Regulation of 3β-Hydroxysteroid Dehydrogenase/Δ5-Δ4 Isomerase: A Review
This review focuses on the expression and regulation of 3β-hydroxysteroid dehydrogenase/Δ⁵-Δ⁴ isomerase (3β-HSD), with emphasis on the porcine version. 3β-HSD is often associated with steroidogenesis, but its function in the metabolism of both steroids and xenobiotics is more obscure. Based on currently available literature covering humans, rodents and pigs, this review provides an overview of ...
متن کاملExpression and Activity of 3β-Hydroxysteroid Dehydrogenase/Δ5-Δ4-Isomerase in the Rat Purkinje Neuron during Neonatal Life.
Recently, we demonstrated that cytochrome P450 side-chain cleavage enzyme (P450scc) occurs in the rat cerebellar Purkinje cell after differentiation and remains during neonatal development and into adulthood. 3b-Hydroxysteroid dehydrogenase/D-D-isomerase (3bHSD) is also an essential enzyme for progesterone biosynthesis not only in peripheral steroidogenic glands but also in the nervous system. ...
متن کاملIsolation of a New Mouse 3β-Hydroxysteroid Dehydrogenase Isoform, 3β-HSD VI, Expressed During Early Pregnancy.
The enzyme 3beta-hydroxysteroid dehydrogenase (3beta-HSD) is a key enzyme in the biosynthesis of steroid hormones. To date, this laboratory has isolated and characterized five distinct 3beta-HSD complementary DNAs (cDNAs) in the mouse (3beta-HSD I through V). These different forms are expressed in a tissue- and developmentally-specific manner and fall into two functionally distinct enzymes. 3be...
متن کامل3β-hydroxysteroid dehydrogenase type II deficiency on newborn screening test.
3β-hydroxysteroid dehydrogenase II (3β-HSD) deficiency represents a rare CAH variant. Newborns affected with its classic form have salt wasting in early infancy and genital ambiguity in both sexes. High levels of 17-hydroxypregnenolone (Δ517OHP) are characteristic, but extra-adrenal conversion to 17-hydroxyprogesterone (17OHP) may lead to positive results on newborn screening tests.

متن کاملEffects of genistein and equol on human and rat testicular 3β-hydroxysteroid dehydrogenase and 17β-hydroxysteroid dehydrogenase 3 activities
The objective of the present study was to investigate the effects of genistein and equol on 3β-hydroxysteroid dehydrogenase (3β-HSD) and 17β-hydroxysteroid dehydrogenase 3 (17β-HSD3) in human and rat testis microsomes. These enzymes (3β-HSD and 17β-HSD3), along with two others (cytochrome P450 side-chain cleavage enzyme and cytochrome P450 17α-hydroxylase/17-20 lyase), catalyze the reactions th...
