The purpose of this study was to examine the association between the methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism and bone mineral density (BMD). Two large cohort studies were performed: the Dong-gu Study (3,621 men and 5,409 women) and the Namwon Study (3,703 men and 5,672 women). We assessed lumbar spine and femoral neck BMD by dual-energy X-ray absorptiometry. Genotypes wer...

BACKGROUND There are conflicting results on the relationship of N5,N10-methylenetetrahydrofolate reductase C677T gene variation in coronary artery disease and myocardial infarction. METHODS AND RESULTS We analysed this gene variation in 2453 male Caucasians whose coronary anatomy was defined by coronary angiography. In the total sample, the C677T gene polymorphism was not associated with the ...

UNLABELLED The aim of this study was to evaluate the association and interaction of genotypic polymorphisms in methylenetetrahydrofolate reductase (MTHFR) and environmental factors with lung cancer in Taiwan. Two well-known polymorphic variants of MTHFR, C677T (rs1801133) and A1298C (rs1801131), were analyzed in association with lung cancer susceptibility, and discussed their joint effects with...

Here we report design, synthesis and characterization of highly sensitive, specific and stable in biological systems fluorescent probes for point mutation detection in DNA. The tandems of 3'- and 5'-mono- and bis-pyrene conjugated oligo(2'-O-methylribonucleotides), protected by 3'-"inverted" thymidine, were constructed and their potential as new instruments for genetic diagnostics was studied. ...

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...

We constructed an assay to detect the common C677T mutation in the methylenetetrahydrofolate reductase gene. The mutation creates a Hinfl recognition site detected by restriction cleavage of a 198-bp fragment amplified in the polymerase chain reaction (PCR). Digested samples were subjected to capillary electrophoresis with laser-induced fluorescence detection (CE-LIF), with hydroxypropylmethylc...

Fifteen patients with cerebral venous thrombosis were ascertained retrospectively. Their case notes were reviewed, and stored or new blood was assayed for factor V Leiden (FVL) mutation, prothrombin gene mutation 20201A, and 5,10 methylene tetrahydrofolate reductase (MTHFR) C677T mutation. A clinical risk factor was identified in 13 patients--the oral contraceptive pill (5), puerperium (1), HRT...

Sickle cell disease (SCD) is one of the most common inherited diseases in the world and the patients present notorious clinical heterogeneity. It is known that patients with SCD present activation of the blood coagulation and fibrinolytic systems, especially during vaso-occlusive crises, but also during the steady state of the disease. We determined if the presence of the factor V gene G1691A m...

BACKGROUND Although single nucleotide polymorphisms may be potentially important pharmacogenetic determinants of cancer therapy, functional evidence regarding their relevance is currently lacking. The C677T polymorphism in the methylenetetrahydrofolate reductase (MTHFR) gene is associated with changes in cellular composition of folates. We hypothesized that this polymorphism may modulate the cy...

Prostate cancer is the most common cause of cancer death in men and is a major health problem worldwide. Methylene tetrahydrofolate reductase (MTHFR) plays an important role in folate metabolism and is also an important source of DNA methylation and DNA synthesis (nucleotide synthesis). To assess the association and interaction of genotypic polymorphisms in MTHFR and lifestyle factors with pros...
