The glucocorticoid receptor in brown adipocytes is dispensable for control of energy homeostasis

ABSTRACT: Aberrant activity of the glucocorticoid (GC)/glucocorticoid receptor (GR) endocrine system has been linked to obesity-related metabolic dysfunction. Traditionally, the GC/GR axis has been believed to play a crucial role in adipose tissue formation and function in both, white (WAT) and brown adipose tissue (BAT). While recent studies have challenged this notion for WAT, the contribution of GC/GR signaling to BAT-dependent energy homeostasis remained unknown. Here, we have generated and characterized a BAT-specific GR knockout mouse (GRBATKO), for the first time allowing to genetically interrogate the metabolic impact of BAT GR. The HPA axis in GRBATKO mice was intact, as was the ability of mice to adapt to cold. BAT GR was dispensable for the adaptation to fasting-feeding cycles and the d
