اسکیزوفرنی یک بیماری چند عاملی و پیچیده روانی است که هنوز به خوبی درک نشده است. آسیب اکسیداتیو به عنوان یک فاکتور مهم در پیداش و پیشرفت تعداد زیادی از بیماری ها از جمله اسکیزوفرنیا نقش دارد. آنزیم کاتالاز (cat) از جمله آنزیم های آنتی اکسیدان است، که از سلولها در برابر آسیب اکسیداتیو محافظت می کند. هدف از این مطالعه، بررسی ارتباط چند شکلی ژنتیکی cat c-262t با خطر ابتلا به اسکیزوفرنیا می باشد. در...
this is the first description of the polymorphisms of arylalkylamine-n-acetyltransferase (aa-nat) gene in indian goats with different reproductive traits (twinning percentage and age of sexual maturity). based on the important role of aa-nat in reproduction, it is considered as a possible candidate gene for this trait. two novel synonymous snps, c825t (exon2) and c1249t (exon3) were identified....
more than 80% of the total milk protein contains caseins that are to forms α-s1, α-s2, β-casein and kappa casein. kappa casein is smaller than other milk proteins but due to have a role in size and stability of micelles. the present study describes polymorphism of kappa casein gene. this is the first study of kappa casein gene polymorphism in najdi cattle of iran. we used the polymerase chain r...
Background and Aim: Cytokines are believed to play an important role in the regulation of cellular immune response in hepatitis B virus infection. Interleukin 10 is a member of cytokine family. The overall expression of these molecules is mainly controlled by single nucleotide polymorphisms at specific sites on the promoter region of the Interleukin 10 gene. The aim of this study was to a...
Association of rs1800624 Polymorphism in Receptor for Advanced Glycation End Products Gene Promoter with the Risk Diabetic Nephropathy
Introduction: The PTEN gene, also known as MMAC1 or TEP1, is a tumor suppressor gene. One of the important polymorphisms of this gene is the rs10490920 SNP. The purpose of this study was to determine the PTEN gene expression and its relation to changes in rs10490920 polymorphism in breast cancer. Methods: In this study, 40 breast cancer patients and 10 healthy controls were considered. The expr...
Aim and Background: Histones are replaced by protamines to package sperm head DNA during mammalian spermatogenesis. Protamine genes variation cause sperm DNA damage and is affect infertility in men. Therefore this study aim was investigation on association of two rs737008 in PRM1 gene and rs4780356 in PRM2 gene polymorphisms with azoospermia and oligospermia in Iranian idiopathic infertile men....
Background & Aims: 1,25-dihydroxyvitamin D3 (1,25 (OH)2 D3), the biologically active form of vitamin D, exerts an immunosuppressive effect through binding to its specific nuclear receptor. The present case-control study was done to examine the possible association of BsmI polymorphism in vitamin D receptor gene (VDR gene) with severity of multiple sclerosis (MS). Methods: 267 Iranian patients w...
Background & Aims: Lipoprotein lipase (LPL) is one of the key enzymes regulating the metabolism of triglycerides (TG) and HDL cholesterol. The lipoprotein lipase (LPL) gene polymorphisms are possibly involved in the pathophysiology of dyslipidemia. Hind III polymorphism is one of the most common polymorphisms in LPL gene. In some studies, association of Hind III polymorphism with dyslipidemia h...
the growth hormone (gh) gene is a candidate for growth trait in farm animals and plays an important role in growth metabolism. growth hormone can contribute in growth metabolism when it's receptor (ghr) are on cells target. the single nucleotide polymorphism was occurred in gh and ghr genes and that associated with carcass traits in lori-bakhtiari sheep breed with using pcr-sscp. in this r...
