5. Folate and Cancer: Is There Any Association?
Abstract Folate plays a central role in DNA synthesis and methylation, which are essential for DNA integrity maintenance and gene expression. Folate deficiency may lead to the incorporation of uracil into DNA and chromosome breaks, increasing the risk of cancer. However, conflicting evidence has been observed depending on the type of epidemiological study, d

6. Isolated and Combined Remethylation Disorders: Biochemical and Genetic Diagnosis and Pathophysiology
Abstract Genetic defects affecting the remethylation pathway cause hyperhomocysteinemia. Isolated remethylation defects are caused by mutations of the 5, 10-methylenetetrahydrofolate reductase (MTHFR), methionine synthase reductase(MTRR), methionine synthase(MTR), and MMADHC genes, and combined remethylation defects are the result of mutations in genes invol

7. Micronutrients: Speculation on Inborn Errors, Nutrigenomics, Evolution, the Microbiome, and Nutritional Immunity
Abstract Many micronutrients or cofactors derived from micronutrients are highly reactive, hence their role in catalysis of reactions by enzymes. The concentration of cofactors has to be kept low to avoid unwanted reactions while allowing them to bind to the (apo)enzymes that need them. A new disorder causing B6-responsive epilepsy (proline synthetase cotran

9. Evaluation of nutritional status in children with amblyopia
RESUMO Objetivo: Nosso objetivo foi comparar o índice de massa corporal e o nível de vitaminas e minerais de crianças com e sem ambliopia. Métodos: Crianças amblióticas com idades entre 5 e 18 anos (n=46) e crianças controle pareadas por idade (n=32) foram avaliadas quanto a parâmetros antropométricos, incluindo altura, peso, índice de massa corp

10. Genetic Variants in Folate and Cobalamin Metabolism-Related Genes in Nonsyndromic Cleft Lip and/or Palate
Resumo O objetivo desse estudo foi avaliar a associação entre os polimorfismos no gene TCN2 (rs1801198) e no gene MTRR (rs1801394) com fissura de lábio e/ou palato não sindrômica (NSFL/P) em uma população brasileira. DNA genômico foi extraído de células bucais. Os polimorfismos nos genes TCN2 (rs1801198) e MTRR (rs1801394) foram genotipados atravé

11. The 19-bp deletion polymorphism of dihydrofolate reductase (DHFR) and nonsyndromic cleft lip with or without cleft palate: evidence for a protective role
Objective Nonsyndromic cleft lip with or without cleft palate (NS-CL/P) are among the most common congenital birth defects worldwide. Several lines of evidence point to the involvement of folate, as well as folate metabolizing enzymes in risk reduction of orofacial clefts. Dihydrofolate reductase (DHFR) enzyme participates in the metabolic cycle of folate a

12. Association study of folate-related enzymes (MTHFR, MTR, MTRR) genetic variants with non-obstructive male infertility in a Polish population
Spermatogenesis is a process where an important contribution of genes involved in folate-mediated one-carbon metabolism is observed. The aim of the present study was to investigate the association between male infertility and the MTHFR (677C > T; 1298A > C), MTR (2756A > G) and MTRR (66A > G) polymorphisms in a Polish population. No significant differences i
