Reduced MTHFD1 activity in male mice perturbs folate- and choline-dependent one-carbon metabolism as well as transsulfuration.

Impaired utilization of folate is caused by insufficient dietary intake and/or genetic variation and has been shown to prompt changes in related pathways, including choline and methionine metabolism. These pathways have been shown to be sensitive to variation within the Mthfd1 gene, which codes for a folate-metabolizing enzyme responsible for generating 1-carbon (1-C)-substituted folate derivat...

Enhancing effect of Tiliacora triandra leaves extract on spatial learning, memory and learning flexibility as well as hippocampal choline acetyltransferase activity in mice

Objective: The present study investigates the effect of Tiliacora triandra leaf extract on spatial learning, memory, and learning flexibility as well as hippocampal choline acetyltransferase (ChAT) activity in mice.  Materials and Methods: Thirty male ICR mice were randomly divided into three groups including 10% Tween 80, T. triandra 300 mg/kg and T. triandra 600 mg/kg. All administrations wer...

Maternal Mthfd1 disruption impairs fetal growth but does not cause neural tube defects in mice.

BACKGROUND MTHFD1 encodes C1-tetrahydrofolate synthase, which is a folate-dependent enzyme that catalyzes the formation and interconversion of folate-activated one-carbon groups for nucleotide biosynthesis and cellular methylation. A polymorphism in MTHFD1 (1958G→A) impairs enzymatic activity and is associated with increased risk of adverse pregnancy outcomes, but the mechanisms are unknown. ...

Autism and Folate-dependent One-carbon Metabolism: Serendipity and Critical Branch-point Decisions in Science

Folate-dependent one-carbon metabolism is present in every cell of the body. It represents a central systems biology hub that reverberates into countless other pathways with more specialized roles in specialized cell types throughout the body. I have spent 25 years of research on this core biochemical pathway with several unanticipated iterations that led me from Down syndrome to congenital hea...

Ontogeny of hepatic enzymes involved in serine- and folate-dependent one-carbon metabolism in rabbits.

Serine occupies a central position in folate-dependent, one-carbon metabolism through 5,10-methylenetetrahydrofolate (MTHF) and 5-formyltetrahydrofolate (FTHF). We characterized the ontogeny of the specific activity of key enzymes involved in serine, 5,10-MTHF, and 5-FTHF metabolism: methenyltetrahydrofolate synthetase (MTHFS), MTHF reductase (MTHFR), the glycine cleavage system (GCS), methioni...
