Dietary choline reverses some, but not all, effects of folate deficiency on neurogenesis and apoptosis in fetal mouse brain.

ABSTRACT: In mice, maternal dietary folate, a cofactor in 1-carbon metabolism, modulates neurogenesis and apoptosis in the fetal brain. Similarly, maternal dietary choline, an important methyl-donor, also influences these processes. Choline and folate are metabolically interrelated, and we determined whether choline supplementation could reverse the effects of folate deficiency on brain development. Timed-pregnant mice were fed control (CT), folate-deficient (FD), or folate-deficient, choline-supplemented (FDCS) AIN-76 diets from d 11 to 17 (E11-17) of pregnancy, and on E17, fetal brains were collected for analysis. Compared with the CT group, the FD group had fewer neural progenitor cells undergoing mitosis in the ventricular zones of the developing mouse brain septum (47%; P < 0.01), hippocampus (
