Folic acid and methylenetetrahydrofolate reductase (MTHFR) may both affect the development of human cancer. We conducted a population-based case-control study in a Chinese population to investigate the potential role of folate intake and MTHFR gene polymorphisms in gastric cancer, and their interaction with infection by Helicobacter pylori and tumor location. A total of 767 patients with newly ...
BACKGROUND Methylenetetrahydrofolate reductase (MTHFR) plays a central role in converting folate to methyl donor for DNA methylation. Because MTHFR is a key enzyme in folate metabolism, changes in its activity resulting from polymorphisms in the MTHFR gene could modify the susceptibility to cancer. Recently, the C677T and A1298C mutations of MTHFR were discovered to be associated with susceptib...
Hyperhomocysteinemia is an independent risk factor for ischemic stroke. The enzyme methylenetetrahydrofolate reductase (MTHFR) plays a critical role in modulating the levels of plasma homocysteine. Two polymorphisms in the MTHFR gene, C677T, A1298C result in reduced enzyme activity. The mechanisms of ischemic and hemorrhagic stroke are not well understood. Although controversial, previous studi...
سابقه و هدف: سرطان دهانه رحم یکی از سرطان های شایع در زنان می باشد. فاکتورهای متعددی در ابتلا به این سرطان نقش دارند که می توان به عفونت پاپیلوما ویروس (hpv)، تغییرات اپی ژنتیکی از جمله متیلاسیون غیرطبیعی پروموتر ژن متیلن تتراهیدروفولات ردوکتاز (mthfr) و برخی پلی مورفیسم ها از جمله، پلی مورفیسم mthfr c677t اشاره کرد. mthfr آنزیمی است که در تنظیم متابولیسم فولات و متیونین نقش دارد. هدف از این تح...
PURPOSE Behcet's disease (BD) is a multisystemic immunoinflammatory disorder characterized by mucocutaneous, ocular, vascular, and central nervous system manifestations. The common methylene tetrahydrofolate reductase (MTHFR) gene C677T mutation is a known risk factor for thrombosis. The aim of this study was to investigate the MTHFR gene C677 mutation in patients with BD and evaluate if there ...
BACKGROUND/AIMS Hyperhomocyst(e)inaemia has been identified as a strong risk factor for stroke, myocardial infarction, and deep vein thrombosis. A point mutation of methylene tetrahydrofolate reductase (MTHFR C677T) has been associated with increased plasma homocyst(e)ine levels. To investigate whether hyperhomocyst(e)inaemia and/or MTHFR C677T mutation are associated with non-arteritic ischaem...
Numerous studies have evaluated the association between MTHFR C677T polymorphism and osteoporotic fracture risk in postmenopausal women. However, the results have been inconsistent. We performed a meta-analysis of the association between MTHFR C677T polymorphism and osteoporotic fracture risk in postmenopausal women. Only seven case-control studies were retrieved, with a total of 4258 patients ...
Genetic polymorphisms (C677T and A1298C) in methylenetetrahydrofolate reductase (MTHFR) were shown to be related to prostate cancer risk in previous studies; however, the results are controversial. We performed a meta-analysis of previous studies and quantitatively estimated these associations. Pubmed, Embase, and Cochrane Library Database were searched for published case-control studies evalua...
The authors performed a meta-analysis of studies examining the association between polymorphisms in the 5,10methylenetetrahydrofolate reductase (MTHFR) gene, including MTHFR C677T and A1298C, and common psychiatric disorders, including unipolar depression, anxiety disorders, bipolar disorder, and schizophrenia. The primary comparison was between homozygote variants and the wild type for MTHFR C...
It has been demonstrated that inflammatory bowel disease (IBD) patients had a higher risk of thromboembolism, numerous observational studies have reported the prevalence of MTHFR C677T mutation and G20210A prothrombin mutation in patients with IBD. Whereas the magnitude of association between these two inherited thrombophilic abnormalities and IBD remains unknown. We conduct a meta-analysis to ...
