Expression of MF, HFCD + DEN, and HFD32. a Principal component analysis of MF (brawn), HFCD + DEN (red), and HFD32 + DEN (blue). MF group contained three mice. HFCD + DEN and HFD32 + DEN group contained five mice. b Heat map of HCC-related genes common to both HFCD + DEN and HFD32 + DEN. DEN, diethylnitrosamine; standard diet (MF); HFCD, high-fat, choline-deficient diet; HFD32, high-fat diet
