1,25-Dihydroxy vitamin D3 stimulates system A amino acid transport in primary human trophoblast cells
In conclusion, 1,25-dihydroxy vitamin D3 regulates System A activity through increased mRNA expression of SNAT2 transporters. Effects on placental amino acid transport may be the mechanism underlying the association between maternal vitamin D status and fetal growth.

Maternal 25 ‐hydroxyvitamin D is inversely correlated with fetal serotonin
ConclusionsThese observations provide the first evidence of an inverse relationship between maternal 25(OH)D and fetal serotonin concentrations. We propose that maternal vitamin D deficiency increases fetal serotonin concentrations and thereby contributes to longer‐term neurocognitive impairment in infants and children.This article is protected by copyright.

Altered folate metabolism modifies cell proliferation and progesterone secretion in human placental choriocarcinoma JEG-3 cells.
Abstract Folate is an essential B vitamin required for de novo purine and thymidylate synthesis, and for the remethylation of homocysteine to form methionine. Folate deficiency has been associated with placenta-related pregnancy complications, as have SNP in genes of the folate-dependent enzymes, methionine synthase (MTR) and methylenetetrahydrofolate dehydrogenase 1 (MTHFD1). We aimed to determine the effect of altered folate metabolism on placental cell proliferation, viability and invasive capacity and on progesterone and human chorionic gonadotropin (hCG) secretion. Human placental choriocarcinoma (JEG-3) cell...
