We found that folate receptor alpha (FRalpha) and reduced folate carrier (RFC) localized on the apical side of human placental villi. Since folate binding to placental brush-border membrane vesicles (BBMVs) was strongly inhibited by phosphatidylinositol-specific phospholipase C (PI-PLC) treatment, it is possible that FRalpha, a glycosyl phosphatidylinositol linked glycoprotein, is a candidate for folate uptake from maternal blood to the placenta. Moreover, additional inhibitory effects of thiamine pyrophosphate (TPP) and hemin on folate uptake after PI-PLC treatment suggested that not only FRalpha but also RFC and heme carrier protein 1 (HCP1) are involved in the folate transport mechanism in the human placenta. It was also found that accumulation of folate after intravenous injection increased with the progress of gestation in the rat placenta and the fetus. Furthermore, increases in the expression levels of mRNA of rFRalpha, rRFC, and rHCP1 in the rat placenta during pregnancy were observed. These findings suggest that FRalpha, RFC, and HCP1 are important carriers of folate in the placenta during pregnancy. The results of this study suggest that increases in the expression levels of FRalpha, RFC, and HCP1 in the placenta play an important role in the response to increased need for folate for the placenta and fetus during development with the progress of gestation."xsd:string |
