Polymorphisms of folate pathway enzymes (methylenetetrahydrofolate reductase and thymidylate synthase) and their relationship with thymidylate synthase expression in human astrocytic tumors.
Two important polymorphisms of folate cycle enzymes, methylenetetrahydrofolate reductase (MTHFR) C677T and thymidylate synthase (TS) enhancer region (TSER) 28-bp tandem repeat, are related to risk of various types of cancer, including brain tumors, although there are few studies on this subject. A case-control study of these two polymorphisms in astrocytomas of different grades was carried out ...
متن کاملFolate intake along with genetic polymorphisms in methylenetetrahydrofolate reductase and thymidylate synthase in patients with advanced gastric cancer.
BACKGROUND A relationship between dietary folate intake and efficacy of fluorouracil (FU) is supported by preclinical data. Furthermore, there are several reports that evaluated genetic polymorphisms of MTHFR (methylenetetrahydrofolate reductase) or TYMS (thymidylate synthase) and efficacy of FU. However, to our knowledge, there are no reports that evaluate simultaneously the effects of folate ...
متن کاملPrognostic significance of the polymorphisms in thymidylate synthase and methylenetetrahydrofolate reductase gene in lung cancer.
BACKGROUND Thymidylate synthase (TS) and methylenetetrahydrofolate reductase (MTHFR) play important roles in folate metabolism. Previous studies have suggested that TS expression is a prognostic factor in non-small cell lung cancer (NSCLC). The TS gene has a variable number of tandem repeats (VNTR) and single nucleotide polymorphism (SNP) in the 5'-untranslated region, which are associated with...
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...
متن کاملPolymorphisms in the reduced folate carrier, thymidylate synthase, or methionine synthase and risk of colon cancer.
Folate metabolism supports the synthesis of nucleotides as well as the transfer of methyl groups. Polymorphisms in folate-metabolizing enzymes have been shown to affect risk of colorectal neoplasia and other malignancies. Using data from a population-based incident case-control study (1,600 cases and 1,962 controls), we investigated associations between genetic variants in the reduced folate ca...
