Immunoreactive corticotropin-releasing hormone (IR-CRH) in maternal plasma increases progressively during pregnancy and decreases rapidly after delivery, suggesting that IR-CRH is produced in the placenta. We studied the expression of the CRH gene in developing human chorionic tissue, the amniotic membrane, the uterine myometrium and a fresh surgical specimen of hydatidiform mole by Northern blot analysis. Our results were as follows: (1) CRH mRNA was demonstrated in the placenta in the third trimester and at term, but under detectable level in the first and second trimesters. (2) CRH mRNA expression was observed in the amniotic membrane, but its expression in the myometrium in normal pregnancy was under detectable level at term. (3) CRH mRNA was also under detectable level in trophoblasts of a hydatidiform mole. These results suggest that the sources of the increased level of IR-CRH in human plasma and amniotic fluid during pregnancy are the placenta and amniotic membrane, and that gene expression of placental CRH increases during pregnancy.
