Oxidized derivatives of 7-dehydrocholesterol induce growth retardation in cultured rat embryos: a model for antenatal growth retardation in the Smith-Lemli-Opitz syndrome. (1/122)

7-Dehydrocholesterol accumulates in fetuses affected by the Smith-Lemli-Opitz syndrome as a result of a deficit in the ultimate step of cholesterol synthesis catalyzed by Delta7 reductase. Rat embryos explanted at gestation day 10 and cultured for 48 h in the presence of the Delta7 reductase inhibitor AY 9944 were used as a model to discriminate between the beneficial effect of supplementation with cholesterol and the deleterious effect of supplementation with 7-dehydrocholesterol. Cholesterol supplementation in the form of mixed cholesterol/lecithin liposomes added to serum serving as the culture medium restores the growth of embryos which is markedly decreased in the presence of the inhibitor. 7-Dehydrocholesterol under identical conditions does not restore growth and impairs the beneficial effect of cholesterol added simultaneously. UV-photooxidation of 7-dehydrocholesterol-supplemented culture medium enhances its embryotoxicity, which suggests uptake by the embryo of toxic by-products formed from 7-dehydrocholesterol. By contrast photooxidation of cholesterol-supplemented culture medium does not induce embryotoxicity. alpha-Tocopherol reduces the toxicity of photooxidized 7-dehydrocholesterol supplementing the culture medium. We conclude that 7-dehydrocholesterol does not fulfill the cholesterol requirement of the developing embryos and exerts an additional embryotoxic effect probably via oxidized by-products. This could explain the antenatal growth retardation of SLOS by a blockage of the maternal compensatory cholesterol influx.  (+info)

The Opitz syndrome gene product, MID1, associates with microtubules. (2/122)

Opitz syndrome (OS) is a genetically heterogeneous disorder characterized by defects of the ventral midline, including hypertelorism, cleft lip and palate, heart defects, and mental retardation. We recently identified the gene responsible for X-linked OS. The ubiquitously expressed gene product, MID1, is a member of the RING finger family. These proteins are characterized by an N-terminal tripartite protein-protein interaction domain and a conserved C terminus of unknown function. Unlike other RING finger proteins for which diverse cellular functions have been proposed, the function of MID1 is as yet undefined. By using the green fluorescent protein as a tag, we show here that MID1 is a microtubule-associated protein that influences microtubule dynamics in MID1-overexpressing cells. We confirm this observation by demonstrating a colocalization of MID1 and tubulin in subcellular fractions and the association of endogenous MID1 with microtubules after in vitro assembly. Furthermore, overexpressed MID1 proteins harboring mutations described in OS patients lack the capability to associate with microtubules, forming cytoplasmic clumps instead. These data give an idea of the possible molecular pathomechanism underlying the OS phenotype.  (+info)

Cholesterol biosynthesis from lanosterol. Molecular cloning, tissue distribution, expression, chromosomal localization, and regulation of rat 7-dehydrocholesterol reductase, a Smith-Lemli-Opitz syndrome-related protein. (3/122)

The cDNA encoding the 471-amino acid rat 7-dehydrocholesterol reductase (DHCR), an enzyme that has been implicated in both cholesterol biosynthesis and developmental abnormalities (e.g. Smith-Lemli-Opitz syndrome) in mammals, has been cloned and sequenced, and the primary structure of the enzyme has been deduced. The DHCR gene was mapped to chromosome 8q2.1 by fluorescence in situ hybridization. Rat DHCR, calculated molecular mass of 54.15-kDa polypeptide, shares a close amino acid identity with mouse and human DHCRs (96 and 87%, respectively) as compared with its other related proteins (e.g. fungal sterol Delta14-reductase) and exhibits high hydrophobicity (>68%) with 9 transmembrane domains. Five putative sterol-sensing domains were predicted to be localized in transmembrane domains 4-8, which are highly homologous to those found in 3-hydroxymethylglutaryl-CoA reductase, sterol regulatory element-binding protein cleavage-activating protein, and patched protein. The polypeptide encoded by DHCR cDNA was expressed in yeast as a 55.45-kDa myc-tagged fusion protein, which was recognized with anti-myc monoclonal antibody 9E10 and shown to possess full DHCR activity with respect to dependence on NADPH and sensitivity to DHCR inhibitors. Northern blot analysis indicates that the highest expression of DHCR mRNA was detected in liver, followed by kidney and brain. In rat brains, the highest level of mRNA encoding DHCR was detected in the midbrain, followed by the spinal cord and medulla. Feeding rats 5% cholestyramine plus 0.1% lovastatin in chow resulted in both approximately a 3-fold induction of DHCR mRNA and a 5-fold increase of the enzymic activity in the liver. When rats were fed 0.1% (w/w) AY-9944 (in chow) for 14-days, a complete inhibition of DHCR activity and a significant reduction in serum total cholesterol level were observed. However, the level of hepatic DHCR mRNA fell only slightly, suggesting that AY-9944 may act more rapidly at the protein level than at the level of transcription of the DHCR gene under these conditions.  (+info)

Marked alteration of sterol metabolism and composition without compromising retinal development or function. (4/122)

PURPOSE: To evaluate the consequences of altering retinal sterol metabolism and composition on the development, histologic organization, and electrophysiological function of the retina, under conditions that mimic the biochemical hallmarks of the Smith-Lemli-Opitz (SLO) syndrome. METHODS: Pregnant Sprague-Dawley rats were fed cholesterol-free chow containing AY9944 (treated group), an inhibitor of 3beta-hydroxysterol delta7-reductase, from gestational day 6 through postnatal day (P)28. Control animals were fed the same chow, but without AY9944. In addition, progeny in the treated group were injected subcutaneously every other day from birth to P28 with an olive oil emulsion containing AY9944; control animals received olive oil emulsion alone. At various postnatal times, tissues from treated and control animals were harvested, and their sterol profiles were analyzed by reversed-phase high-performance liquid chromatography. Companion eyes from animals of both groups were examined histologically at P1. At P28, animals were evaluated by electroretinography; tissues were then harvested for biochemical analysis and companion eyes were subjected to histologic and ultrastructural analyses. RESULTS: Treatment of developing rats with AY9944 caused markedly abnormal accumulation of 7-dehydrosterols and severely reduced cholesterol levels in all tissues examined, relative to control animals. Despite this, treated animals exhibited normal retinal development and had no overt ocular defects or decrease in electroretinographic function, up to P28. CONCLUSIONS: These results were unexpected, given the known biophysical effects of such sterol alterations on membrane properties and the profound dysmorphic and cognitive abnormalities associated with genetic defects in 3beta-hydroxysterol delta7-reductase that have been linked to the SLO syndrome. The results suggest that 7-dehydrosterols can substitute functionally for cholesterol in the retina or perhaps can act synergistically with subthreshold levels of residual cholesterol to allow normal cellular structure and function to be achieved.  (+info)

Functional characterization of the Opitz syndrome gene product (midin): evidence for homodimerization and association with microtubules throughout the cell cycle. (5/122)

Opitz syndrome (OS) is a multiple congenital anomaly manifested by abnormal closure of midline structures. The gene responsible for the X-linked form of this disease, MID1, encodes a protein (midin) that contains a RING, two B-boxes, a coiled-coil (the so-called tripartite motif) and an RFP-like domain. The tripartite motif is characteristic of a family of proteins, named the B-box family, involved in cell proliferation and development. Since the subcellular compartmentalization and the ability to form multiprotein structures both appear to be crucial for the function of this family of proteins, we have studied these properties on the wild-type and mutated forms of midin. We found that endogenous midin is associated with microtubules throughout the cell cycle, co-localizing with cytoplasmic fibres in interphase and with the mitotic spindle and midbodies during mitosis and cytokinesis. Immunoprecipitation experiments demonstrated the ability of the tripartite motif to mediate midin homodimerization, consistent with the evidence, obtained by gel filtration analysis, that midin exists in the form of large protein complexes. Functional characterization of altered forms of midin, resulting from mutations found in OS patients, revealed that association with microtubules is compromised, while the ability to homodimerize and form multiprotein complexes is retained. We suggest that midin is involved in the formation of multiprotein structures acting as anchor points to microtubules and that impaired association with these cytoskeletal structures causes OS developmental defects.  (+info)

MID2, a homologue of the Opitz syndrome gene MID1: similarities in subcellular localization and differences in expression during development. (6/122)

The B-box family is an expanding new family of genes encoding proteins involved in diverse cellular functions such as developmental patterning and oncogenesis. A member of this protein family, MID1, is the gene responsible for the X-linked form of Opitz G/BBB syndrome, a developmental disorder characterized by defects of the midline structures. We now report the identification of MID2, a new transcript closely related to MID1. MID2 maps to Xq22 in human and to the syntenic region on the mouse X chromosome. The two X-linked genes share the same domains, the same exon-intron organization, a high degree of similarity at the protein level and the same subcellular localization, both being confined to the cytoplasm in association to micro-tubular structures. The expression pattern studied by RNA in situ hybridization in mouse revealed that Mid2 is expressed early in development and the highest level of expression is detected in the heart, unlike Mid1 for which no expression was detected in the developing heart. Together, these data suggest that midin and MID2 have a similar biochemical function but a different physiological role during development.  (+info)

Bile acid synthesis in the Smith-Lemli-Opitz syndrome: effects of dehydrocholesterols on cholesterol 7alpha-hydroxylase and 27-hydroxylase activities in rat liver. (7/122)

The Smith-Lemli-Opitz syndrome (SLOS) is a congenital birth defect syndrome caused by a deficiency of 3beta-hydroxysterol Delta(7)-reductase, the final enzyme in the cholesterol biosynthetic pathway. The patients have reduced plasma and tissue cholesterol concentrations with the accumulation of 7-dehydrocholesterol and 8-dehydrocholesterol. Bile acid synthesis is reduced and unnatural cholenoic and cholestenoic acids have been identified in some SLOS patients. To explore the mechanism of the abnormal bile acid production, the activities of key enzymes in classic and alternative bile acid biosynthetic pathways (microsomal cholesterol 7alpha-hydroxylase and mitochondrial sterol 27-hydroxylase) were measured in liver biopsy specimens from two mildly affected SLOS patients. The effects of 7- and 8-dehydrocholesterols on these two enzyme activities were studied by using liver from SLOS model rats that were treated with the Delta(7)-reductase inhibitor (BM15.766) for 4 months and were comparable with more severe SLOS phenotype in plasma and hepatic sterol compositions. In the SLOS patients, cholesterol 7alpha-hydroxylase and sterol 27-hydroxylase were not defective. In BM15.766-treated rats, both enzyme activities were lower than those in control rats and they were competitively inhibited by 7- and 8-dehydrocholesterols. Rat microsomal cholesterol 7alpha-hydroxylase did not transform 7-dehydrocholesterol or 8-dehydrocholesterol into 7alpha-hydroxylated sterols. In contrast, rat mitochondrial sterol 27-hydroxylase catalyzed 27-hydroxylation of 7- and 8-dehydrocholesterols, which were partially converted to 3beta-hydroxycholestadienoic acids. Addition of microsomes to the mitochondrial 27-hydroxylase assay mixture reduced 27-hydroxydehydrocholesterol concentrations, which suggested that 27-hydroxydehydrocholesterols were further metabolized by microsomal enzymes. These results suggest that reduced normal bile acid production is characteristic of severe SLOS phenotype and is caused not only by depletion of hepatic cholesterol but also by competitive inhibition of cholesterol 7alpha-hydroxylase and sterol 27-hydroxylase activities by accumulated 7- and 8-dehydrocholesterols. Unnatural bile acids are synthesized mainly by the alternative pathway via mitochondrial sterol 27-hydroxylase in SLOS.  (+info)

Smith-Lemli-Opitz syndrome: a treatable inherited error of metabolism causing mental retardation. (8/122)

Smith-Lemli-Opitz syndrome, a syndrome of multiple malformations and mental retardation that for years was relegated to the atlases of genetic esoterica, was recently found to be a relatively common inborn error of metabolism. The underlying defect is absent or deficient activity of 7-dehydrocholesterol- delta 7-reductase, the enzyme catalysing the final step of cholesterol synthesis. The discovery of the biochemical defect causing Smith-Lemli-Opitz syndrome has resulted in the development of a diagnostic test and a potentially beneficial treatment (dietary cholesterol supplementation). Infants and young children with the syndrome have shown marked improvement in growth, behaviour and general health after receiving cholesterol therapy; older children and adults have shown some improvement in development and intellectual functioning. Despite the excitement these developments have elicited among geneticists and biochemists, this syndrome remains relatively unknown to many primary care physicians. Increased awareness of Smith-Lemli-Opitz syndrome is needed to identify affected patients so that they and their families can benefit from appropriate treatment and genetic counselling.  (+info)

Smith-Lemli-Opitz syndrome (SLOS) is a severe autosomal recessive disorder resulting from defects in the cholesterol synthesising enzyme 7-dehydrocholesterol reductase (Δ7-sterol reductase, DHCR7, EC 1.3.1.21) leading to a build-up of the cholesterol precursor 7-dehydrocholesterol (7-DHC) in tissues and blood plasma. Although the underling enzyme deficiency associated with SLOS is clear there are likely to be multiple mechanisms responsible for SLOS pathology. In an effort to learn more of the aetiology of SLOS we have analysed plasma from SLOS patients to search for metabolites derived from 7-DHC which may be responsible for some of the pathology. We have identified a novel hydroxy-8-dehydrocholesterol, which is either 24- or 25-hydroxy-8-dehydrocholesterol and also the known metabolites 26-hydroxy-8-dehydrocholesterol, 4-hydroxy-7-dehydrocholesterol, 3β,5α-dihydroxycholest-7-en-6-one and 7α,8α-epoxycholesterol. None of these metabolites are detected in control plasma at quantifiable ...
Smith-Lemli-Opitz Syndrome (SLOS) is an autosomal recessive disorder caused by a metabolic error in the final step of cholesterol biosynthesis, leading to cholesterol deficiency and accumulation of the cholesterol precursor, 7-dehydrocholesterol.Patients with SLOS display complex medical problems including growth failure, intellectual disability, behavioral disorders, progressive retinal dystrophy, hearing loss and photosensitivity. Dr Elias was one of the original geneticists who discovered the cause of this disorder in 1994, and ever since has been treating SLOS patients with cholesterol supplementation. Since 2008, a second medication called AquADEKS, a mixture of vitamins and other compounds with antioxidant properties was added to the treatment regimen. The purpose of the AquADEKS is to allow treatment with antioxidant medications in an effort to prevent retinal degeneration, hearing and skin problems associated with SLOS.. This protocol has been approved by the Colorado Multiple ...
Smith-Lemli-Opitz syndrome (SLOS) is an autosomal recessive multiple congenital anomaly/mental retardation syndrome. Typical clinical features include a distinctive facial appearance, mental retardation, autistic behavior, hypotonia, failure to feed, poor growth, decreased life span, and variable structural anomalies of the heart, lungs, brain, gastrointestinal tract, limbs, genitalia and kidneys. The SLOS phenotypic spectrum is broad and variable. At the severe end of the spectrum SLOS is a lethal disorder with multiple major congenital anomalies; whereas, mild cases of SLOS present with a combination of minor physical stigmata, behavioral problems, and learning disabilities. SLOS is due to an inborn error of cholesterol biosynthesis. Biochemically, SLOS patients have a deficiency of 3beta-hydroxysterol delta(7)-reductase activity. 3beta-hydroxysterol delta(7)-reductase is an NADPH dependent microsomal enzyme that catalyzes the reduction of the C7(8) double bond of 7-dehydrocholesterol (7-DHC) ...
This abstract was presented today at the Association for Research in Vision and Opthalmology (ARVO) meetings in Seattle, Washington by Steven J. Fliesler, Christopher C. Goulah, W. Drew Ferrell, Robert E. Marc and Bryan W. Jones.. Purpose: Smith-Lemli-Opitz syndrome (SLOS) is a developmental disorder involving defective cholesterol biosynthesis. Prior studies using a rat model of SLOS have documented progressive retinal dysfunction and degeneration, apparently involving caspase-3-independent cell death of photoreceptors. Retinal remodeling has been documented in human retinal degenerations and a myriad of animal models of retinal disease (Jpn J Ophthalmol. 56(4):289, 2012). Here, we examined retinal degeneration and remodeling in the SLOS rat model vs. age-matched control rats.. Methods: A pharmacologically-induced rat model of SLOS was generated by treating Sprague-Dawley rats with AY9944 (Arch. Ophthalmol. 122:1190, 2004). At 81 days postnatal (P81), eyes from AY9944-treated and control rats ...
Smith-Lemli-Opitz syndrome (SLOS, OMIM 270400) is an autosomal recessive disorder of cholesterol biosynthesis resulting from deficient 3β-hydroxysterol Δ7-reductase (DHCR7) activity.1,2 Patients with SLOS have a characteristic facial phenotype, various degrees of cleft palate and of syndactyly of toes 2 and 3, failure to thrive, behavioural problems, and mental retardation in addition to variable combinations of external and internal malformations.3-5 The spectrum of severity extends from prenatal death with holoprosencephaly or other lethal malformations to minimally physically affected patients with normal intelligence or minimal intellectual impairment. Most patients with SLOS have abnormally low levels of plasma cholesterol and all have raised levels of its immediate precursor, 7-dehydrocholesterol (7DHC).2. The DHCR7 gene has been mapped to chromosome 11q13, spans approximately 14 kb, and encodes a protein of 475 amino acid residues.6 To date, 85 different DHCR7 mutations have been ...

Smith Lemli Opitz syndrome (SLOS) is a 46,XY disorder of sex development, included in the subgroup of disorders in androgene synthesis. The disease is caused by mutations of 7-dehydrocholesterol reductase (DHCR7) gene, conducting to deficient synthesis of the correspondent enzyme and of cholesterol, with important role in embryogenesis, adrenal and gonadal steroidogenesis. Clinical manifestations includ facial dysmorphism, syndactyly, ambiguous external genitalia and visceral malformations.. We present the case of an infant born by cesarean section for fetal suffering (Apgar score 8/1′ 8/5′), with multiple malformations (dysmorphic face, polydactyly, syndactyly, hypospadias, cryptorchidism) detected already at birth. Investigations diagnosed small atrial septal defect and corpus callosum agenesis was suspected. The clinical examination at 4 months of age showed growth failure, dysmorphic face, bilateral ptosis and epicantus, generalized muscle hypotony, asymmetrical polydactyly (complete on ...
We investigated the enzyme defect in late cholesterol biosynthesis in the Smith-Lemli-Opitz syndrome, a recessively inherited developmental disorder characterized by facial dysmorphism, mental retardation, and multiple organ congenital anomalies. Reduced plasma and tissue cholesterol with increased 7-dehydrocholesterol concentrations are biochemical features diagnostic of the inherited enzyme defect. Using isotope incorporation assays, we measured the transformation of the precursors, [3 alpha- 3H]lathosterol and [1,2-3H]7-dehydrocholesterol into cholesterol by liver microsomes from seven controls and four Smith-Lemli-Opitz homozygous subjects. The introduction of the double bond in lathosterol at C-5[6] to form 7-dehydrocholesterol that is catalyzed by lathosterol-5-dehydrogenase was equally rapid in controls and homozygotes liver microsomes (120 +/- 8 vs 100 +/- 7 pmol/mg protein per min, P = NS). In distinction, the reduction of the double bond at C-7 [8] in 7-dehydrocholesterol to yield ...

This gene encodes an enzyme that removes the C(7-8) double bond in the B ring of sterols and catalyzes the conversion of 7-dehydrocholesterol to cholesterol. This gene is ubiquitously expressed and its transmembrane protein localizes to the endoplasmic reticulum membrane and nuclear outer membrane. Mutations in this gene cause Smith-Lemli-Opitz syndrome (SLOS); a syndrome that is metabolically characterized by reduced serum cholesterol levels and elevated serum 7-dehydrocholesterol levels and phenotypically characterized by cognitive disability, facial dysmorphism, syndactyly of second and third toes, and holoprosencephaly in severe cases to minimal physical abnormalities and near-normal intelligence in mild cases. Alternative splicing results in multiple transcript variants that encode the same protein.[provided by RefSeq, Aug 2009 ...

Smith-Lemli-Opitz Syndrome (SLOS) is a genetic disorder (autosomal recessive) caused by an abnormality in the production of cholesterol. The disorder can occur in both a mild or severe form. SLOS is associated with multiple birth defects and mental retardation. Some of the birth defects include; abnormal facial features, poor muscle tone, poor growth, shortened life span, and abnormalities of the heart, lungs, brain, gastrointestinal tract, limbs, genitalia, and kidneys. There is no known cure for SLOS but recently patients have been treated with increased amounts of cholesterol in their diet. The cholesterol in a persons diet is unable to correct the abnormalities in the patients organs, but researchers hope it will improve growth failure and mental retardation.

The study will enroll patients diagnosed with SLOS, and their mothers. The objectives ...
Smith-Lemli-Opitz syndrome is a hereditary developmental disorder. It is characterized by nostrils that tilt forward (anteverted nares), drooping eyelids, webbing between the second and third toes, male genital abnormalities, mental retardation, and small stature.
Minor aberrant pathways of cholesterol biosynthesis normally produce only trace levels of abnormal sterol metabolites but may assume major importance when an essential biosynthetic step is blocked. Cholesta-5,8-dien-3beta-ol, its Delta(5,7) isomer, and other noncholesterol sterols accumulate in subjects with the Smith-Lemli-Opitz syndrome (SLOS), a severe developmental disorder caused by a ...
BUFFALO, N.Y. - A new study led by vision researchers at the Jacobs School of Medicine and Biomedical Sciences at the University at Buffalo and VA Western New York Healthcare System has demonstrated that the addition of widely available antioxidants to the current standard-of-care prevented vision loss in an animal model of a rare genetic disease.. Published in the Jan. 19 issue of Scientific Reports, the paper describes the combination therapy that resulted in preventing the retinal degeneration that can occur in babies born with Smith-Lemli-Opitz Syndrome (SLOS).. Caused by the bodys inability to make cholesterol, the disease is a birth defect that results in multiple neurosensory and cognitive abnormalities, physical deformities and disabilities, including vision loss. In severe cases, it can be fatal.. Using our combination therapy approach, we were able to prevent otherwise progressive and irreversible retinal degeneration from occurring in a rodent model of this hereditary human ...
The first month in the hospital was a waiting game - genetics tests had been sent out but would take quite a while to get back. In the meantime docs threw out several syndrome names they were trying to rule out. After CHARGE, it was Smith-Lemli-Opitz and Simpson-Golabi-Behmel. We wondered about Rubenstein-Taybi Syndrome because of all his hair. But nothing really fit him completely. Then came the basic chromosome test to tell us if his karyotype (if the number of his chromosomes) was the normal 46. It was - 46, XY, which we were thrilled to hear! The microarray, a more detailed analysis of the genes on each chromosome, took the longest. Even after the results came back we had to wait until the geneticist researched the results to be able to tell us what they meant. At about 3:20 pm on Sept. 21, a month and 2 days after he was born, the geneticist sat us down and told us what Mason had... a deletion of 14 genes at chromosome 17p13.2. There is a syndrome near this area of genes, at 17p13.3, that ...

Holoprosencephaly (HPE) is the most common structural malformation of the developing forebrain in humans and is typically characterized by different degrees of hemispheric separation that are often accompanied by similarly variable degrees of craniofacial and midline anomalies. HPE is a classic example of a complex genetic trait with pseudo-autosomal dominant transmission showing incomplete penetrance and variable expressivity. Clinical suspicion of HPE is typically based upon compatible craniofacial findings, the presence of developmental delay or seizures, or specific endocrinological abnormalities, and is then followed up by confirmation with brain imaging. Once a clinical diagnosis is made, a thorough genetic evaluation is necessary. This usually includes analysis of chromosomes by high-resolution karyotyping, clinical assessment to rule-out well recognized syndromes that are associated with HPE (e.g., Pallister-Hall syndrome, Smith-Lemli-Opitz syndrome and others), and molecular studies of the
Chief Technologist: Éva Kálmánchey Gombos. TThe Molecular Pathology division of the department was established in 1995. At the beginning the DNA analysis panel of severe inherited disorders was introduced, which was extended with the analysis of different genetic risk factors and pharmacogenetic testing. The division provides genetic testing in three main areas:. 1. Molecular genetic analysis of severe inherited diseases (cystic fibrosis, Duchenne/Becker muscular dystrophy, hemochromatosis, Smith-Lemli-Opitz syndrome, Niemann-Pick disease type C, autosomal recessive polycystic kidney disease, MODY, neonatal diabetes, etc).. 2. Molecular genetic analysis of inherited risk factors predisposing to different multifactorial diseases (thrombosis risk factors, hyperlipidemic risk factors).. 3. Pharmacogenetic testing (CYP2C9, TPMT, UGT1A1, VKORC1). In the routine diagnostic procedures a number of different methods are used (blotting techniques, allele-specific PCR, fluorescent real-time PCR methods, ...
This book represents a revision of a 2004 edition called Demystifying Syndromes. In Demystifying Syndromes II, the editors have selected some common and some lesser known syndromes that are associated with persons with developmental disabilities and coexisting mental or behavioral challenges, specifically Autism Spectrum Disorders, as well as Fragile X, Down, Williams, Smith-Magenis, 22q Deletion, Smith-Lemli-Opitz, and Angelman syndromes.. Each book chapter provides the reader with an informative and accurate description of the disability, written by individuals with an integrated understanding of how the physical, psychiatric or biochemical influences may interact with the psychological factors (learning approaches, communication, skills) of the individual, as well as with the social-environmental aspects (supports, adaptations, and vulnerabilities). The authors have not merely focused on the challenges presented by the syndrome, but the strengths and resiliency that each syndrome presents. ...

The tumor microenvironment may play a crucial role in tumor progression metastasis and invasion. immunohistochemistry and review. The increased loss of appearance of E-cadherin was even more prominent in the intrusive front side of tumor compared to the surface area where PF299804 α-even muscles actin-positive carcinoma-associated fibroblasts (CAFs) are gathered. The signaling substances from the Wnt and TGF-β1-Smad pathway had been expressed more often in the tumor cells and/or CAFs from the intrusive margin than those from the tumor surface area. The expressions of related transcription elements such as for example SNAIL and ZEB1 had been elevated in the tumor cells and CAFs. The procedure of EMT may be activated in the tumor margin of CRC beneath the control of CAFs. Related signaling transcription and molecules points may be induced by paracrine ramifications of the encompassing CAFs. [36] reported that huge aggregates of CRC cells (much bigger than tumor buds) induced matrix degradation ...

Regulated, stimulus-dependent secretion via the exocytosis of dense core granule content provides a mechanism for controlling delivery of hormones, enzymes, neuropeptides, and neurotransmitters to a target cell or organ in a timely and quantified manner (Burgoyne and Morgan, 2003; Loh et al., 2004; Lou et al., 2005). In this study, we have investigated the contributions of cholesterol, 7-DHC and lathosterol to granule biogenesis and regulated secretion in exocrine and endocrine tissues of mouse models of SLOS and lathosterolosis. We report here that cholesterol is necessary for the correct formation of granules in vivo. In the formation of regulated secretory vesicles in animals with inborn errors of cholesterol synthesis, cholesterol cannot be substituted by other lipids with structural similarity. We also show deregulated secretion of cargo in acinar cells of the exocrine pancreas, owing to the absence of cholesterol, which suggests impairment of cellular function.. It has been reported that ...

Results: We selected 127 patients (GT2 n = 50, GT3 n = 77), 50% cirrhotic patients, and 42% who experienced a virological relapse. At baseline, GT3 patients had lower level of serum lipids, apoB/E, 7-dehydrocholesterol, desmosterol, lathosterol, compared to GT2 (p ,0.006). Baseline lathosterol was lower in relapsers with cirrhosis compared to cirrhotic patients with SVR (p = 0.003). From baseline to treatment week 12, serum lipids, apoB/E, and key sterol pathway metabolites (7-dehydrocholesterol, desmosterol, lathosterol, lanosterol) increased in GT3. In contrast, in GT2 patients, apoB/E and dihydrolanosterol decreased with viral suppression (p ,0.025). At follow-up week 4, cirrhotic SVR patients showed substantially greater increases in apoB and total sterols compared to cirrhotic relapsers regardless of HCV genotype. After adjustment for genotype and gender, baseline lathosterol was independently associated with virologic response (p = 0.04 ...
Hundreds of loci have been robustly associated with circulating lipids, atherosclerosis and coronary artery disease; but for most loci the causal genes and mechanisms remain uncharacterized. The overall aim of my thesis is to develop and validate novel in vivo model systems that are suitable for high-throughput, image-based genetic screens in coronary artery disease and related traits, and use these model systems to systematically characterize positional candidate genes.. In Study I, I developed an experimental pipeline to validate the suitability of zebrafish larvae as a model system for systematic, large-scale characterization of drugs and genes associated with dyslipidemia and atherosclerosis. Using this pipeline, I showed that five days of overfeeding and cholesterol supplementation have independent pro-atherogenic effects in zebrafish larvae, which could be diminished by concomitant treatment with atorvastatin and ezetimibe.
