Brief summary: This basic science study in mice shows how melanocortin neurons integrate reproductive signaling with energy homeostasis. In melanocortin neurons, estradiol (E2) enhances the anorectic action of leptin. Cited1 is enriched in these neurons and its loss exacerbates diet-induced obesity in female mice. Using several specific mouse models it is demonstrated how hypothalamic Cited1, via ERα and Stat3 interactions, link the effects of E2 and leptin on food intake...

Nature Metabolism. 2020;2(2):192–209. doi: 10.1038/s42255-020-0171-3.This experimental mouse study examined whether or not dedifferentiated β cells could be reversed or targeted by pharmacological intervention for diabetes remission. They identified evidence for β-cell dedifferentiation and dysfunction which could be reversed by single and combined pharmacological approach...
