Ferulic acid ameliorates NAFLD by inhibiting free fatty acid uptake via the histone deacetylase 1 (HDAC1) / peroxisome proliferator- activated receptor gamma (PPAR-γ or PPARG) axis, which may provide potential dietary sdupplements and drugs [52]. The gene discussed is HDAC1; the disease is metabolic dysfunction-associated steatotic liver disease.
