Abstract

The prevalence of nonalcoholic steatohepatitis (NASH) caused by estrogen deficiency increased sharply in recent decades and has become a major threat to liver health in postmenopausal women. There is no effective strategy to control the incidence and development of NASH. Dehydroepiandrosterone (DHEA) is the most abundant circulating steroid with immune and metabolic regulatory properties, and its level markedly declines with increasing age in humans. Importantly, DHEA can convert into active sex hormones depending on the local needs of target tissues with little diffusion, which serves to avoid systemic side-effects from other tissues' exposure to estrogen. Here, we found that DHEA prevented the incidence and development of NASH, which is characterized by the reduction of hepatic steatosis, fibrosis, and inflammation in female mice fed with high-fat/high-cholesterol diets and effectively attenuated lipid accumulation, inflammatory response, and oxidative stress in palmitic acid-challenged hepatocytes. Mechanistically, in vitro and in vivo studies showed that the anti-NASH function of DHEA depended on its biotransformation into estrogen rather than androgen, and which up-regulates the expression of G protein-coupled estrogen receptor (GPR30), a non-classical estrogen receptor. The activation of GPR30-mediated AMP-activated protein kinase signaling is a necessary prerequisite for the alleviative effects of DHEA on NASH. Collectively, our data show the mechanisms of DHEA treatment and its effects on NASH that were previously overlooked; the data also show that GPR30 can be used as a target for treating lipid metabolism disorders and related diseases, such as NASH. Furthermore, these findings have the potential to help researchers develop new strategies for preventing NASH in postmenopausal women.
