CPT1A suppression induces lipid accumulation and inhibits cell viability. a Immunoblotting analysis of ATGL and DGAT1 in 5-8F and CNE2 cells treated with etomoxir at the indicated concentration for 24 h. b and c Immunoblotting analysis of CPT1A, ATGL and DGAT1 expression in 5-8F and CNE2 cells transfected with CPT1A or vector. d Lipid droplet in 5-8F and CNE2 cells were visualized by Oil red O staining and were counterstained with hematoxylin. Scale bar: 50 μm. e Detection of intracellular triglyceride content by a triglyceride kit. f CCK-8 assays of 5-8F and CNE2 cells treated with etomoxir at the indicated concentration for 24 h. g and h CCK-8 assays with 5-8F and CNE2 cells treated with etomoxir (400 μM) at the indicated time points. All error bars represent the S.D. of three replicates from two independent experiments. * p < 0.05,**p < 0.01 compared with the control
