Dhea Action Is Mediated By Multiple Receptors And Metabolites., Kristy K. Michael Miller

Electronic Theses and Dissertations

Dehydroepiandrosterone (DHEA) is a C-19 adrenal steroid and the most abundant circulating hormone in humans. Since circulating levels decline in late adulthood, treatment of humans with DHEA has been suggested to have beneficial health effects. Although the mechanism of action is unknown, DHEA may be metabolized to active metabolites that exert their physiological effects by receptor-mediated processes and cell signaling pathways. The purpose of this study was to investigate the mechanistic processes of DHEA action. Since DHEA may exert its pleotropic effects by being metabolized to biologically active species, a GC/MS method was developed to quantify the liver microsomal metabolism …
