FASN and metabolic dysfunction-associated steatohepatitis: Atorvastatin intervention in NASH animals significantly attenuated only the expression of Scd1. Atorvastatin did not modulate the expression of the majority of molecules in chow diet–fed animals but did increase the expression of uptake and lipogenic genes, CD36, FA synthase (Fasn), and acetyl-CoA carboxylase (Acc).
