1. Association of methylenetetrahydrofolate reductase ( MTHFR ) gene polymorphisms (C677T and A1298C) with thyroid dysfunction: A meta-analysis and trial sequential analysis
ABSTRACT Recent studies have shown that two common methylenetetrahydrofolate reductase ( MTHFR ) gene polymorphisms (C677T and A1298C) might correlate with thyroid dysfunction, but the results remain inconsistent. We carried out a meta-analysis aiming to assess the relationship of both polymorphisms with thyroid dysfunction. The PubMed, EMBASE, CNKI (China N

3. Impact of CPS1 Gene rs7422339 Polymorphism in Argentine Patients With Hyperhomocysteinemia
Abstract Carbamoyl phosphate synthetase 1 (CPS1) is a key gene in the first step of urea cycle and has been correlated with nitric oxide level and vascular smooth muscle activity. A functional single-nucleotide polymorphism C/A at position 4217 in CPS1 (National Center for Biotechnology Information SNP database no. rs7422339, T1405N) was reported to be assoc

4. MTHFR gene polymorphisms in hypothyroidism and hyperthyroidism among Jordanian females
ABSTRACT Objective Methylenetetrahydrofolate reductase (MTHFR) is involved in DNA methylation that is associated with autoimmune pathology. We investigated the association between MTHFR genetic polymorphisms at g.677C>T and g.1298A>C and their haplotypes, and the risk of thyroid dysfunction among Jordanian females. Subjects and methods A case-control stu

5. Methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism in psoriasis in southern Turkey
Abstract: Background: Psoriasis is a multigenic and multifactorial dermatological disease linked to cardiovascular diseases. Increased levels of homocysteine in patients with psoriasis have been demonstrated in many studies. The most frequently investigated genetic defect that plays a role in homocysteine metabolism is single point substitution (C to T) loc

6. The MTHFR C677T polymorphism and global DNA methylation in oral epithelial cells
DNA methylation is mediated by DNA methyltransferases (DNMTs) that add a methyl group to the 5'-carbon of cytosine. The enzyme methylenetetrahydrofolate reductase (MTHFR) catalyzes the reduction of 5,10-methylenetetrahydrofolate to 5-methyltetrahydrofolate in the rate-limiting step of the cycle involving the methyl donor S-adenosyl-L-methionine (SAM). The MT

7. Relação do hábito alimentar e polimorfismos da MTHFR C677T com a instabilidade genômica em fumicultores gaúchos
Genetic damage can occur spontaneously under normal metabolic circumstances and can also be present in situations of dietary deficiency or inadequate intake of nutrients and excessive exposure to environmental mutagens. The purpose of this study was to evaluate the influence of the intake of micronutrients B12, B6 and folate and of polymorphism MTHFR C677T i

8. Avaliação do polimorfismo C677T (ALA222VAL) do gene da metilenotetrahidrofolato redutose (MTHFR) da hemocisteína e-493G/T do gene da proteína microssomal transportadora de triglicerídeos (MTP) em pacientes com hepatite C crônica do Nordeste do Brasil / Methylenetetrahydrofolate reductase (MTHFR) C677T (ALA222VAL) polimorphysm and microsomal triglyceride transfer protein (MTP) -493G/T polymorphism in chronic hepatitis C patients from Northeast of Brazil
Introdução: A infecção crônica pelo vírus da hepatite C (VHC) está associada à presença da resistência insulínica e da esteatose hepática, independentemente dos fatores metabólicos do hospedeiro. A alteração na enzima MTHFR resulta em hiperhomocisteinemia, que altera o metabolismo intracelular dos lipídios e pode estar relacionada à esteatos

9. Avaliação de polimorfismos envolvidos no metabolismo do folato em pacientes com câncer de cabeça e pescoço. / Avaliação de polimorfismos envolvidos no metabolismo do folato em pacientes com câncer de cabeça e pescoço.
O carcinoma de cabeça e pescoço pode ser decorrente de alterações na metilação do DNA associadas ao metabolismo anormal do folato. Concentrações reduzidas desse nutriente podem diminuir a capacidade de reparo do DNA, resultando em alterações celulares malignas que modulam a função e expressão dos genes. Polimorfismos em genes que participam da v

10. Association of homocysteine and methylene tetrahydrofolate reductase (MTHFR C677T) gene polymorphism with coronary artery disease (CAD) in the population of North India
The implications of the methylene tetrahydrofolate reductase (MTHFR) gene and the level of homocysteine in the pathogenesis of coronary artery disease (CAD) have been extensively studied in various ethnic groups. Our aim was to discover the association of MTHFR (C677T) polymorphism and homocysteine level with CAD in north Indian subjects. The study group con

11. Genetics of homocysteine metabolism and associated disorders
Homocysteine is a sulfur-containing amino acid derived from the metabolism of methionine, an essential amino acid, and is metabolized by one of two pathways: remethylation or transsulfuration. Abnormalities of these pathways lead to hyperhomocysteinemia. Hyperhomocysteinemia is observed in approximately 5% of the general population and is associated with an

Análise de polimorfismos dos genes HFE, fator V de Leiden, protrombina, glutationa-S transferase, metilenotetrahidrofolato e o risco de doença veno-oclusiva hepática em pacientes submetidos a transplante alogênico de células tronco hematopoiéticas: Estudo clínico observacional. / Inglês: Analysis genetic polymorphisms of HFE, prothrombin, factor V Leiden, methylenetetrahydrofolate reductase, glutathione S-transferase in hepatic veno-occlusive disease after hematopoietic stem cell transplantation: a observe clinical study.
Introdução: Polimorfismos genéticos estão associados com um aumento do risco de tromboembolismo venoso (TEV) e outras doenças cardiovasculares. Estudos prévios sugerem que a doença venooclusiva hepática (DVOH), que se desenvolve intra transplante de medula óssea pode ser atribuída à polimorfismos gênicos. Objetivos: Avaliar a correlação entre p
