Interestingly, research has shown that even in animals lacking beta-3 adrenergic receptors, acute AOD-9604 administration still increased energy expenditure and fat oxidation, suggesting additional metabolic pathways may be involved beyond the primary beta-3 receptor mechanism
In research models, this mechanism has been studied in the context of photoprotection in UV-sensitive conditions particularly erythropoietic protoporphyria (EPP), where clinical development of afamelanotide as a subcutaneous implant has resulted in regulatory approval in Europe and the United States
MITF drives transcription of melanogenic enzymes including tyrosinase, TRP-1, and TRP-2, promoting eumelanin (brown/black pigment) synthesis
This review will use the term MASLD, defined as the presence of hepatic steatosis with no other discernible cause, in conjunction with at least one cardiometabolic risk factor (CMRF), such as type 2 diabetes mellitus (T2DM), obesity, hypertension, or dyslipidemia
