Nitric oxide modulates folate-mediated one-carbon metabolism and mitochondrial energy levels of peaches during cold storage

Frontiers in Nutrition, 2023
Folate-mediated one-carbon metabolism (FOCM) is closely associated with postharvest preservation. This study investigated the effects of exogenous nitric oxide (NO) on FOCM, storage quality, energy metabolism, and mitochondrial membrane integrity in cold-

Polymorphisms in Methionine Synthase, Methionine Synthase Reductase and Serine Hydroxymethyltransferase, Folate and Alcohol Intake, and Colon Cancer Risk [PDF]

Lifestyle Genomics, 2008
<i>Background/Aims:</i> We examined associations among folate and alcohol intake, single nucleotide polymorphisms (SNPs) in genes involved in one-carbon metabolism, and colon cancer risk. <i>Methods:</i> Colon cancer cases (294 African-Americans and 349 whites) were frequency matched to population controls (437 African-Americans

Interactions between vitamin B2, the MTRR rs1801394 and MTR rs1805087 genetic polymorphisms, and colorectal cancer risk in a Korean population [PDF]

Epidemiology and Health
OBJECTIVES We explored whether the association between vitamin B2 and colorectal cancer (CRC) risk could be modified by the MTRR rs1801394 and MTR rs1805087 genetic polymorphisms and examined whether the interaction effects are sex-specific.

Association of homocysteine and polymorphism of methylenetetrahydrofolate reductase with early-onset post stroke depression

Frontiers in Nutrition, 2022
BackgroundHomocysteine (Hcy) has been indicated to be involved in pathophysiology of post stroke depression (PSD). There is a lack of research to study the relationship between Hcy metabolism genes and PSD.

Lack of association between genetic polymorphisms in enzymes associated with folate metabolism and unexplained reduced sperm counts. [PDF]

PLoS ONE, 2009
BACKGROUND: The metabolic pathway of folate is thought to influence DNA stability either by inducing single/double stranded breaks or by producing low levels of S-adenosyl-methionine leading to abnormal gene expression and chromosome segregation ...

Sex-specific dysregulation of cysteine oxidation and the methionine and folate cycles in female cystathionine gamma-lyase null mice: a serendipitous model of the methylfolate trap

Biology Open, 2015
In addition to its role in the endogenous synthesis of cysteine, cystathionine gamma-lyase (CGL) is a major physiological source of the vasorelaxant hydrogen sulfide.

Association of methionine synthase rs1801394 and methionine synthase reductase rs1805087 polymorphisms with meningioma in adults: A meta-analysis

Biomedical Reports, 2014
Several epidemiological studies suggested that methionine synthase (MTRR) rs1801394 and methionine synthase reductase (MTR) rs1805087 polymorphisms may be involved in the risk of meningioma in adults; however, the results from different case-control studies have been inconsistent.

Polymorphism of Folate Metabolism Genes among Ethnic Kazakh Women with Preeclampsia in Kazakhstan: A Descriptive Study

Biology
Introduction: Preeclampsia is a severe multifactorial complication of pregnancy. Studies found associations between folate metabolism genes’ polymorphisms and preeclampsia. However, investigations in this field are limited among Asian populations.
