Epigenetic regulation of folate receptor-α (FOLR1) in human placenta of preterm newborns.

abstract：:Gestational diabetes mellitus is a common medical complication in pregnancy. Recent findings demonstrate that glyburide is effluxed against a concentration gradient from the fetal to the maternal circulation. However, the transport systems involved in the active efflux of glyburide in the human placenta have not yet b...
