AB CCK8 assay showed that combined avasimibe and etomoxir enhanced the efficacy in the HepG2 and HUH7 (means ± SEM, n = 3). Chou and Talalay analyzed the combination indices (CI) of combined AVA and ETO for 48 h in HepG2 and HUH7. The straight line at CI = 1 represents the additive effects of both drugs. Fraction effect (FA): growth inhibition rate. C Representative images of the EdU staining assay in HUH7 cells treated with AVA, ETO, or both. D The colony formation assay of HepG2 and HUH7 cells cultured with 2 μM AVA and/or 25 μM ETO for 14 days. E Western blot analysis of CDK4, CDK6, and Cyclin D1 in HepG2 and HUH7 cells treated with 20 μM AVA and/or 150 μM ETO. F Western blot analysis of CyclinD1, CPT1A, and SOAT1 after transfection with si-SOAT1and/or si-CPT1A in PLC/PCF/5 and HUH7. GI Levels of total acetyl-CoA, ATP and β-hydroxybutyrate in HCC cells treated with AVA (5 μM) and/or ETO (50 μM) (mean ± SEM, n = 3); *p < 0.05, **p < 0.01, ***p < 0.001; ns: no significance. J Levels of intrahepatic FFAs in HepG2 and HUH7 treated with AVA (5 μM) and/or ETO (50 μM) (mean ± SEM, n = 3); *p < 0.05.
