Consistently, Hong at al showed that the ERK-β3-AR axis is a key player in obesity-driven increases in lipolysis and that administration of MEK inhibitors is efficient in blunting both in vivo lipolysis in diet-induced obese mice and ex vivo lipolysis induced by β3-AR agonist treatment on human and murine WAT explants [119]. Here, ADRB3 is linked to Obesity.
