[ 2 ] - The POLG Gene Polymorphism in Iranian Varicocele-Associated Infertility Patients
Objective(s) Varicocele is associated with impaired testicular function and male infertility, but the molecular mechanisms by which fertility is affected have not been satisfactorily explained. The aim of our study was to investigate whether or not the polymerase gamma (POLG) polymorphism is associated with Iranian varicocele patients. Materials and Methods We determined the POLG CAG repe...
[ 3 ] - Novel Missense Mitochondrial ND4L Gene Mutations in Friedreich's Ataxia
Objective(s) The mitochondrial defects in Friedreich's ataxia have been reported in many researches. Mitochondrial DNA is one of the candidates for defects in mitochondrion, and complex I is the first and one of the largest catalytic complexes of oxidative phosphorylation (OXPHOS) system. Materials and Methods We searched the mitochondrial ND4L gene for mutations by TTGE and sequencing on 30...
[ 4 ] - تغییرات نوکلئوتیدی ژن‌های CoxII، سیتوکروم b و tRNAGlu میتوکندریایی در بیماران ایرانی مبتلا به سندرم بروگادا (آریتمی قلبی)
Introduction: The Brugada syndrome (BrS) belongs to cardiac arrhythmia disorders that is seen on the echocardiogram bands and is a significant cause of sudden death in young adults. At the molecular level, mechanisms that contribute to BrS are mutations in genes that encode for ion channels. It has been reported that the activity of ion channels in cardiomyocytes is sensitive to ATP level. This...
[ 5 ] - های اسید گلوتامیک، تریپتوفان، آلانین tRNA بررسی مولکولی در Long QT وآسپارژین درژنوم میتوکندری بیماران مبتلا بهسندرم مقایسه با گروه کنترل
Background and purpose: Long QT syndrome is a heart arrhythmia identified by prolongation of the QT interval which is a cause of sudden cardiac death in young individuals. In most cases, abnormalities in heart repolarization are reasons of prolongation of action potential and arrhythmia. The activity of ion channels is sensitive to ATP level, therefore, mitochondrial disorders are considered...
[ 6 ] - بررسی جهش در اگزون 8 ژن CLCN1 در بیماران ایرانی مبتلا به میوتونی غیر دیستروفیک
Background: Non-dystrophy myotonias (NDMs) have similar clinical signs of muscle weakness and congenital myotoniais typical example. This disease is caused by mutations in CLCN1 gene. CLCN1 gene has 23 exons and exon 8 is hotspot. Mutations in skeletal muscle chloride channel gene are associated with a group of clinically overlapping diseases by alterations in the excitability of the sarcolemma...
[ 7 ] - Molecular Analysis of rs2070744 and rs1799983 Polymorphisms of NOS3 Gene in Iranian Patients With Multiple Sclerosis
Introduction: Multiple Sclerosis (MS) is a disease of central nervous system that mainly causes lesions or plaques in the spinal cord and brain. The purpose of this study was to analyze the relation between c.-813C>T (rs2070744) and c.894G>T (rs1799983) polymorphisms of NOS3 gene and MS in Iranian patients. Methods: A total of 78 patients with MS and 80 healthy controls were screened for NOS3 ...
[ 8 ] - Designing and Validation of One-Step T-ARMS-PCR for Genotyping the eNOS rs1799983 SNP
Background: The transversion of G to T (G894T) in human endothelial nitric oxide synthase (eNOS) gene has profound effects such as male infertility, recurrent miscarriage, multiple sclerosis and cardiovascular diseases.Objectives: Development of a new Multiplex Tetra-Primer Amplifi cation Refractory Mutation System - Polymerase Chain Reaction (T-ARMS-PCR) for detection of...
[ 9 ] - Protective effect of Berberis vulgaris on Fenton reaction-induced DNA cleavage
Objective: Berberis vulgaris contains antioxidants that can inhibit DNA cleavage. The purpose of this study was to evaluate the antioxidant and protective activity of B. vulgaris on DNA cleavage. <span style="font-size: medium;"...
[ 10 ] - The Study of Nitric Oxide Synthase 3 (NOS3) T-786C and 4a4b Gene Polymorphism in Iranian Men with Varicocele
Background and Objectives: Varicocele is one of the most common causes of male infertility. Varicocele is an abnormal dilatation and tortuosity of veins of the pampiniform plexus, which drain the testis. Studies have shown that elevated level of oxidative stress markers, such as nitric oxide (NO) in the dilated veins of patients with varicocele impair testicular function. The aim of this study,...
[ 11 ] - Molecular Mechanisms of Recurrent Pregnancy Loss
Introduction: Pregnancy and health is the process in which the egg is fertilized and being able to survive. When pregnancy occurs under some conditions and the fetus is being at risk, it will lead to abortion that occurs involuntarily and spontaneously. Abortions that occur more than two or three times are called recurrent pregnancy loss (RPL). Various etiological factors involved in RPL, inclu...
[ 12 ] - Association of Pathogenic Missense and Nonsense Mutations in Mitochondrial COII Gene with Familial Adenomatous Polyposis (FAP)
Nuclear genetic mutations have been extensively investigated in solid tumors. However, the role of the mitochondrial genome remains uncertain. Since the metabolism of solid tumors is associated with aerobic glycolysis and high lactate production, tumors may have mitochondrial dysfunctions. Familial adenomatous polyposis (FAP) is a rare form of colorectal cancer and an autosomal dominant inheri...
[ 13 ] - In-silico study to identify the pathogenic single nucleotide polymorphisms in the coding region of CDKN2A gene
Background: CDKN2A, encoding two important tumor suppressor proteins p16 and p14, is a tumor suppressor gene. Mutations in this gene and subsequently the defect in p16 and p14 proteins lead to the downregulation of RB1/p53 and cancer malignancy. To identify the structural and functional effects of mutations, various powerful bioinformatics tools are available. The aim of this study is the ident...
[ 14 ] - Analysis of Missense Mutations of CX3CR1 Gene in Patients with Recurrent Pregnancy Loss Using Bioinformatics Tools
Introduction: Abortion is a common complication that refers to the early termination of pregnancy with the death of the fetus before the 20th week of pregnancy. Previous studies show that many genes are involved in this disease, including the CX3CR1 gene, which is one of the inflammatory response genes in the immune system. The pathogenicity of these variants was determined in this study using ...
[ 15 ] - Genetic Analysis of D-Loop Region of Mitochondrial DNA Sequence in Iranian Patients with Familial Adenomatous Polyposis (FAP): A Case-Control Study
Background and Objectives: Familial adenomatous polyposis (FAP) is an inherited disorder and a rare form of colorectal cancer. This disease appears equally in both sexes and its occurrence is more in the second or third decade of life. Mutations and alterations of the mitochondrial genome, especially the D-loop region, have been reported in various human tumors. But the exact role of these muta...
