This study analyzed the four main polymorphisms of the genes in homocysteine metabolism in malaria patients. Forty-two randomly selected subjects, diagnosed positive for Plasmodium falciparum, were included. The four genotypes were detected by real-time PCR using the MTHFR 677C>T, MTHFR 1298A>C, MTR 2756A>G, and MTRR 66A>G detection kit (Sacace Biotechnologies REF: T01002-96-S). The results rev...
Objectives: Down syndrome (DS) may be associated with congenital heart defects (CHD). Folate-metabolizing genes have been suspected as risk factors in DS and in CHD. We investigated the role of methylenetetrahydrofolate reductase (MTHFR) C677T and A1298C polymorphisms and methionine synthase (MTR) A2756G polymorphism as risk factors for CHD in DS offspring. Material and Methods: This study incl...
Folate and methionine metabolism is involved in DNA synthesis and methylation processes. Polymorphisms in the genes of folate metabolism enzymes have been associated with some forms of cancer. In a case-control study, we evaluated whether four common polymorphisms in methylenetetrahydrofolate reductase (MTHFR C677T and A1298C), methionine synthase (MS A2756G), and methionine synthase reductase ...
OBJECTIVE To evaluate the role of key enzymes in the methionine-homocysteine metabolism (MHM) in the physiopathology of preeclampsia (PE). METHODS Plasma and placenta from pregnant women (32 controls and 16 PE patients) were analyzed after informed consent. Protein was quantified by western blot. RNA was obtained with RNA purification kit and was quantified by reverse transcritase followed by...
اوتیسم با اختلال در ارتباط متقابل و گفتار، رفتارهای تکراری و ارتباطات اجتماعی مشخص می شود. علت اوتیسم تا حد زیادی ناشناخته است اما عوامل ژنتیکی و محیطی ممکن است در ایجاد اوتیسم نقش داشته باشند. اخیراً نشان داده شده است که ژن های دخیل در مسیر فولات/هموسیستئین ممکن است عوامل خطر برای کودکان مبتلا به اوتیسم باشند. متیونین سنتاز (mtr)، یکی از ژن هایی است که ممکن است عامل خطر برای اوتیسم باشد. mtr بر...
The cystathionine β-synthase (CBS) 844ins68 polymorphism, methionine synthase (MS) A2756G SNP, and 5,10-methylenetetrahydrofolate reductase (MTHFR) C677T SNP are associated with homocysteine (Hcy) level in humans. Elevated Hcy level is considered a risk factor for atherosclerotic diseases among Asian populations. Therefore, the three polymorphisms may vary the risk for developing such diseases ...
We previously reported that 2 polymorphisms in the 5,10-methylenetetrahydrofolate reductase (MTHFR) gene at positions C677T and A1298C were associated with lower risk of adult acute lymphocytic leukemia (ALL). In the present study, we have examined whether polymorphisms in other folate-metabolizing genes play a role in ALL susceptibility. Polymorphisms in methionine synthase (MS A2756G), cytoso...
Folate-mediated one-carbon metabolism (FMOCM) is linked to DNA synthesis, methylation, and cell proliferation. Vitamin B6 (B6) is a cofactor, and genetic polymorphisms of related key enzymes, such as serine hydroxymethyltransferase (SHMT), methionine synthase reductase (MTRR), and methionine synthase (MS), in FMOCM may govern the bioavailability of metabolites and play important roles in the ma...
