BACKGROUND The association between methylenetetrahydrofolate reductase (MTHFR) gene polymorphisms and hepatocellular carcinoma (HCC) risk was inconsistent and underpowered. To clarify the effects of MTHFR gene polymorphisms on the risk of HCC, a meta-analysis of all available studies relating C677T and/or A1298C polymorphisms of MTHFR gene to the risk of HCC was conducted. METHODS The authors...
زمینه: یکی از فاکتورهای مطرح در ایجاد ترومبوفیلی در زنان مبتلابه سقط مکرر، پلی مورفیسم های a1298c و c677t در ژن mthfr است. هدف از این تحقیق بررسی ارتباط این دو پلی مورفیسم باسندرم سقط مکرر به عنوان یکی از ریسک فاکتورهای ژنتیکی برای این سندرم بود.روش کار: 30 زن با سابقه سقط مکرر خودبه خودی باعلت نامشخص به عنوان گروه بیماران و 10 زن بدون سابقه سقط مکرر و دارای حداقل دو باروری موفق، به عنوان گروه ...
PURPOSE Methylenetetrahydrofolate reductase (MTHFR) directs intracellular folate toward homocysteine metabolism and away from nucleotide synthesis. Two common MTHFR polymorphisms, C677T and A1298C, are associated with reduced enzyme activity. We evaluated the association of these polymorphisms with risk of relapse and bcr-abl mRNA transcript detection among 336 Caucasian patients who underwent ...
AIMS This study aimed to investigate the association between the methylene tetrahydrofolate reductase (MTHFR) gene C677T and A1298C polymorphisms and premature delivery susceptibility. METHODS With matched age and gender, 108 premature delivery pregnant women as cases and 108 healthy pregnant women as controls were recruited in this case-control study. The cases and controls had same gestatio...
BACKGROUND Several epidemiological studies have investigated the associations of methylenetetrahydrofolate reductase (MTHFR) C677T and A1298C polymorphisms with hypertension (H) or hypertension in pregnancy (HIP). However, the results were controversial. We therefore performed a comprehensive meta-analysis to provide empirical evidences on the associations. METHODOLOGIES The English and Chine...
Folate is key in one-carbon metabolism, disruption of which can interfere with DNA synthesis, repair, and methylation. Efficient one-carbon metabolism requires other B vitamins and the optimal activity of enzymes including 5,10-methylenetetrahydrofolate reductase (MTHFR). We report a population-based case-control study of folate intake, related dietary factors and MTHFR polymorphisms (C677T, A1...
INTRODUCTION Cleft lips and cleft palates are common congenital abnormalities in children. Various chromosomal loci have been suggested to be responsible the development of these abnormalities. The present study was carried out to investigate the association between the suspected genes (methylenetetrahydrofolate reductase [MTHFR] A1298C and C677T) that might contribute into the etiology of thes...
Type 2 diabetic nephropathy is a major cause of end-stage renal disease. MTHFR plays a vital role in folate metabolism, DNA methylation, and RNA synthesis. The aim of this study was to investigate the association between MTHFR C677T and A1298C genomic polymorphisms and development of type 2 diabetic nephropathy in a Chinese population. A hospital-based case-control study was performed. A total ...
Introduction Migraine is a painful complex neurovascular disease characterized by recurrent moderate-to-severe headaches. Increased level of homocysteine is related to dilation of cerebral vessels and endothelial injury that could trigger migraine attacks. Functional polymorphisms in the MTHFR gene affect homocysteine metabolism and, therefore, play an important role in the etiology of the dise...
Methylenetetrahydrofolate reductase (MTHFR) C677T and A1298C polymorphisms are, independently and/or in combination, associated with many disorders. However, data on the combined genotype and haplotype distributions of the 2 polymorphisms in Chinese population were limited.We recruited 13,473 adult women from 9 Chinese provinces, collected buccal cell samples, and determined genotypes, to estim...
