BACKGROUND Ischemic stroke is a major health problem. Data regarding the possible association between ischemic stroke and the polymorphism of methylenetetrahydropholate reductase (MTHFR) C677T and A1298C are still conflictual. AIM The study tried to assess the association of the two MTHFR polymorphisms with ischemic stroke in a series of patients from a unique hospital center. MATERIALS AND...
Background and purpose: Coronary artery disease (CAD) is a complex disease that is caused by both environmental and genetic factors. Methylenetetrahydrofolate (MTHFR) enzyme is associated with metabolism of homocysteine and its impaired function is considered as a risk factor for developing CAD. Some variants are involved in decreased activity of MTHFR and its deficiency. The polymorphism of C6...
We analyzed the role of the C677T polymorphism of the 5,10-methylenetetrahydrofolate and the A66G polymorphism of the methionine synthase reductase genes as risk factors for occurrence of spina bifida. The studied population included 106 mothers and 104 children from affected families, and a control group of 100 adults. We found statistically significant differences between the occurrence of th...
سرطان سینه یک بیماری هتروژن است که در اثر رشد بی رویه سلول ها در سلول های بافت سینه آغاز می شود و از علل اصلی مرگ و میر در میان زنان جهان می باشد. در سال های اخیر سرطان سینه یکی از سرطان های رایج در کشور های در حال توسعه و یا کم درآمد بوده است و یک بیماری با فاکتورهای چند عاملی می باشد که با عوامل محیطی و عوامل ژنتیکی در ارتباط است. ژن mthfr در انتهای بازوی کوتاه کروموزوم 1 قرار گرفته است که نق...
سابقه و هدف: سرطان دهانه رحم یکی از سرطانهای شایع در زنان میباشد. فاکتورهای متعددی در ابتلا به این سرطان نقش دارند که میتوان به عفونت پاپیلوما ویروس (HPV)، تغییرات اپیژنتیکی از جمله متیلاسیون غیرطبیعی پروموتر ژن متیلن تتراهیدروفولات ردوکتاز (MTHFR) و برخی پلیمورفیسمها از جمله، پلیمورفیسم MTHFR C677T اشاره کرد. MTHFR آنزیمی است که در تنظیم متابولیسم فولات و متیونین نقش دارد. هدف از این ت...
There are several evidences supporting the role of 5-10 methylenetetrahydrofolate reductase (MTHFR) gene polymorphisms in breast cancer (BC). Case control association studies on breast cancer have been repeatedly performed over the last two decades, but results are inconsistent. We performed a meta-analysis to confirm the association between MTHFR C677T polymorphism and BC risk. The articles we...
BACKGROUND The MTHFR C677T single nucleotide polymorphism TT genotype is associated with increased levels of plasma homocysteine and possibly an effect on cardiovascular mortality. We evaluated the effect of C677T genotype on mortality in a large end-stage renal disease (ESRD) cohort. METHODS C677T genotype was determined in 439 Caucasians with end-stage diabetic nephropathy (DNP) (cases) rec...
The role of methylenetetrahydrofolate reductase (MTHFR) C677T, A1298C, methioninesynthase reductase (MTRR) A66G was unclear in repeated spontaneous abortion. To provide experimental basis for etiological diagnosis and treatment of recurrent spontaneous abortion, we selected 197 patients with recurrent spontaneous abortion and 116 normal women, extracting the oral mucosal epithelial cells and de...
