Hydroxysteroid 17-beta dehydrogenase 1 (HSD17B1) is an enzyme catalyzing the reduction of estrone (E1) to estradiol (E2), as well as androstenedione (Adione) to testosterone (T). To elucidate the physiological function of HSD17B1, we generated knockout mice with disrupted Hsd17b1 gene using targeted ES cells (clone 10231) obtained from KOMP repository (www.komp.org). In these ES cells the whole coding region of Hsd17b1 was replaced with LacZ/Neo cass...

Hydroxysteroid (17-β) dehydrogenase enzymes (HSD17Bs) have an important role in sex steroid hormone metabolism. They are known to catalyze reactions between highly active 17β-hydroxy steroids and less active 17-keto steroids. In addition to sex steroid metabolism, it is becoming evident that HSD17Bs have functions in other pathways as well, e.g. lipid and bile acid metabolism. HSD17B type 7 enzyme is known to catalyze in vitro the activation of estrone (E1) to...
