Project A09 deals with the over-activation of adrenal function and glucocorticoid (GC) signaling which lead to severe metabolic complications. It is understood that Glucocorticoid hormones, acting through the GC- receptor, are the principal effectors of the hypothalamic- pituitary- adrenal (HPA) axis in systemic energy homeostasis. It uses distinct microRNA as mediators in hepatic metabolism, so the project hypothesizes that the GC- controlled microRNAs act as prognostic and diagnostic markers under conditions of HPA dysfunction. It focuses on the identification of mircoRNA layers downstream of the HPA axis, which are expressed in and secreted from adipose tissue to furthermore characterize their functional impact on systemic energy metabolism.
