ULK1 and metabolic dysfunction-associated steatohepatitis: To test the hypotheses that hepatic expression of ULK1, one of the most upstream autophagy-related factors, and autophagy induction are suppressed in NASH, and that restoration of ULK1 expression and induction of autophagy can be achieved by treatment with gemigliptin in MCD diet–induced NASH mice, ULK1 and autophagy induction were evaluated in the model.
