In liver, melatonin (Mel) and glucocorticoids (GC) influence the systemic energy homeostasis. Animals without pineal gland present impairment in glycemic control, as in type-2 diabetes. In turn, Mel reduces the GC levels, particularly in nocturnal animals. We aimed to evaluate the influence of Mel, as well as GC receptor blockade by RU486 treatment on hepatic and pancreatic energy metabolism. Male Wistar rats were subjected to surgical removal of pineal and, 25 days after the ...
