Application

5α-Androstan-17β-ol-3-one, also referred to as androstanolone or dihydrotestosterone, is an anabolic steroid. Testosterone secreted by the testis is converted to dihydrotestosterone in the target tissues where it appears to mediate many of the biological actions of testosterone, including the development of the male phenotype during embryogenesis and at puberty.

Biochem/physiol Actions

Androstanolone is an anabolic steroid. Testosterone secreted by the testis is converted to dihydrotestosterone in the target tissues where it appears to mediate many of the biological actions of testosterone. Androgens direct the development of the male phenotype during embryogenesis and at puberty.

Sex steroids are involved in sex determination in almost all vertebrates, including species with temperature-dependent sex determination (TSD). It is well established that aromatase and estrogens are involved in ovary determination in TSD species. In contrast, the role of non-aromatizable

Autonomic sympathetic nerves innervate peripheral resistance arteries, thereby regulating vascular tone and controlling blood supply to organs. Despite the fundamental importance of blood flow control, how sympathetic arterial innervation develops remains largely unknown. Here, we identified the axon guidance cue
