Some studies showed that expression of genes encoding lipid metabolism-related enzymes, for example, acetyl-CoA carboxylase (ACC), fatty acid synthetase (FAS), and carnitine palmitoyltransferase (CPT), was significantly altered in NAFLD [21], further confirming a close correlation between the occurrence of NAFLD and disorders in hepatic lipid metabolism. This evidence concerns the gene FAS and metabolic dysfunction-associated steatotic liver disease.
