A prospective study of methylenetetrahydrofolate reductase and methionine synthase gene polymorphisms, and risk of colorectal adenoma.
We examined the relationship between a functional polymorphism (667C-->T, ala-->val) of the methylenetetrahydrofolate reductase gene (MTHFR) and the risk of colorectal adenomas in the prospective Nurses' Health Study. Among 257 incident polyp cases and 713 controls, the MTHFR val/val polymorphism [relative risk (RR) = 1.35, 95% confidence interval (CI) 0.84-2.17] was not significantly associate...
متن کاملAssociation of methylenetetrahydrofolate reductase gene polymorphisms & colorectal cancer in India.
BACKGROUND & OBJECTIVES Methylenetetrahydrofolate reductase (MTHFR) is a critical enzyme in folate metabolism and involved in DNA synthesis, DNA repair and DNA methylation. The two common functional polymorphisms of MTHFR, 677 C-->T and 1298 A-->C have shown to impact several diseases including cancer. This case-control study was undertaken to analyse the association of the MTHFR gene polymorph...
متن کاملThe Polymorphisms in Methylenetetrahydrofolate Reductase, Methionine Synthase, Methionine Synthase Reductase, and the Risk of Colorectal Cancer
Polymorphisms in genes involved in folate metabolism may modulate the risk of colorectal cancer (CRC), but data from published studies are conflicting. The current meta-analysis was performed to address a more accurate estimation. A total of 41 (17,552 cases and 26,238 controls), 24(8,263 cases and 12,033 controls), 12(3,758 cases and 5,646 controls), and 13 (5,511 cases and 7,265 controls) stu...
متن کاملPrevalence of genetic polymorphisms of methylenetetrahydrofolate reductase C677T and angiotensin I-converting enzyme (insertion/deletion) in Sétif population, Algeria
The aim of the present study was to assess the frequencies of angiotensin I-converting enzyme (ACE; OMIM: 106180) and methylenetetrahydrofolate reductase (MTHFR; OMIM: 607093) polymorphisms in the Algerian population to further facilitate investigations on possible associations with various pathologies. The study was carried out on 146 apparently healthy individuals (65 males, 81 females) who w...
متن کاملThymidylate synthase and methylenetetrahydrofolate reductase gene polymorphisms and toxicity to capecitabine in advanced colorectal cancer patients.
PURPOSE To evaluate the effect of thymidylate synthase (TYMS) and methylenetetrahydrofolate reductase (MTHFR) genotypes on toxicity in patients treated with capecitabine for advanced colorectal cancer and to determine the effect of these polymorphisms on the pretreatment levels of serum folate and plasma homocysteine. EXPERIMENTAL DESIGN Fifty-four patients with a diagnosis of metastatic colo...
