Hydroxysteroid (17β) Dehydrogenase 7 Activity Is Essential for Fetal de Novo Cholesterol Synthesis and for Neuroectodermal Survival and Cardiovascular Differentiation in Early Mouse Embryos

Abstract excerpt

Hydroxysteroid (17beta) dehydrogenase 7 (HSD17B7) has been shown to catalyze the conversion of both estrone to estradiol (17-ketosteroid reductase activity) and zymosterone to zymosterol (3-ketosteroid reductase activity involved in cholesterol biosynthesis) in vitro. To define the metabolic role of the enzyme in vivo, we generated knockout mice deficient in the enzyme activity (HSD17B7KO). The data showed that...
