ZDHHC3 and metabolic dysfunction-associated steatohepatitis: Hepatocyte‐specific dysfunction of ZDHHC3 significantly inhibits palmitoylated IRHOM2 deposition, therefore suppressing the fatty‐acids‐mediated hepatosteatosis and inflammation in vitro, as well as NASH pathological phenotype induced by two different high‐energy diets (HFHC & WTDF) in the in vivo rodent and rabbit model.
