Effects of vitamin D on primary human trophoblast amino acid transport were studied. 1,25-dihydroxy vitamin D3 increased mRNA expression of the System A isoform SNAT2. 1,25-dihydroxy vitamin D3 stimulated system A amino acid transport activity. Trophoblast mTOR signaling was not regulated by1,25-dihydroxy vitamin D3. Altered placental amino acid transport may link maternal vitamin D to fetal growth.
