delta-Aminolevulinate synthetases in the liver cytosol fraction and mitochondria of mice treated with allylisopropylacetamide and 3,5-dicarbethoxyl-1,4-dihydrocollidine. (1/369)

Hepatic delta-aminolevulinate (ALA) synthetase was induced in mice by the administration of allylisopropylacetamide (AIA) and 3,5-dicarbethoxy-1,4-dihydrocollidine (DDC). In both cases, a significant amount of ALA synthetase accumulated in the liver cytosol fraction as well as in the mitochondria. The apparent molecular weight of the cytosol ALA synthetase was estimated to be 320,000 by gel filtration, but when the cytosol ALA synthetase was subjected to sucrose density gradient centrifugation, it showed a molecular weight of 110,000. In the mitochondria, there were two different sizes of ALA synthetase with molecular weights of 150,000 and 110,000, respectively; the larger enzyme was predominant in DDC-treated mice, whereas in AIA-treated mice and normal mice the enzyme existed mostly in the smaller form. When hemin was injected into mice pretreated with DDC, the molecular size of the mitochondrial ALA synthetase changed from 150,000 to 110,000. The half-life of ALA synthetase in the liver cytosol fraction was about 30 min in both the AIA-treated and DDC-treated mice. The half-life of the mitochondrial ALA synthetase in AIA-treated mice and normal mice was about 60 min, but in DDC-treated mice the half-life was as long as 150 min. The data suggest that the cytosol ALA synthetase of mouse liver is a protein complex with properties very similar to those of the cytosol ALA synthetase of rat liver, which has been shown to be composed of the enzyme active protein and two catalytically inactive binding proteins, and that ALA synthetase may be transferred from the liver cytosol fraction to the mitochondria with a size of about 150,000 daltons, followed by its conversion to enzyme with a molecular weight of 110,000 within the mitochondria. The process of intramitochondrial enzyme degradation seems to be affected in DDC-treated animals.  (+info)

Four new mutations in the erythroid-specific 5-aminolevulinate synthase (ALAS2) gene causing X-linked sideroblastic anemia: increased pyridoxine responsiveness after removal of iron overload by phlebotomy and coinheritance of hereditary hemochromatosis. (2/369)

X-linked sideroblastic anemia (XLSA) in four unrelated male probands was caused by missense mutations in the erythroid-specific 5-aminolevulinate synthase gene (ALAS2). All were new mutations: T647C, C1283T, G1395A, and C1406T predicting amino acid substitutions Y199H, R411C, R448Q, and R452C. All probands were clinically pyridoxine-responsive. The mutation Y199H was shown to be the first de novo XLSA mutation and occurred in a gamete of the proband's maternal grandfather. There was a significantly higher frequency of coinheritance of the hereditary hemochromatosis (HH) HFE mutant allele C282Y in 18 unrelated XLSA hemizygotes than found in the normal population, indicating a role for coinheritance of HFE alleles in the expression of this disorder. One proband (Y199H) with severe and early iron loading coinherited HH as a C282Y homozygote. The clinical and hematologic histories of two XLSA probands suggest that iron overload suppresses pyridoxine responsiveness. Notably, reversal of the iron overload in the Y199H proband by phlebotomy resulted in higher hemoglobin concentrations during pyridoxine supplementation. The proband with the R452C mutation was symptom-free on occasional phlebotomy and daily pyridoxine. These studies indicate the value of combined phlebotomy and pyridoxine supplementation in the management of XLSA probands in order to prevent a downward spiral of iron toxicity and refractory anemia.  (+info)

Properties of 5-aminolaevulinate synthetase and its relationship to microsomal mixed-function oxidation in the southern armyworm (Spodoptera eridania). (3/369)

1. Activity of 5-aminolaevulinate synthetase was measured in the midgut and other tissues of the last larval instar of the southern armyworm (Spodoptera eridania Cramer, formerly Prodenia eridania Cramer). 2. Optimum conditions for measuring the activity were established with respect to all variables involved and considerable differences from those reported for mammalian enzyme preparations were found. 3. Maximum activity (20 nmol/h per mg of protein) occurs 18-24 h after the fifth moult and thereafter decreases to trace amounts as the larvae age and approach pupation. 4. Synthetase activity was rapidly induced by oral administration (in the diet) of pentamethylbenzene, phenobarbital, diethyl 1,4-dihydro-2,4,6-trimethylpyridine-3, 5-dicarboxylate, and 2-allyl-2-isopropylacetamide. 5. Puromycin inhibited the induction of synthetase by pentamethylbenzene. 6. Induction of 5-aminolaevulinate synthetase correlated well with the induction of microsomal N-demethylation of p-chloro-N-methylaniline, except for phenobarbital, which induced the microsomal oxidase relatively more than the synthetase.  (+info)

Pre-steady-state reaction of 5-aminolevulinate synthase. Evidence for a rate-determining product release. (4/369)

5-Aminolevulinate synthase (ALAS) is the first enzyme of the heme biosynthetic pathway in non-plant eukaryotes and the alpha-subclass of purple bacteria. The pyridoxal 5'-phosphate cofactor at the active site undergoes changes in absorptive properties during substrate binding and catalysis that have allowed us to study the kinetics of these reactions spectroscopically. Rapid scanning stopped-flow experiments of murine erythroid 5-aminolevulinate synthase demonstrate that reaction with glycine plus succinyl-CoA results in a pre-steady-state burst of quinonoid intermediate formation. Thus, a step following binding of substrates and initial quinonoid intermediate formation is rate-determining. The steady-state spectrum of the enzyme is similar to that formed in the presence of 5-aminolevulinate, suggesting that release of this product limits the overall rate. Reaction of either glycine or 5-aminolevulinate with ALAS is slow (kf = 0.15 s-1) and approximates kcat. The rate constant for reaction with glycine is increased at least 90-fold in the presence of succinyl-CoA and most likely represents a slow conformational change of the enzyme that is accelerated by succinyl-CoA. The slow rate of reaction of 5-aminolevulinate with ALAS is 5-aminolevulinate-independent, suggesting that it also represents a slow isomerization of the enzyme. Reaction of succinyl-CoA with the enzyme-glycine complex to form a quinonoid intermediate is a biphasic process and may be irreversible. Taken together, the data suggest that turnover is limited by release of 5-aminolevulinate or a conformational change associated with 5-aminolevulinate release.  (+info)

Phylogenetic analysis of the 5-aminolevulinate synthase gene. (5/369)

The evolution of 5-aminolevulinate synthase (ALS) was studied by acquiring sequence data and generating phylogenetic trees. Gene sequences were already available for a variety of vertebrates (which have both a housekeeping and an erythroid form of the gene), fungi, alpha-proteobacteria, and one protist and one protostome. In order to generate representative trees, ALS sequence data were acquired from various deuterostomes and protostomes. The species and tissues selected for study were beluga whale liver, hagfish blood, sea urchin gonadal tissue, cuttlefish hepatopancreas, horseshoe crab hepatopancreas, and bloodworm blood. The new sequences and those previously published were examined for the presence of heme-regulatory motifs (HRMs) and iron-responsive elements (IREs). The HRMs are present in almost all eukaryotic species, which suggests their fundamental role in the regulation of ALS. The IREs are present in all vertebrate erythroid forms of ALS, which indicates that in those animals, expression of the erythroid form of the enzyme and, hence, hemoglobin production can be influenced by the intracellular content of iron. The new sequences were aligned with previously reported ALS sequences, and phylogenetic analyses were performed. The resulting trees provided evidence regarding the timing of the gene duplication event that led to the two forms of the ALS gene in vertebrates. It appears that the housekeeping and erythroid forms of ALS probably arose before the divergence of hagfish from the deuterostome line leading to the vertebrates. The data also add to the evidence indicating that alpha-proteobacteria are the nearest contemporary relatives of mitochondria.  (+info)

Respiratory uncoupling induces delta-aminolevulinate synthase expression through a nuclear respiratory factor-1-dependent mechanism in HeLa cells. (6/369)

Nuclear respiratory factor (NRF)-1 appears to be important for the expression of several respiratory genes, but there is no direct evidence that NRF-1 transduces a physiological signal into the production of an enzyme critical for mitochondrial biogenesis. We generated HeLa cells containing plasmids allowing doxycycline-inducible expression of uncoupling protein (UCP)-1. In the absence of doxycycline, UCP-1 mRNA and protein were undetectable. In the presence of doxycycline, UCP-1 was expressed and oxygen consumption doubled. This rise in oxygen consumption was associated with an increase in NRF-1 mRNA. It was also associated with an increase in NRF-1 protein binding activity as determined by electrophoretic mobility shift assay using a functional NRF-1 binding site from the delta-aminolevulinate (ALA) synthase promoter. Respiratory uncoupling also caused a time-dependent increase in protein levels of ALA synthase, an early marker for mitochondrial biogenesis. ALA synthase induction by respiratory uncoupling was prevented by transfecting cells with an oligonucleotide antisense to the region of the NRF-1 initiation codon; a scrambled oligonucleotide with the same base composition had no effect. Respiratory uncoupling increases oxygen consumption and lowers energy reserves. In HeLa cells, uncoupling also increases ALA synthase, an enzyme critical for mitochondrial respiration, but only if translatable mRNA for NRF-1 is available. These data suggest that the transcription factor NRF-1 plays a key role in cellular adaptation to energy demands by translating physiological signals into an increased capacity for generating energy.  (+info)

Characterization of the rhodobacter sphaeroides 5-aminolaevulinic acid synthase isoenzymes, HemA and HemT, isolated from recombinant Escherichia coli. (7/369)

The hemA and hemT genes encoding 5-aminolaevulinic acid synthase (ALAS) from the photosynthetic bacterium Rhodobacter sphaeroides, were cloned to allow high expression in Escherichia coli. Both HemA and HemT appeared to be active in vivo as plasmids carrying the respective genes complemented an E. coli hemA strain (glutamyl-tRNA reductase deficient). The over-expressed isoenzymes were isolated and purified to homogeneity. Isolated HemA was soluble and catalytically active whereas HemT was largely insoluble and failed to show any activity ex vivo. Pure HemA was recovered in yields of 5-7 mg x L-1 of starting bacterial culture and pure HemT at 10 mg x L-1 x HemA has a final specific activity of 13 U x mg-1 with 1 unit defined as 1 micromol of 5-aminolaevulinic acid formed per hour at 37 degrees C. The Km values for HemA are 1.9 mM for glycine and 17 microM for succinyl-CoA, with the enzyme showing a turnover number of 430 h-1. In common with other ALASs the recombinant R. sphaeroides HemA requires pyridoxal 5'-phosphate (PLP) as a cofactor for catalysis. Removal of this cofactor resulted in inactive apo-ALAS. Similarly, reduction of the HemA-PLP complex using sodium borohydride led to > 90% inactivation of the enzyme. Ultraviolet-visible spectroscopy with HemA suggested the presence of an aldimine linkage between the enzyme and pyridoxal 5'-phosphate that was not observed when HemT was incubated with the cofactor. HemA was found to be sensitive to reagents that modify histidine, arginine and cysteine amino acid residues and the enzyme was also highly sensitive to tryptic cleavage between Arg151 and Ser152 in the presence or absence of PLP and substrates. Antibodies were raised to both HemA and HemT but the respective antisera were not only found to bind both enzymes but also to cross-react with mouse ALAS, indicating that all of the proteins have conserved epitopes.  (+info)

A photosensitising adenovirus for photodynamic therapy. (8/369)

We have developed a new approach to photodynamic therapy based on adenoviral transduction of the rate-limiting enzyme in heme synthesis. Conventional phototherapy uses porphyrin-based chemical photosensitisers, including delta-aminolaevulinic acid (ALA) which is converted to protoporphyrin IX (PpIX) by the enzymes of the heme biosynthetic pathway. The lack of a specific mechanism for targeting chemical photosensitisers and PpIX to tumour cells means that therapeutic irradiation can damage normal tissue and exposure to sunlight following treatment can cause severe burns. The rate limiting enzyme in PpIX synthesis is ALA-synthase (ALA-S). We have developed a new yeast vector system for manipulation of the adeno- virus genome and used it to construct a virus expressing a mutant form of ALA-S lacking the iron response elements which regulate ALA-S translation and the heme regulatory motifs which regulate import of ALA-S into mitochondria. The virus induces a large increase in PpIX expression and confers photosensitivity on cultured cells. Unlike conventional photodynamic therapy, a viral approach makes it possible to restrict photosensitivity by biological rather than purely physical or chemical means. As with HSV thymidine kinase, ALA-S expression is a general mechanism for sensitisation to a therapeutic agent which can easily be adapted to whatever means of gene delivery is most effective.  (+info)

Effect of endotoxin on tryptophan pyrrolase and delta-aminolaevulinate synthase: evidence for an endogenous regulatory haem...Effect of endotoxin on tryptophan pyrrolase and delta-aminolaevulinate synthase: evidence for an endogenous regulatory haem...
Endotoxin was administered to rats at a dose shown previously to stimulate hepatic haem oxygenase activity and to block induction of delta-aminolaevulinate synthase, apparently by causing redistribution of haem from cytochrome P-450 to a regulatory haem pool in the liver. Within 5h of the administration of endotoxin (at a time when the effect of the compound on cytochrome P-450 is maximal) the relative saturation of tryptophan pyrrolase with intrinsic haem rose, from a basal value of 50% to 90%, indicating that free haem had become available. Concurrently, the activity of delta-aminolaevulinate synthase was decreased to 25% of its basal value. Haem oxygenase reached peak activity 13h after endotoxin administration. These findings provide new evidence for the existence of an unassigned hepatic haem fraction, which exchanges with cytochrome P-450 haem and regulates these three enzyme functions. ...

The activity of 5-aminolaevulinate (ALA) synthase, the first and rate-limiting of haem synthesis, was markedly reduced (13% of controls) in erythroblasts of a patient with acquired, primary sideroblastic anaemia (PASA). The reduced activity of ALA synthase could not be restored in vitro with 1 mmol/l pyridoxal-5-phosphate (PLP). Treatment of the patient with pyridoxine for several months increased the ALA synthase activity from 13% to 50% of controls in the absence and to 100% in the presence of PLP in the incubation medium. These studies suggest that both increased degradation of apo-ALA synthase and decreased affinity of ALA synthase for PLP may be involved in pyridoxine-responsive PASA ...

Aminolevulinic acid synthase - WikipediaAminolevulinic acid synthase - Wikipedia
Aminolevulinic acid synthase (ALA synthase, ALAS, or delta-aminolevulinic acid synthase) is an enzyme (EC 2.3.1.37) that catalyzes the synthesis of D-aminolevulinic acid (ALA) the first common precursor in the biosynthesis of all tetrapyrroles such as hemes, cobalamins and chlorophylls. The reaction is as follows: succinyl-CoA + glycine ⇌ {\displaystyle \rightleftharpoons } δ-aminolevulinic acid + CoA + CO2 This enzyme is expressed in all non-plant eukaryotes and the α-class of proteobacteria. Other organisms produce ALA through a three enzyme pathway known as the Shemin pathway. ALA is synthesized through the condensation of glycine and succinyl-CoA. In humans, transcription of ALA synthase is tightly controlled by the presence of Fe2+-binding elements, to prevent accumulation of porphyrin intermediates in the absence of iron. There are two forms of ALA synthase in the body. One form is expressed in red blood cell precursor cells (ALAS2), whereas the other (ALAS1) is ubiquitously expressed ...

Cultured chick embryo hepatocytes were iron-loaded with ferric nitrilotriacetate. Iron-loading was confirmed by both quantitative cellular iron determinations and ultrastructural studies. With iron-loading, lipid peroxidation, as detected by malonaldehyde released into the medium, occurred at a linear rate for 12h, after which time the rate of malonaldehyde production decreased. No cell toxicity, as detected by lactate dehydrogenase release, was noted. The amount of malonaldehyde recovered in the medium after 18h of exposure to iron represented 24-33% of the total malonaldehyde that could be produced by incubating lysed cells with iron and ascorbate. Cellular glutathione was not affected by iron-stimulated lipid peroxidation, but was increased by allylisopropylacetamide. Although iron-loading by itself had no effect on activity of 5-aminolaevulinate synthase, the first and rate-limiting step in haem synthesis, iron-loading in the presence of the porphyrogenic drug allylisopropylacetamide ...

A 3-month-old boy presented with decreased appetite, fatigue, and a nosebleed. Initial workup revealed hemoglobin 2.6 g/dL (10.2-12.7), hematocrit 7.7% (30.9-37.9), mean corpuscular volume 104 fL (71.3-82.6), white blood cell count 4200/μL (240 absolute neutrophil count), platelets 50 000/μL (140-400), and reticulocyte count 1.31% (1.55-2.7). Bone marrow revealed hypercellularity with cytoplasmic vacuolization of myeloid and erythroid precursors (panels A-B; original magnification ×1000, Wright-Giemsa stain). Iron staining of marrow biopsy revealed numerous ringed sideroblasts (panels C-D; original magnification ×1000, Prussian blue stain). DNA was examined by array-based comparative genomic hybridization and revealed a 4.9-kb deletion, m.11027_15950del4923, consistent with mitochondrial DNA deletion syndrome, also known as Pearson syndrome. Fecal elastase was initially normal, but now it is ,15 μg/g (normal ,200), consistent with severe pancreatic insufficiency. We have begun pancreatic ...

sideroblastic anemiasideroblastic anemia
A decade ago, Brooks McMurrays routine check-up was anything but routine. The suburban Boston boys spleen was enlarged. His red blood cell count was low and the cells were very small and very pale, which suggested a serious iron deficiency anemia. The family pediatrician referred McMurray, now a 19-year-old college freshman, to Dana-Farber/Boston Childrens Cancer and Blood Disorders Center.. There hematologists discovered the boy had unexpectedly high iron levels. Together with pathologist Mark Fleming, MD, DPhil, they solved the mystery. McMurray has congenital sideroblastic anemia, an inherited blood disorder so rare that fewer than 1,000 cases have been reported worldwide. Iron was getting stuck in the wrong place in the precursor red blood cells developing in his bone marrow. …. ...

Erythropoietic porphyria - WikipediaErythropoietic porphyria - Wikipedia
X-linked sideroblastic anemia or X-linked dominant erythropoietic protoporphyria, associated with ALAS2 (aminolevulinic acid synthase), has also been described. X-linked dominant erythropoietic protoporphyria (XDEPP) is caused by a gain of function mutation in the ALAS2 (5-aminolevulinate synthase) gene; that gene encodes the very first enzyme in the heme biosynthetic pathway. The mutation is caused by a frameshift mutation caused by one of two deletions in the ALAS2 exon 11, either c. 1706-1709 delAGTG or c. 1699-1700 delAT. This alters the 19th and 20th residues of the C-terminal domain thereby altering the secondary structure of the enzyme. The delAT mutation only occurred in one family studied whereas the delAGTG mutation occurred in several genetically distinct families. The delAGTG causes a loss of an α-helix which is replaced by a β-sheet. Previously known mutations in the ALAS2 resulted in a loss-of-function mutation causing X-linked sideroblastic anemia. Erythropoietic ...

YARS2 variants have previously been described in patients with myopathy, lactic acidosis and sideroblastic anemia 2 (MLASA2). YARS2 encodes the mitochondrial tyrosyl-tRNA synthetase, which is responsible for conjugating tyrosine to its cognate mt-tRNA for mitochondrial protein synthesis. Here we describe 14 individuals from 11 families presenting with sideroblastic anemia and YARS2 variants that we identified using a sideroblastic anemia gene panel or exome sequencing. The phenotype of these patients ranged from MLASA to isolated congenital sideroblastic anemia. As in previous cases, inter- and intra-familial phenotypic variability was observed, however, this report includes the first cases with isolated sideroblastic anemia and patients with biallelic YARS2 variants that have no clinically ascertainable phenotype. We identified ten novel YARS2 variants and three previously reported variants. In vitro amino-acylation assays of five novel missense variants showed that three had less effect on the ...

ALAS2 gene - Genetics Home Reference - NIHALAS2 gene - Genetics Home Reference - NIH
At least 50 mutations that cause X-linked sideroblastic anemia have been identified in the ALAS2 gene. Almost all of these mutations change single protein building blocks (amino acids) in erythroid ALA-synthase. These changes impair the activity of the enzyme, which disrupts the normal production of heme in developing red blood cells. A reduction in the amount of heme prevents these cells from making enough hemoglobin. Because almost all of the iron transported into erythroblasts is normally incorporated into heme, the reduced production of heme leads to a buildup of excess iron in these cells. Additionally, the body attempts to compensate for the hemoglobin shortage by absorbing more iron from the diet. This buildup of excess iron can damage the bodys organs. Low hemoglobin levels and the resulting accumulation of iron in the bodys organs lead to the characteristic features of X-linked sideroblastic anemia. ...

Hereditary sideroblastic anemia
The essential features of X-linked sideroblastic anemia include the following: (1) a hypochromic microcytic anemia and 2 discrete populations of red blood cells, one microcytic and the other normocytic; (2) marrow ringed sideroblasts, particularly prominent in the late erythroid precursors; (3) a variable hematologic response to pharmacologic doses of pyridoxine; and (4) systemic iron overload secondary to chronic ineffective erythropoiesis. The age of clinical onset of the disorder can vary from in utero to the ninth decade. Whereas males are preferentially affected, females may present with clinically severe anemia. More commonly, female carriers of the disease have an increased red blood cell distribution width and sometimes erythrocyte dimorphism ({18:Fleming, 2002 ...

Lauwerys, R. R., Buchet, J.-P., and Roels, H. A. (1973).British Journal of Industrial Medicine,30, 359-364. Comparative study of effect of inorganic lead and cadmium on blood δ-aminolevulinate dehydratase in man. δ-Aminolevulinate dehydratase (ALA1-D) of red blood cells, lead concentration in blood (Pb-B) and in urine (Pb-U), cadmium concentration in blood (Cd-B) and in urine (Cd-U), and ALA in urine (ALA-U) were measured in 77 workers occupationally exposed to cadmium, and in 73 control workers.. An excellent negative correlation was found between log ALA-D and Pb-B (r = - 0·660) or Pb-U (r = - 0·501), but no significant correlation was found between Cd-B and log ALA-D activity.. Unlike ALA-D, ALA-U is not correlated with Pb and Pb-U in the `normal range of Pb concentration investigated. Mean ALA-D activity in smokers is lower than in nonsmokers, and this is probably related to the fact that a higher mean Pb-B concentration is found in smokers than in nonsmokers..

Alzheimers disease (AD) is a neurodegenerative pathology that affects elderly people all over the world. Several studies have demonstrated that oxidative stress is an aggravating factor for AD development and progression. Therefore, this study aimed to evaluate the activity of two oxidative stress markers, glutathione peroxidase (GPx) and δ -aminolevulinate dehydratase ( δ -ALA-D), as well as correlate them with blood metal levels and AD progression. For this purpose, 88 elderly individuals were divided in two groups: AD group (34 patients diagnosed with AD) and control group (34 subjects paired by age with the AD group). The Mini-Mental State Examination and the Clinical Dementia Rating (CDR ) were used as tools to classify the AD progression. GPx and δ -ALA-D activities were measured in all subjects through blood tests. Both enzymes activities were decreased in AD patients when compared to the age-matched control group, regardless of the CDR. Moreover, GPx activity was positively ...

British Library EThOS: Structure and function of tetrapyrrole biosynthesis enzymes: ALA synthase and cobalt chelataseBritish Library EThOS: Structure and function of tetrapyrrole biosynthesis enzymes: ALA synthase and cobalt chelatase
Modified tetrapyrroles are versatile compounds that are universally utilized by enzymes as co-factors in a myriad of enzyme cata lyzed reaction s. Examples include heme, the cofactor of hemoglobin and myoglobin, that carries and stores molecular oxygen in the blood and muscle respectively, and cobalamin a cofactor that is synthesized by prokaryotes and which is an important nutrient for humans. This work focuses on the enzymatic mechanism of metal chelation and in particular on the structural characterization of the cobalt-chelatases CbiK from Salmonella enterica and CbiX from Archaeoglobus /u/gidus that take part in the biosynthesis of cobalamin. Crystal structures of the enzyme-tetrapyrrole complex were obtained that reveal radically different modes of binding compared to the well characterized ferrochelatases. Furthermore protein structures reveal the evolutionary re lationships between cobaltochelatases from different organisms. The second part of this thesis is focusing on 5-aminolevulinic ...

Basal cell carcinoma (BCC) is the most common cancer affecting Caucasians and, due to its large size or to the poor condition of the patient, it can be difficult to treat it with conventional therapies: in these cases photodynamic therapy with methyl aminolevulinate (MAL-PDT) may represent a good option. A retrospective non-comparative follow-up study was performed to test the response of giant and large BCC to MAL-PDT. Twelve patients with 14 giant BCC (≥ 5 cm) and 5 patients with 5 large BCC (4-5 cm) were treated with MAL-PDT; they were evaluated 6 months after the end of the treatment to define the initial cure rate, and then at 12 and 36 months for the follow-up. At 6 months the initial cure rate for the 19 BCCs was 95% and at 36 months the overall long-term cure rate was 66%. The follow-up will last up to 5 years. MAL-PDT is a valid option for the treatment of giant and large BCC ...

Acute intermittent porphyria is a type of acute hepatic porphyria that usually presents with gastrointestinal, neurological, and psychiatric symptoms. The common clinical manifestations of this condition include severe abdominal pain accompanied with nausea, vomiting, and ileus; and neurological symptoms, such as seizure, PRES, chronic neuropathic pain, psychosis, and motor-dominant polyneuropathy [5,6]. It is well known that antiepileptic medications, which induce hepatic cytochrome P450 enzymes, act as exacerbating factors of AIP, as do etomidate, ketamine, NSAIDs, and rifampin. Glucose acts as a suppressor of delta-aminolaevulinic acid synthase expression, which participates in the heme biosynthetic pathway.

Givosiran is a N-acetylgalactosamine (GalNAc)-conjugated RNA interference (RNAi) therapeutic that targets 5ʹ-aminolevulinate synthase 1 (ALAS1) messenger RNA (mRNA) in the liver and is currently marketed for the treatment of acute hepatic porphyria (AHP). Herein, nonclinical pharmacokinetic (PK) and absorption, distribution, metabolism, and excretion (ADME) properties of givosiran were characterized. Givosiran was completely absorbed after subcutaneous (SC) administration with relatively short plasma elimination t1/2 (less than 4 hours). Plasma exposure increased approximately dose proportionally with no accumulation after repeat doses. Plasma protein binding (PPB) was concentration dependent across all species tested and was around 90% at clinically relevant concentration in human. Givosiran predominantly distributed to the liver by asialoglycoprotein receptor (ASGPR)-mediated uptake, and the elimination t1/2 in the liver was significantly longer (~1 week). Givosiran was metabolized by ...

Primary acquired sideroblastic erythropoiesis in non-anaemic and minimally anaemic subjects. | Journal of Clinical PathologyPrimary acquired sideroblastic erythropoiesis in non-anaemic and minimally anaemic subjects. | Journal of Clinical Pathology
Six patients had primary sideroblastic erythropoiesis together with a haemoglobin concentration of 12.0 g/dl or higher. In four cases this was associated with macrocytosis. Other abnormalities included failure of erythroid progenitor growth from peripheral blood in three cases and occasional dysplastic appearances in neutrophils and megakaryocytes. Sideroblastic erythropoiesis seems to be an early manifestation of the myelodysplastic syndrome and may present clinically at a pre-anaemic stage.. ...

The pathophysiology of myelodysplasia is complex. There is evidence for impairments in stem cell growth, progenitor maturation, and both growth factor production and progenitor responsiveness. The presence of ineffective hematopoiesis (increased apoptosis of maturing marrow precursors) is a hallmark of myelodysplasia. It appears to correlate in part with CD95 expression and persistent high levels of Fas receptor, resulting in increased fas-ligand apoptosis. Upregulation of the cytokines tumor necrosis factor α (TNF-α) and interleukin 1β (IL-1β) also may play a role in promoting apoptosis of long-term hematopoietic stem cells (LT-HSC) and committed precursors in myelodysplastic marrows. Vascular endothelial growth factor (VEGF) overproduction is thought to be involved in the promotion of myeloblastic elements, and perhaps the evolution to acute myeloid leukemia (AML). ...

  • We have measured the transcriptional gene activity of 5-aminolevulinate synthase, the first enzyme of the heme biosynthetic pathway, together with corresponding mRNA and protein levels in mouse erythroleukemic cells induced to differentiate with dimethyl sulfoxide. (utmb.edu)
  • When the heme biosynthetic pathway was blocked by succinylacetone there was a large increase in both 5-aminolevulinate synthase activity and protein levels, and this was reversed by the addition of exogenous hemin. (utmb.edu)
  • Transcriptional activity of the 5-aminolevulinate synthase gene and mRNA levels were both significantly increased during differentiation of cells by dimethyl sulfoxide but were not markedly altered by succinylacetone or hemin treatment. (utmb.edu)
  • The results demonstrate that levels of 5-aminolevulinate synthase in mouse erythroleukemic cells are regulated by a significant post-transcriptional mechanism possibly at the translational level. (utmb.edu)
  • Evidence is also presented for a less significant post-transcriptional control by heme of mRNA levels for 5-aminolevulinate synthase. (utmb.edu)
  • These results indicate that the regulation of 5-aminolevulinate synthase in differentiating erythroid cells is complex but differs from that in liver cells where heme controls to level of 5-aminolevulinate synthase by acting primarily to inhibit gene transcription. (utmb.edu)
