PPARG and Cachexia: The last refers to the process where, in response to stimuli, including a prolonged exposure to cold, the effects of β3-adrenergic receptor (ADRB3) agonists (here: catecholamines), peroxisome proliferator-activated receptor gamma (PPARγ, here: fibrates and thiazolidinediones), physical exercise, and cachexia, beige adipocytes appear among the WAT cells.
