 of transthyretin and effects of a Ser84 substitution implicated in familial amyloidotic polyneuropathy. (7/852)

The Ile-->Ser84 substitution in the thyroid hormone transport protein transthyretin is one of over 50 variations found to be associated with familial amyloid polyneuropathy, a hereditary type of lethal amyloidosis. Using a peptide analogue of the loop containing residue 84 in transthyretin, we have examined the putative local structural effects of this substitution using 1H-NMR spectroscopy. The peptide, containing residues 71-93 of transthyretin with its termini linked via a disulfide bond, was found to possess the same helix-turn motif as in the corresponding region of the crystallographically derived structure of transthyretin in 20% trifluoroethanol (TFE) solution. It therefore, represents a useful model with which to examine the effects of amyloidogenic substitutions. In a peptide analogue containing the Ile84-->Ser substitution it was found that the substitution does not greatly disrupt the overall three-dimensional structure, but leads to minor local differences at the turn in which residue 84 is involved. Coupling constant and NOE measurements indicate that the helix-turn motif is still present, but differences in chemical shifts and amide-exchange rates reflect a small distortion. This is in keeping with observations that several other mutant forms of transthyretin display similar subunit interactions and those that have been structurally analysed possess a near native structure. We propose that the Ser84 mutation induces only subtle perturbations to the transthyretin structure which predisposes the protein to amyloid formation.  (+info)

Initiation of mammalian liver development from endoderm by fibroblast growth factors. (8/852)

The signaling molecules that elicit embryonic induction of the liver from the mammalian gut endoderm or induction of other gut-derived organs are unknown. Close proximity of cardiac mesoderm, which expresses fibroblast growth factors (FGFs) 1, 2, and 8, causes the foregut endoderm to develop into the liver. Treatment of isolated foregut endoderm from mouse embryos with FGF1 or FGF2, but not FGF8, was sufficient to replace cardiac mesoderm as an inducer of the liver gene expression program, the latter being the first step of hepatogenesis. The hepatogenic response was restricted to endoderm tissue, which selectively coexpresses FGF receptors 1 and 4. Further studies with FGFs and their specific inhibitors showed that FGF8 contributes to the morphogenetic outgrowth of the hepatic endoderm. Thus, different FGF signals appear to initiate distinct phases of liver development during mammalian organogenesis.  (+info)

Wild-type transthyretin amyloid (WTTA), also known as senile systemic amyloidosis (SSA) and abbreviated as ATTR, is a disease that typically affects the heart and tendons of elderly people. It is caused by accumulation of a wild-type (that is to say a normal) protein called transthyretin. This is in contrast to a related condition called transthyretin-related hereditary amyloidosis where a genetically mutated transthyretin protein tends to deposit at a much earlier age than in WTTA, due to abnormal conformation and bioprocessing. It belongs to a group of diseases called amyloidosis, chronic progressive conditions linked to abnormal deposition of normal or abnormal proteins, because these proteins are misshapen and cannot be properly degraded and eliminated by the cell metabolism. Wild-type transthyretin amyloid accumulates mainly in the heart, where it causes stiffness and often thickening of its walls, leading consequently to shortness of breath and intolerance to exercise, called diastolic ...
BACKGROUND: This study investigated whether a relationship exists between the presence of de novo antibodies and the clinical manifestations of familial amyloidotic polyneuropathy (FAP). METHODS: Serum samples were collected from 25 Japanese and 6 Swedish FAP amyloidogenic transthyretin (ATTR) Valine30Methionine (V30M) patients, 4 asymptomatic Japanese ATTR V30M gene carriers, and 24 Japanese healthy volunteers. Study methods included enzyme-linked immunosorbent assay (ELISA) and mass spectrometry. RESULTS: Three Japanese and 5 Swedish patients had significantly higher levels of antibodies against ATTR than did healthy volunteers and asymptomatic gene carriers (P,0.05). All 8 patients with higher antibody levels were late-onset cases. The ratio of wild-type TTR to ATTR V30M in serum from the high-antibody group was higher than that of the low-antibody group. ELISA results revealed two epitopes at positions 24-35 and 105-115 of ATTR V30M. We found a significant positive correlation between levels ...
2B77: Human transthyretin (TTR) complexed with Diflunisal analogues- TTR.2,4-DICHLORO-4-HYDROXY-1,1-BIPHENYL-3-CARBOXYLIC ACID
The tetrameric thyroxine transport protein transthyretin (TTR) forms amyloid fibrils upon dissociation and monomer unfolding. The aggregation of TTR causes life-threatening transthyretin amyloidosis (ATTR) associated with three conditions traditionally known as senile systemic amyloidosis, familial amyloidotic polyneuropathy, and familial amyloidotic cardiomyopathy. Senile systemic amyloidosis is a late onset disease in which Tafamidis, a TTR tetramer stabilizer, has been recently approved in Europe; it delays progression of the disease. Several other therapeutics are currently in clinical trials, including other tetramer stabilizers such as diflunisal and RNAi therapies that cause a decrease in the production of TTR protein. Additional approaches are needed to prevent ATTR, and here we explore the use of peptide inhibitors that block aggregation of TTR. Several models of the TTR amyloid spine have been proposed, but the aggregation-prone segments of the protein remain uncertain. Based on the ...
The pathophysiology of the hemodynamic responses to postural stress in familial amyloidotic polyneuropathy (FAP) remains to be elucidated. The aim of the study was to evaluate hemodynamic responses after tilt reversal in FAP. Systolic blood pressure (BP) and heart rate variability (HRV) were analyzed in the baseline, 70° upright position, and after tilt reversal in 15 FAP patients and 14 healthy controls. Beat-to-beat BP was recorded with a Finapres device. Maximum systolic BP after tilt reversal was increased with 22±13 mm Hg in FAP patients as compared with baseline (BP overshoot), whereas controls showed a significantly lower BP overshoot (8±6 mm Hg, P,0.001). In all states, total spectral power and the power of the low and high frequency components were all significantly lower than those of the controls (P,0.01). In a linear regression analysis adjusted for age, we found a significant inverse relation between BP overshoot and HRV (total spectral power, power of the low-frequency and ...
Transthyretin amyloidosis is caused by deposition of hepatocyte-derived transthyretin amyloid in peripheral nerves and heart.

The RNAi resulted in sustained reduction of transthyretin levels. This study establishes a proof of concept for RNAi therapy targeting messenger RNA transcribed from a disease-causing gene.. ...
Transthyretin (TTR) is one of thirty non-homologous proteins whose misfolding, dissociation, aggregation, and deposition is linked to human amyloid diseases. Previous studies have identified that TTR amyloidogenesis can be inhibited through stabilization of the native tetramer state by small molecule binding to the thyroid hormone sites of TTR. We have evaluated a new series of β-aminoxypropionic acids (compounds 5-21), with a single aromatic moiety (aryl or fluorenyl) linked through a flexible oxime tether to a carboxylic acid. These compounds are structurally distinct from the native ligand thyroxine and typical halogenated biaryl NSAID-like inhibitors to avoid off-target hormonal or anti-inflammatory activity. Based on an in vitro fibril formation assay, five of these compounds showed significant inhibition of TTR amyloidogenesis, with two fluorenyl compounds displaying inhibitor efficacy comparable to the well-known TTR inhibitor diflunisal. Fluorenyl 15 is the most potent compound in this series
1ETB: The x-ray crystal structure refinements of normal human transthyretin and the amyloidogenic Val-30Met variant to 1.7-A resolution.
TY - JOUR. T1 - Pathogenesis of transthyretin amyloidosis. AU - Benson, Merrill. PY - 2012/6. Y1 - 2012/6. N2 - Current dogma for transthyretin (TTR) pathogenesis is that mutations in TTR alter its structure such that the tetramer becomes unstable and prone to release of monomer which then becomes the putative building block of the fibril. This hypothesis is supported by thermodynamic data showing decreased stability of mutant TTR tetrameric proteins and accelerated fibril formation under acidic conditions in vitro. There are, however, a number of questions that are not readily answered by this simplistic model of a very complex disease. Worrisome questions still to be answered include: 1. If the monomer is the precursor of the fibril, why do fibril deposits contain large amounts of wild-type TTR and not just variant 2. If destabilized tetramers can form fibrils in vitro, why do we consistently find partial proteolysis of fibril subunit proteins If enzymatic proteolysis is a required step in ...

Amyloidosis is a disorder resulting from the abnormal deposition of a particular protein in various tissues of the body. The four most common forms of amyloidosis are: (1) light chain due to immunoglobulins; (2) secondary which is seen in chronic inflammatory states such as rheumatoid arthritis; (3) senile which is typically seen in those over the age of 80; and (4) heriditary. There are at least eight different proteins that have been recognized to cause the hereditary amyloidoses [2]. Of these, the amyloidgenicTTR (ATTR) protein is the most common, with the Val30Met (Portuguese type) being the most prevalent mutation causing ATTR (80% of cases) [2]. The most common manifestation of ATTR is a neuropathy, but clinical manifestations vary depending on the location of the mutation. The treatment of hereditary amyloidosis is OLT, which limits further synthesis of the mutated protein, and thus halts further deposition in the organs. The Val30Met mutation typically presents with neuropathy, cardiac ...

The results of the prealbumin test give a general idea of a persons nutrition; if the levels of prealbumin are lower than normal, this may also indicate that other substances, chemicals and proteins are also lacking. If levels are low, the patient will probably be advised to change their diet; if they are very low, they may be diagnosed with malnutrition and this will require immediate treatment. Low levels of prealbumin are often seen in patients with chronic or serious health conditions, including cancer, liver disease, severe infections and hyperthyroidism. High levels of prealbumin may also be caused by health conditions; illnesses that may cause high prealbumin levels include Hodgkins disease and overactive adrenal glands; long-term use or high doses of corticosteroids may also cause levels to increase. ...
Familial transthyretin amyloid polyneuropathy. Curator: Larry H. Bernstein, MD, FCAP. LPBI. First-Ever Evidence that Patisiran Reduces Pathogenic, Misfolded TTR Monomers and Oligomers in FAP Patients. We reported data from our ongoing Phase 2 open-label extension (OLE) study of patisiran, an investigational RNAi therapeutic targeting transthyretin (TTR) for the treatment of TTR-mediated amyloidosis (ATTR amyloidosis) patients with familial amyloidotic polyneuropathy (FAP). Alnylam scientists and collaborators from The Scripps Research Institute and Misfolding Diagnostics, Inc. were able to measure the effects of patisiran on pathogenic, misfolded TTR monomers and oligomers in FAP patients. Results showed a rapid and sustained reduction in serum non-native conformations of TTR (NNTTR) of approximately 90%. Since NNTTR is pathogenic in ATTR amyloidosis and the level of NNTTR reduction correlated with total TTR knockdown, these results provide direct mechanistic evidence supporting the therapeutic ...

Purpose: Few scintigraphic tracers are informative on myocardial amyloid infiltration. We aimed to assess: the accuracy of 99mTc-DPD scintigraphy in differential diagnosis between primary (AL) and transthyretin-related (TTR) (both mutant and wild-type) echocardiographically diagnosed amyloidotic cardiomyopathy (AC); the role of 99mTc-DPD in detecting cardiac amyloidosis across a wide spectrum of myocardial involvement in TTR amyloidosis; the prognostic role of 99mTc-DPD in TTR etiology.. Methods: We evaluated: 39 patients with AL-AC; 55 patients with TTR-AC (37 mutant; 19 wild-type); 21 hereditary TTR (ATTR) patients or asymptomatic TTR mutations carriers (6 Val30Met, 15 non-Val30Met) without any echocardiographic abnormalities. Myocardial uptake of 99mTc-DPD (740 MBq iv) was semiquantitatively/visually assessed at 3 h (and 5 min).. Results:. Semiquantitative measures of late (3 h) 99mTc-DPD uptake were ∼2-3 fold higher in TTR-AC (table). A visual score = 2 was accurate in identifying TTR ...
The National Kidney Foundation K/DOQI Guidelines state that, "Serum prealbumin is a valid and clinically useful measure of protein-energy nutritional status in maintenance dialysis (MD) patients." Prealbumin, also known as serum transthyretin (TTR), was not recommended as a nutritional parameter of the same usefulness as the serum albumin. This decision was made, in part, because published research at that time suggested that serum TTR was not a more sensitive index of nutritional status than serum albumin and there was much more clinical and research experience with serum albumin as a nutritional and inflammatory marker. Evidence, including more recently published research data, which is reviewed in this paper has led to the following conclusions by the current authors: 1) In MD patients either protein-energy malnutrition or inflammation can lead to a reduction in serum TTR concentrations. 2) Hence, in MD patients, serum TTR concentrations can be used as a measure of both nutritional and ...
Familial amyloidotic polineuropathy is a genetic disorder, leading to systemic amyloid deposits, manifested as sensory-motor and autonomic neuropathy. In the Portuguese classical form, the disease is evident at a young age, and causes death if no specific treatment is received. Variability in penetrance, age of onset and clinical course has been published; environmental and genetic factors are believed to contribute to this variability. The authors report a case of a 51-year-old white female, with a medical history of acquired angioedema, late-onset familial amyloidotic polineuropathy and systemic lupus erythemathosus. The authors consider that these associated diseases could modulate their expression ...

Although human transthyretin (TTR) is associated with systemic amyloidoses, an anti-amyloidogenic effect that prevents Aβ fibril formation in vitro and in animalmodels has been observed. Herewe studied the ability of three different types of TTR, namely human tetramers (hTTR),mouse tetramers (muTTR) and an engineered monomer of the human protein (M-TTR), to suppress the toxicity of oligomers formed by two different amyloidogenic peptides/proteins (HypF-N and Aβ42). muTTR is the most stable homotetramer, hTTR can dissociate into partially unfolded monomers, whereas M-TTR maintains a monomeric state. Preformed toxic HypF-N and Aβ42 oligomers were incubated in the presence of each TTR then added to cell culture media. hTTR, and to a greater extent MTTR, were found to protect human neuroblastoma cells and rat primary neurons against oligomer-induced toxicity, whereas muTTR had no protective effect. The thioflavin T assay and site-directed labeling experiments using pyrene ruled out disaggregation ...

The disease phenotype of transthyretin (TTR) is dramatically influenced by single point mutations in the TTR gene. Herein, we report on a novel mutation D99N (Asp99Asn) in TTR found in a Danish kindred. None of the family members carrying this mutation have so far shown any clinical signs of amyloidosis. One carrier found compound heterozygous for TTR D99N and L111M (Leu111Met) associated with cardiac amyloid is asymptomatic (42 years). Disease severity can often be linked to both the kinetics of fibril formation and the degree of destabilisation of the native state. In this study, we show that the thermodynamic stability and rate of tetramer dissociation of the variant TTR D99N is unchanged or slightly more stable than wild type (WT) TTR. Furthermore, the in vitro fibrillation kinetics of the variant reveals an unchanged or slightly suppressed tendency to form fibrils compared to WT. Thus, the in vitro experiments support the lack of clinical symptoms observed so far for the TTR D99N carriers. ...
Transthyretin (TTR) is a transport protein in the serum and cerebrospinal fluid that carries the thyroid hormone thyroxine (T4) and retinol-binding protein bound to retinol. This is how transthyretin gained its name: transports thyroxine and retinol. The liver secretes transthyretin into the blood, and the choroid plexus secretes TTR into the cerebrospinal fluid. TTR was originally called prealbumin (or thyroxine-binding prealbumin) because it ran faster than albumin on electrophoresis gels. It functions in concert with two other thyroid hormone-binding proteins in the serum: In cerebrospinal fluid TTR is the primary carrier of T4. TTR also acts as a carrier of retinol (vitamin A) through its association with retinol-binding protein (RBP) in the blood and the CSF. Less than 1% of TTRs T4 binding sites are occupied in blood, which is taken advantage of below to prevent TTRs dissociation, misfolding and aggregation which leads to the degeneration of post-mitotic tissue. Numerous other small ...
Neuropathies are generalised disorders of the peripheral nervous system, due to deranged function of the peripheral motor, sensory and autonomic neurons, their fibres or their myelin sheath. Dysfunction of unmyelinated C and myelinated Aδ fibres causes symptoms like insensitivity or hypersensitivity to heat and/or cold and neuropathic pain. These fibres have slow conduction velocities, carrying temperature feeling and pain sensations from nociceptors and thermoreceptors respectively. An isolated disturbance of these fibres leads usually to the diagnosis of small fibre neuropathy (SFN). The pathogenesis of SFN may be of inflammatory, autoimmune, metabolic, toxic or hereditary nature. Careful clinical and electrodiagnostic assessment, with attention to the pattern of involvement and the types of nerve fibers most affected, narrows the differential diagnosis and helps to focus the laboratory evaluation.. Beside the frequent genetic etiologies in PNP (pmp22, MFN2) one cause of a genetic ...
Results Out of 160 patients evaluated at baseline, 158 (20:138 M:F) had complete follow-up data. Mean age was 60.5±11.1 years, diffuse and limited cutaneous patients were 24 and 134 respectively. Main autoantibody reactivities were anticentromere (n=83, 52%) and anti-topoisomerase I (n=29, 18%). An active disease was present in 27 (17%) patients, malnutrition in 24 (15%). Low prealbumin serum concentrations (,20 mg/dl) were detected in 23 (14.5%). Lung involvement (interstitial or vascular) was present in 43 subjects (27%), gastroenteric tract abnormalities in 82 (52%). After a mean follow-up of 3.8 (2.6-4.5) years, 11 (7%) patients had died (9 of SSc-related causes, 2 of cancer complications). Low prealbumin serum levels were significantly associated to a worse survival (univariate HR= 4.89, 1.36-17.56, p=0.015), even when corrected for other significant predictors of mortality in bivariate analyses (lung involvement, g-i involvement, presence of other comorbidities). When evaluated in ...
Computer graphics image of human prealbumin (also called transthyretin), a plasma protein which acts as a storage & carrier molecule for the thyroid hormone thyroxine (T4). It is also independently involved in the transport of Vitamin A due to its ability to bind retinol-binding protein. Transthyretin consists of a functional tetramer composed of four identical subunits, each of molecular weight 14, 000 and formed of a chain of 127 amino-acid residues. Here, the alpha carbon backbone of each monomer is shown in orange, purple, blue & green. The T4 binding channel runs through the centre of this image. - Stock Image A617/0020
Proteins are versatile molecules that play a variety of roles in maintaining the human body, e.g. transport of nutrients. Transthyretin (TTR) is a 55 kDa homotetrameric protein found in human plasma and in the cerebrospinal fluid, responsible for the transport of retinol (vitamin A) and T4 (thyroxine). This protein is probably not essential for life, since TTR knockout mice have normal fetal development and lifespan. TTR, like 25 other human proteins, has been associated to the deposition of amyloid aggregates. Previous research has shown that mutations considerably increase the propensity of the protein to form aggregates. However, the wild type protein also exhibits this ability to aggregate, giving rise to the senile systemic amyloidosis disease that affects 20% people over 80 years of age. It is well accepted that self-association of monomeric subunits triggers the disease through tetramer dissociation, since stabilization of the quaternary structure suppresses aggregate formation.. However, ...

Describes how the prealbumin test is used, when a prealbumin test is ordered, and what the results of a prealbumin test might mean
There are some interesting points in the study from the Sun lab that seem to add to general themes found in diseases associated with amyloid aggregation. In all of these diseases, inclusions consisting of an endogenously produced protein mark the progression of the disease. What exactly causes the previously soluble and physiological form of the protein to change conformation into a pathological form and aggregate is in most cases unclear.. In the case of transthyretin (TTR), a serum protein involved in familial amyloidotic polyneuropathy, a destabilization event induced by either a missense mutation or an external insult leads to depolymerization of the natively tetrameric protein, which then leaves it open to amyloidogenic polymerization (Quintas et al., 1999). The native form, stabilized by its natural ligand thyroxin, is aggregation-resistant. Our lab has recently discovered that a very similar situation can be found for α-synuclein (αS), a mostly neuronally expressed protein of unknown ...

Fifty years ago, the focus on the Val30Met type of the disease, in which neurologic manifestations predominate, led to the widespread notion that hereditary transthyretin-related amyloidosis (ATTR) was essentially a neurologic disease. It is now clear that ATTR is extremely heterogeneous on both genotypic and phenotypic grounds. The clinical spectrum of the disease ranges from an almost exclusive neurologic involvement to strictly cardiac manifestations. This heterogeneity is linked to several factors including specific transthyretin mutations, geographic distribution and endemic vs. non-endemic aggregation type. The existence of exclusively or predominantly cardiac phenotypes makes the recognition of the disease very challenging since it can mimic other more common causes of left ventricular "hypertrophy". Assessment of such patients should include an active search for possible red flags that can indicate the correct final diagnosis. More in general the clinician must be aware that: ...
RESULTS. 3 patients received a domino graft (from a donor transplanted for familial amyloidotic polyneuropathy); 2 a living related donor graft and 2 a cdaver graft. 5 of the 7 are alive, and as the presenter said 4 are "alive and well", but post transplant experience can have complications which are described below. The average followup time for these patients is 12.8 months (4-30 months). The longest a patient is alive who is doing well is 30 months. In general transplant experience is that patients with hepatitis B have better outcomes than patients with hepatitis C. 3 patients are doing relatively well. The study presenter said 4 of the 7 patients have shown dramatic improvement. 1 patient is in good condition at month 30 and is HCV negative. a second patient has F1 fibrosis at month 12 of followup with low or undetectable HIV RNA and in good condition. A third patient is in good condition at month 18 of followup. Three patients are not doing well. Another patient is alive with F3 fibrosis ...

OBJECTIVES: Cardiomyopathy is a major cause of death in both the hereditary form of transthyretin (TTR) amyloidosis and the sporadic late-age-onset transthyretin amyloidosis (ATTR wild-type (ATTRwt)). Clinically disease progression from time of diagnosis to death is usually quoted as 5- to 15-years. In prior studies, significant progression of cardiac parameters in patients with moderate to severe cardiomyopathy has been noted within a 12-month time span. METHODS: The present study was designed to prospectively monitor changes in cardiac parameters, both structural and functional, in patients with ATTR cardiomyopathy while treated with a TTR specific antisense oligonucleotide (ASO; IONIS-TTR℞) designed to lower blood levels of the amyloid fibril precursor protein ...

Transthyretin (TTR) is a homotetrameric plasma protein that, as a result of a set of not yet fully characterized conformational changes, forms fibrillar aggregates that are the major protein component of amyloid deposits. More than 80 mutations associated with TTR amyloid deposition have been described in the literature. X-ray crystallography was used to elucidate the three-dimensional structure of two important TTR variants: TTR Y78F, an amyloidogenic protein, and TTR R104H, which is associated with a protective effect over the amyloidogenic V30M mutation. The structures of those two TTR variants have been determined in space group P2(1)2(1)2 to 1.55 and 1.60 angstroms resolution, respectively, using molecular-replacement techniques. Detailed analysis of the protein model for TTR Y78F indicates a destabilization of the contacts between the alpha-helix and AB loop and the body of the molecule, intimately related to the amyloidogenic nature; contrastingly, in the TTR R104H variant new contacts ...
Alzheimers Disease. As people live longer, thanks to better nutrition, healthcare and improved working conditions, an increasing number of elderly patients are being diagnosed with Alzheimers disease, involving the long-term loss of memory. Now scientists at the Scripps Research Institute have discovered that a protein could help in the prevention or delay of this disease.1. The protein transthyretin (TTR) is formed as a "tetramer", a four-unit structure. Old age can cause the tetramers to disintegrate into aggregates called amyloids, accumulating in various organs and causing diseases. In the mid-1990s, however, several laboratories indicated that TTR in the brain might actually protect against other amyloids such as amyloid beta, associated with Alzheimers disease.. In transgenic "Alzheimers mice", which overproduce amyloid beta, TTR overproduction was found to reduce the memory deficits of the mice. Further experiments showed that TTR tetramers bind to amyloid beta, inhibiting it from ...

That could all play out to Alnylams benefit. Its lead late-stage drug patisiran could prove a safer alternative to Ionis drug, which is why the Cambridge-based biotechs shares shot up 15% this morning.. When the safety issue first came up last year, triggering the hold, GSK opted to shelve plans for a Phase III study of TTR amyloid cardiomyopathy.. Transthyretin - or TTR - amyloidosis is characterized by the gradual accumulation of amyloid in tissue and organs that lead to death.. Ionis stock was hit last week when an FDA warning letter was circulated highlighting the case of an investigator in a separate study who failed to properly test platelet levels in patients. Some of the analysts following the company noted that it raised some serious issues on safety related to its real-world use - how could physicians be expected to monitor platelet levels effectively if researchers dont - and the stock, subject to repeated short attacks, took a hit. That issue will likely to be closely considered ...
Back pain is commonly reported among adults in the U.S., it is the second most common reason adults seek medical treatment. There is steady growth in the number of older adults seeking spine surgeries, especially complex surgeries. Additionally, the number of citizens over the age of 65 is steadily increasing and will continue to increase over the next several decades. The rising number of older adults seeking spine surgery raises concern for the well-being of this population given the risk of complications in spine surgery. It is imperative for clinicians to understand all potential risk factors for their patients undergoing surgery. Protein malnutrition is a risk factor for postoperative morbidity and mortality. While there is no universally accepted pre-operative measure of nutrition status, certain blood biomarkers are recognized as clinically important in evaluating patients pre-surgical nutrition status. To further evaluate pre-surgical biomarkers and risk of complications we conducted a

Familial transthyretin amyloidosis (ATTR) is a rare, life-threatening, autosomal dominant disease involving mainly the heart and the peripheral nervous system due to a point mutation of the transthyretin (TTR) gene. By removing the main source of the mutated TTR, liver transplantation (LT) has become the standard treatment for ATTR (1). Because the demand for liver grafts exceeds the number of available organs and because new treatments have recently emerged, screening patients at high risk of death after LT is critical (2).. We identified 215 consecutive patients who underwent LT between 1993 and 2011. The diagnosis was made by the observation of both amyloid deposits in biopsy specimens and a TTR mutation. The pre-operative evaluation included physical examination, electrocardiography, echocardiography, autonomic dysfunction score, and polyneuropathy disability score (PND) calculation. The primary study endpoint was all-cause mortality after LT. The prognostic model predicting the individual ...
Hereditary transthyretin amyloidosis (ATTRv amyloidosis) is caused by a variant transthyretin (TTR), which is a serum protein secreted by the liver. Mass spectrometry (MS) is a useful tool that can detect variant TTRs in serum samples from patients with ATTRv amyloidosis. We previously reported several mass spectrometric methods to detect variant TTRs in serum samples. Those methods require cumbersome immunoprecipitation with anti-TTR antibodies and significant time to analyze the variant TTRs. In our study here, we developed a new simple and quick method to detect variant TTRs in serum samples by means of matrix-assisted laser desorption-ionization time-of-flight (MALDI-TOF) MS without immunoprecipitation (direct MALDI). By using direct MALDI, we analyzed 288 serum samples obtained from patients who were clinically suspected having amyloidosis to investigate the usefulness of this direct MALDI method to detect variant TTRs in serum samples. The method completed the process within 30 min. We
Hereditary transthyretin amyloidosis (ATTR amyloidosis) is a rare, genetically heterogenous, and clinically variable autosomal dominant disease that severely reduces life expectancy. As treatment options grow, a proper diagnostic approach is mandatory especially in non-endemic regions with diverse genetic backgrounds. We examined 102 neuropathy patients at a German neuromuscular centre. Common causes of polyneuropathy were ruled out by medical history and extensive laboratory testing to define a cohort of patients with progressive polyneuropathy classified as idiopathic. Molecular genetic testing of the entire TTR gene was performed, and the detected amyloidogenic and non-amyloidogenic variants were associated with the observed clinical phenotypes and results of prior diagnostic testing. Two of 102 patients tested positive for amyloidogenic mutations (p.Ile127Val and p.Glu81Lys), while a variant of unknown significance, p.Glu26Ser, was found in 10 cases. In both positive cases, previous negative biopsy

This is the first reported case of familial amyloid cardiomyopathy associated with TTR Ile122 in a white patient. The Ile122 mutation is present in 4% of African Americans and usually results in isolated cardiac amyloidosis from age 60 years onwards, presenting with cardiac failure and/or arrhythmia. Occasionally, there is associated carpal tunnel syndrome, and peripheral polyneuropathy has been reported.3 Amyloid deposits of wild-type TTR are found in 25% of hearts from people over 80 years old, examined after death.6 These deposits do not always cause clinical symptoms but the possibility of amyloidosis should be considered when treating elderly patients with heart failure, particularly in cases resistant to conventional treatment with diuretics and ACE inhibitors. The diagnosis of cardiac amyloidosis is suggested by an ECG showing small complexes and/or anterior Q waves in association with concentric left ventricular hypertrophy or restrictive physiology and occasionally a speckled myocardium ...
Results were recently published for the first trial of CPHPC as a therapy to clear out age-related deposits of the type of amyloid formed from misfolded transthyretin, normally responsible for transporting the thyroid hormone thyroxine in blood and cerebrospinal fluid. Amyloids are one of the distinguishing features of older tissues, and clearing them will be one of the necessary outcomes produced by any comprehensive suite of rejuvenation therapies developed in the near future.. The accumulation of transthyretin amyloid creates a condition known as senile systemic amyloidosis where it occurs to varying degrees for everyone in later life, and TTR amyloidosis when it arises in young people due to inherited mutations. Senile systemic amyloidosis is known to be responsible for a sizable fraction of deaths in supercentenarians, as the amyloid deposits clog the cardiovascular system to the point of failure. This process is also thought to play an underappreciated role in heart failure in the younger ...
Transthyretin (TTR) amyloidoses are familial or sporadic degenerative conditions that often feature heavy cardiac involvement. Presently, no effective pharmacological therapy for TTR amyloidoses is available, mostly due to a substantial lack of knowledge about both the molecular mechanisms of TTR aggregation in tissue and the ensuing functional and viability modifications that occur in aggregate-exposed cells. TTR amyloidoses are of particular interest regarding the relation between functional and viability impairment in aggregate-exposed excitable cells such as peripheral neurons and cardiomyocytes. In particular, the latter cells provide an opportunity to investigate in parallel the electrophysiological and biochemical modifications that take place when the cells are exposed for various lengths of time to variously aggregated wild-type TTR, a condition that characterizes senile systemic amyloidosis. In this study, we investigated biochemical and electrophysiological modifications in ...
In this, the largest ever CMR study in patients with amyloidosis, we found that native myocardial T1 mapping has a high diagnostic accuracy for cardiac amyloid for both AL and ATTR when compared against HCM, a relevant clinical differential diagnosis. Furthermore, T1 tracks cardiac amyloid burden in both diseases, and is more sensitive for detecting early disease in gene mutation carriers than LGE imaging. In both amyloid types, T1 tracks markers of systolic and diastolic function, mass, and prognostic markers. In ATTR amyloid, T1 additionally correlates with ECG PR and QRS duration and indexed left atrial area, whereas in AL type, it correlates with reductions in limb lead voltages. T1 also has functional associations with a reduction in 6-min walk test in ATTR amyloidosis. Interestingly and perhaps unexpectedly (16), T1 elevation was lower in ATTR compared with AL type.. Amyloidosis is considered the exemplar of an interstitial disease, as the quantity of amyloid in the extracellular space ...
The liver has become an increasingly interesting target for oligonucleotide therapy. Mutations of the gene encoding transthyretin (TTR), expressed in vast amounts by the liver, result in a complex degenerative disease, termed familial amyloid polyneuropathy (FAP). Misfolded variants of TTR are linked to the establishment of extracellular protein deposition in various tissues, including the heart and the peripheral nervous system. Recent progress in the chemistry and formulation of antisense (ASO) and small interfering RNA (siRNA) designed for a knockdown of TTR mRNA in the liver has allowed to address the issue of gene-specific molecular therapy in a clinical setting of FAP. The two therapeutic oligonucleotides bind to RNA in a sequence specific manner but exploit different mechanisms. Here we describe major developments that have led to the advent of therapeutic oligonucleotides for treatment of TTR-related disease.. ...
A Phase 3 Multicenter Multinational Randomized Double-blind Placebo-controlled Study to Evaluate the Efficacy and Safety of Patisiran (ALN-TTR02) in Transthyretin (TTR)-Mediated Polyneuropathy (Familial Amyloidotic Polyneuropathy - FAP) (APOLLO)
In cardiac amyloidosis, myocardial tissue histology reveals among its salient features, the expansion of the extracellular space, the accumulation of amyloid protein, and collagen fiber deposition. At the cellular level, cytoplasmic vacuolization and decline of myofibrils are commonly seen in endomyocardial biopsies from amyloid patients. There is evidence that human amyloidogenic light (AL) chain proteins have a cardiotoxic effect (1), which is associated with impaired cardiomyocyte contractile function and increased cell death. Of similar relevance for transthyretin-related amyloidosis (ATTR) is the fact that transthyretin (TTR) also has a cytotoxic effect (2), causing increased inflammatory and oxidative stress. How well cardiac magnetic resonance (CMR) can identify various aspects of pathological tissue remodeling in cardiac amyloidosis remains a question of intense research interest.. Over the last decade, CMR has identified a series of promising image-based markers tied to cardiomyopathic ...

OBJECTIVES: The aim of this study was to compare left ventricular longitudinal strain (LS) evaluated by 2-dimensional echocardiography with cardiac magnetic resonance (CMR) in cardiac amyloidosis (CA), establish correlations between histological and imaging findings, and assess the prognostic usefulness of LS measurement and CMR.. BACKGROUND: CA is a condition with a poor prognosis due chiefly to 3 forms of amyloidosis: light-chain amyloidosis (AL), hereditary transthyretin (M-TTR), and wild-type transthyretin (WT-TTR). Two-dimensional echocardiography measurement of LS has been reported to detect early left ventricular systolic dysfunction. The pathophysiological underpinnings, regional distribution, and prognostic significance of LS in CA are unclear.. METHODS: All patients underwent echocardiography, and 53 underwent CMR. The native hearts of the 3 patients who received heart transplants were subjected to histological examination. For each of the 17 left ventricular segments in the American ...

Amyloidosis, transthyretin-related (AMYL-TTR) [MIM:105210]: A hereditary generalized amyloidosis due to transthyretin amyloid deposition. Protein fibrils can form in different tissues leading to amyloid polyneuropathies, amyloidotic cardiomyopathy, carpal tunnel syndrome, systemic senile amyloidosis. The disease includes leptomeningeal amyloidosis that is characterized by primary involvement of the central nervous system. Neuropathologic examination shows amyloid in the walls of leptomeningeal vessels, in pia arachnoid, and subpial deposits. Some patients also develop vitreous amyloid deposition that leads to visual impairment (oculoleptomeningeal amyloidosis). Clinical features include seizures, stroke-like episodes, dementia, psychomotor deterioration, variable amyloid deposition in the vitreous humor. {ECO:0000269,PubMed:10036587, ECO:0000269,PubMed:10071047, ECO:0000269,PubMed:10211412, ECO:0000269,PubMed:10436378, ECO:0000269,PubMed:10439117, ECO:0000269,PubMed:10611950, ...
Our study, which includes the largest series so far of patients with TTR-related CA comprehensively studied by both conventional echocardiography and 2D STI, supports the role of myocardial deformation imaging as a sensitive tool for characterizing LV dysfunction in CA over more traditional echocardiographic parameters. Our findings provide insights into the pathophysiological mechanisms underlining LV dysfunction in amyloid heart disease, suggesting a role for specific pathogenesis and LV wall thickness in determining LV dysfunction. Along with pathogenesis, LV LS was found to be an independent predictor of overall survival, confirming the previously observed prognostic significance of strain in patients with AL amyloidosis.. CA is commonly considered a form of restrictive cardiomyopathy, and the pathophysiology of HF has traditionally been attributed to diastolic dysfunction. Only a few studies have assessed the individual contributions of systolic and diastolic dysfunction to the ...
Amyloid fibrils are associated with a range of highly debilitating neurological disorders including Alzheimers disease, Parkinsons disease and the spongiform encephalopathies. These structures are formed by the misfolding and self-assembly of peptides and proteins varying widely in sequence and in native conformation. Here we combine experimental measurements derived from sold-state NMR, X-ray fibre diffraction and Atomic Force Microscopy to determine the complex, higher order protofilament structure adopted by an 11-amino acid peptide fragment of the human plasma protein transthyretin, TTR(105-115). This determination of the structure of amyloid fibrils to atomic resolution is crucial to the understanding of non-native protein self-assembly and the molecular basis of protein deposition diseases. We then demonstrate that amyloid fibrils, ordered supramolecular structures that we self-assemble from a wide range of polypeptide molecules, constitute a class of high-performance biomaterials and ...
Pfizer may have impressed pharma watchers Monday with its blockbuster data on transthyretin cardiomyopathy candidate tafamidis. But that doesnt mean Alnylam and its newly approved Onpattro are suddenly out of the running.
Cells were isolated by mechanical and enzymatic treatment of freshly isolated porcine plexus tissue. Epithelial cell monolayers were grown and CSF secretion and transepithelial resistance were determined. The expression of f-actin as well as the choroid plexus marker protein transthyretin (TTR), were assessed. Permeability studies with marker compounds of different molecular weight were performed in order to assess monolayer integrity. The expression of the export proteins p-glycoprotein (Pgp, Abcb1) multidrug resistance protein1 (Mrp1, Abcc1) and Mrp4 (Abcc4) was studied by RT-PCR, Western-blot and immunofluorescence techniques and their functional activity was assessed by transport and uptake experiments.. Choroid plexus epithelial cells were isolated in high purity and grown to form confluent monolayers. Filter-grown monolayers displayed transendothelial resistance (TEER) values in the range of 100 to 150 Ohm x cm2. Morphologically, the cells showed the typical net work of f-actin and ...
Results: Fourteen subjects with a mean age of 12.3 years (8-17, range) were enrolled. PCDAI scores significantly decreased from pretreatment (34.2 3.3) to eight-week scores (21.7 3.9) with naltrexone therapy (p=0.005). Only the naltrexone and not placebo-treated subjects had PCDAI scores less than 30 during the first 8 weeks and improvement in the Harvey Bradshaw activity index (p=0.03). Systemic and social quality of life improved (p=0.035), and no serious side effects were noted. Twenty- five percent were considered in remission (score , 10) and 50% had improved with mild disease activity (, 30) at the end of the study.there were no increases in the liver transaminases, electrolyte, renal or glucose abnormalities noted. Prealbumin levels improved 2.5-fold more in naltrexone treated patients over placebo control, suggesting improved nutritional status. ESR values decreased 2.4 more in naltrexone treated patients compared to placebo treated patients during the first eight weeks of the ...

The main goal of the ongoing patisiran phase 3 trial is to show improvement in the measurable level of impairment due to nerve damage against a placebo group, using the modified Neuropathy Impairment Score+7 test. Among the 24 patients treated with patisiran for 24 months in the phase 2 open-label study, the average score decreased by 6.7 points. The historical average for similar patients without patisiran treatment over 24 months is an increase of between 26 and 30 points. Revusirans ongoing phase 3 trial is looking for an improvement in the six minute walk distance test scores, and a decrease in circulating transthyretin against a placebo group. Alnylam also presented early results from a phase 2 trial with revusiran in patients with more advanced stages of heart damage than the ongoing phase 3 trial. The premature data from revusirans phase 2 trial suggest the drug effectively reduces circulating transthyretin, but its difficult to draw any conclusions from available six minute walk test ...

Results Women had a significantly higher AO, either for daughters (mean: 33.70, SD: 6.84) vs sons (29.43, 6.08); or mothers (39.57, 11.75) vs fathers (35.62, 11.62). Also, 291 pairs showed marked anticipation (≥10 years); the transmitting parent was the mother in 203 pairs. Mother-son pairs showed larger anticipation (10.43, 9.34), while father-daughter pairs showed only a residual anticipation (1.23, 9.77). Gender of offspring and parents was highly significant (with no interaction). To remove possible biases, we repeated analyses: (1) excluding the proband; (2) removing pairs with simultaneous onset; and (3) excluding offspring born after 1960. Anticipation was found in all subsamples, with the same trend for a parent-of-origin effect. Noteworthy, parents with AO ≤40 years never had offspring with AO ≥50.. ...
NSAID Dolobid inhibited familial amyloid polyneuropathy progression(dailyRx News) Familial amyloid polyneuropathy is a very rare condition. New research shows
Familial amyloid polyneuropathy type I is an autosomal dominant disorder caused by mutations in the transthyretin (TTR) gene; however, carriers of the same mutation exhibit variability in penetrance and clinical expression. We analyzed alleles of candidate genes encoding non-fibrillar components of TTR amyloid deposits and a molecule metabolically interacting with TTR [retinol-binding protein (RBP)], for possible associations with age of disease onset and/or susceptibility in a Portuguese population sample with the TTR V30M mutation and unrelated controls. We show that the V30M carriers represent a distinct subset of the Portuguese population. Estimates of genetic distance indicated that the controls and the classical-onset group were furthest apart, whereas the late-onset group appeared to differ from both. Importantly, the data also indicate that genetic interactions among the multiple loci evaluated, rather than single-locus effects, are more likely to determine differences in the age of ...

The 44-year-old man in this study was presented with sudden-onset, persistent epigastralgia and had undergone living donor living transplantation (LDLT) for familial amyloid polyneuropathy at 42 years of age, with the left hepatic lobe graft donated by his wife. During LT, biliary reconstruction was performed by hepaticojejunostomy with a Roux limb via the antecolic route as the common bile duct was removed for the sake of the following domino LT. The peritoneal defect related to Roux-en-Y anastomosis was primarily closed with several 4-0 silk interrupted sutures. Although he had experienced repeated episodes of small bowel obstruction, which had all recovered fully following conservative management, at 5, 9, and 14 months post-transplantation, continuous epigastralgia and repeated vomiting for 7 h during the present admission prompted clinical suspicion of bowel strangulation. Abdominal guarding and rigidity in the epigastric region were noted on examination. The body temperature was 37.1 °C. ...
Background/aim: Little is known about biochemical markers related to change in visual acuity after vitrectomy. The potential use of transthyretin (TTR), a carrier of the retinol/retinol-binding protein, as a biochemical marker protein, was investigated.. Methods: TTR was measured using immunonephelometry in a group of patients (n = 77) in longstanding (,1 week) retinal detachment (n = 29), fresh (,1 week) retinal detachment (n = 17), macular holes (n = 20) or diabetic retinopathy (n = 11). Vitreous samples were taken at the start of every vitrectomy procedure. For reference values, cadaver specimens (n = 73) were used.. Results: Reference values for vitreous TTR (median 18 mg/l; IQR 4 to 24 mg/l) comprised 2.2% of reference values for vitreous protein levels (median 538 mg/l; IQR 269 to 987 mg/l). Vitreous TTR values of patients were comparable in all disorders. Vitreous TTR values were higher in phakic (median 22.5 mg/l; IQR 10 to 27 mg/l) than in pseudophakic patients (median 12 mg/l; IQR 8 to ...
To determine the prevalence of elevated serum concentrations of thyroxine binding globulin (TBG) in patients with hepatocellular carcinoma (HCC) and the influence of the associated cirrhosis, TBG was measured in 39 patients with HCC, 22 with and 17 without cirrhosis, in 20 patients with cryptogenic macronodular cirrhosis but without HCC, and in 40 matched controls. The mean serum TBG concentration in the patients was 34.5 ± 17.7 μg per ml, compared to 21.4 ± 6.8 μg per ml in controls and 20.5 ± 6.3 μg per ml in cirrhosis without HCC (p , 0.01). The presence or absence of cirrhosis in the HCC patients did not significantly influence the frequency with which elevated TBG levels were found; levels were normal in every subject with cirrhosis and no HCC. The mean thyroxine (T4): TBG ratio was 5.58 ± 1.78 in controls and was reduced in HCC patients with both elevated (3.33 ± 0.80, p , 0.001) and normal TBG values (4.39 ± 1.90, p , 0.05), and in cirrhotics without HCC (4.29 ± 1.01, p , 0.01). ...
To our knowledge, this is the first assessment of 99mTc-DPD scintigraphy as a potential diagnostic tool for assessment of etiology in cardiac amyloidosis. Our findings could have potential clinical implications (especially in the light of recent therapeutic advances), and they also could help clarify the conflicting data in published reports on the use of bone tracers in the scintigraphic evaluation of amyloidosis.. Noninvasive detection of amyloid has been investigated using three main groups of radiolabeled tracers: 123I-labeled serum amyloid P protein (26,27); aprotinin (28,29); and bone tracers, mainly 99mTc-pyrophosphate (9-15) and 99mTc-HDP (20,21). Labeled serum amyloid P protein localizes rapidly and specifically to amyloid deposits (in proportion to the amount of amyloid) and persists there, allowing quantitative monitoring of amyloid deposition and regression during therapy (low quality of heart visualization and limited availability are current limitations of this tracer [12,13]). ...
This case report concerns a patient who presented a diagnostic problem of cardiomegaly and myocardial failure of unknown etiology and in whom the outstanding pathologic finding at autopsy was primary systemic amyloidosis with marked cardiac involvement.
