Methylene tetrahydrofolate reductase (MTHFR) and vascular endothelial growth factor (VEGF) polymorphisms in Brazilian patients with Hepatitis C virus (HCV)-related hepatocellular carcinoma (HCC)

Clinics; 76 (), 2021
OBJECTIVE: The folate pathway is involved in hepatic carcinogenesis and angiogenesis. Polymorphisms in genes related to such processes, including methylene tetrahydrofolate reductase (MTHFR) and vascular endothelial growth factor (VEGF)] may play an important role in the development of hepatocellular car...

Trombosis senovenosa cerebral en un recién nacido con mutación MTHFR C677T tratado con enoxaparina

Rev. chil. pediatr; 91 (3), 2020
Resumen: Introducción: La trombosis senovenosa cerebral neonatal (TSVC), es una patología rara y generalmente grave, de la cual se conoce poco sobre los mecanismos fisiopatológicos responsables y, aunque controvertido, se ha sugerido que la trombofilia genética, puede desempeñar un rol en la patog...

miR-9-1 gene methylation and DNMT3B (rs2424913) polymorphism may contribute to periodontitis

J. appl. oral sci; 28 (), 2020
Abstract Genetic and epigenetic changes have been associated with periodontitis in various genes; however, little is known about genes involved in epigenetic mechanisms and in oxidative stress. Objective: This study aims to investigate the association of polymorphisms C677T in MTHFR (rs1801133) and W...

L-methylfolate, a new option in psychiatric treatment, would it be linked to psoriasis relapse?

ABSTRACT We report a case of a 61-years-old woman in remission of psoriasis for 20 years. She presented recurrence of psoriasis in the form of plaques few days after taking L-methylfolate 15mg/day. The L-methylfolate was prescribed as an adjuvant for the treatment of depression in a patient with the meth...

Methylenetetrahydrofolate Reductase deficiency and anesthesia: importance of a detailed preoperative evaluation

Rev. bras. anestesiol; 69 (6), 2019

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...

The relationship between of ACE I/D and the MTHFR C677T polymorphisms in the pathophysiology of type 2 diabetes mellitus in a population of Brazilian obese patients

ABSTRACT Objectives This study aimed to evaluate the frequencies of the angiotensin converting enzyme (ACE) gene insertion/deletion (I/D) and methylenetetrahydrofolate reductase (MTHFR) gene C677T polymorphisms in obese patients with and without type 2 diabetes mellitus (T2DM). Subjects and methods The...

Prevalence of the MTHFR C677T Mutation in Fertile and Infertile Women

Abstract Introduction The importance of the C677T mutation in the methylenetetrahydrofolate reductase (MTHFR) gene in infertile women remains controversial. Objective To evaluate if the MTHFR C677T mutations are more frequent in infertile women, and if they can be associated with the occurrence of in...

Global and gene-specific DNA methylation and hydroxymethylation in human skin exposed and not exposed to sun radiation

An. bras. dermatol; 92 (6), 2017
Abstract: Background: epigenomes can be influenced by environmental factors leading to the development of diseases. Objective: To investigate the influence of sun exposure on global DNA methylation and hydroxymethylation status and at specific sites of the miR-9-1, miR-9-3 and MTHFR genes in skin sampl...

Methylene tetrahydrofolate reductase, transforming growth factor-β1 and lymphotoxin-α genes polymorphisms and susceptibility to rheumatoid arthritis

Rev. bras. reumatol; 56 (5), 2016
ABSTRACT Background: Rheumatoid arthritis is a widely prevalent autoimmune disorder with suggested genetic predisposition. Objectives: The aim of this study is to detect the pattern of genetic polymorphism of methylene tetrahydrofolate reductase (MTHFR C677 T and A1298 C), transforming growth factor-&#...
