Short description:
In the current study, we show that brown adipose tissue (BAT) activity is dramatically reduced in a dehydroepiandrosterone (DHEA)-induced polycystic ovary syndrome (PCOS) rat when compared with a normal control rat. Importantly, the key features of PCOS (such as insulin resistance and irregular estrous cycle) are alleviated after BAT transplantation. Mechanistically, transplanted BAT enhances endogenous BAT activity and thereby increases the circulating adiponectin level, which was lower in both the PCOS patient and PCOS rat model. Furthermore, exogenous adiponectin protein administration recapitulates beneficial effects from BAT transplantation in a PCOS rat. Taken together, these data highlight the important role of BAT in the development of PCOS and that BAT-induced adiponectin might open up a new way in the treatment of PCOS.

Abstract:
Polycystic ovary syndrome (PCOS), which is characterized by anovulation, hyperandrogenism, and polycystic ovaries, is a complex endocrinopathy. Because the cause of PCOS at the molecular level is largely unknown, there is no cure or specific treatment for PCOS. Here, we show that transplantation of brown adipose tissue (BAT) reversed anovulation, hyperandrogenism, and polycystic ovaries in a dehydroepiandrosterone (DHEA)-induced PCOS rat. BAT transplantation into a PCOS rat significantly stabilized menstrual irregularity and improved systemic insulin sensitivity up to a normal level, which was not shown in a sham-operated or muscle-transplanted PCOS rat. Moreover, BAT transplantation, not sham operation or muscle transplantation, surprisingly improved fertility in PCOS rats. Interestingly, BAT transplantation activated endogenous BAT and thereby increased the circulating level of adiponectin, which plays a prominent role in whole-body energy metabolism and ovarian physiology. Consistent with BAT transplantation, administration of adiponectin protein dramatically rescued DHEA-induced PCOS phenotypes. These results highlight that endogenous BAT activity is closely related to the development of PCOS phenotypes and that BAT activation might be a promising therapeutic option for the treatment of PCOS.
