- Aim: Glucocorticoids (GCs) play a crucial role in energy homeostasis including white adipose tissue function; however, chronic GC excess is detrimental to mammals' health. White hypertrophic adiposity is a main factor for neuroendocrine-metabolic dysfunctions in monosodium L-glutamate (MSG)-damaged hypercorticosteronemic rat. Nevertheless, little is known about the receptor path in endogenous GC impact on white adipose tissueresident precursor cells to bring them into beige lineage. Thus, our aim was to explore whether transient/ chronic endogenous hypercorticosteronemia affects browning capacity in white adipose tissue pads from MSG rats during development. Main methods: Control and MSG male rats aged 30 and 90 days were 7-day exposed to cold conditions in order to stimulate wet white epidydimal adipose tissue (wEAT) beiging capacity. This procedure was also replicated in adrenalectomized rats. Key findings: Data indicated that whereas epidydimal white adipose tissue pads from prepubertal hypercorticosteronemic rats retained full expression of GR/MR genes resulting in a drastic reduction in wEAT beiging capacity, conversely, chronic hypercorticosteronemic adult MSG rats developed down-regulation of corticoid genes (and reduced GR cytosolic mediators) in wEAT pads and consequently partially restored local beiging capacity. Finally, wEAT pads from adrenalectomized rats revealed up-regulation of GR gene accompanied by full local beiging capacity. Significance: This study strongly supports a GR-dependent inhibitory effect of GC excess on white adipose tissue browning, an issue strongly supporting a key role of GR in the non-shivering thermogenic process. As a consequence, normalizing the GC milieu could be a relevant factor to handle dysmetabolism in white hyperadipose phenotypes.
