Reduced Placental 11β-Hydroxysteroid Dehydrogenase Type 2 mRNA Levels in Human Pregnancies Complicated by Intrauterine Growth Restriction: An Analysis of Possible Mechanisms

Abstract excerpt

11beta-Hydroxysteroid dehydrogenase type 2 (11beta-HSD2) inactivates cortisol to cortisone. In the placenta 11beta-HSD2 activity is thought to protect the fetus from the deleterious effects of maternal glucocorticoids. Patients with apparent mineralocorticoid excess owing to mutations in the 11beta-HSD2 gene invariably have reduced birth weight, and we have recently shown reduced placental 11beta-HSD2 activity in...
