- Background: Normal fetal development requires adequate folate levels during pregnancy. Although folate metabolic enzymes have important roles in the maintenance of normal fetal development, the location of folate metabolic enzymes, methionine synthase (MTR) and 5,10-methylenetetrahydrofolate reductase (MTHFR), has not been previously examined. Methods: We investigated the expression of MTR and MTHFR in human term placenta obtained from normal and pregnancy-induced hypertension (PIH) patients. Results: MTR is expressed in the villous syncytiotrophoblast and MTHFR is expressed in the extravillous trophoblast. There was no difference in the quantity and location of these enzymes between control and PIH patients. Conclusion: These results suggest that MTR in the villous trophoblast participates in the metabolism of homocysteine by using folate, and MTHFR in the extravillous trophoblast is associated with extratrophoblast invasion. © 2014 S.
