Protein expression of CPT-1a (A), DGAT2 (B), CD36 (C) and FATP2 (D) proteins in AML12 cells exposed to 0.3 M palmitic acid (PA) with or without resveratrol (R) or its metabolites (R-4G, R-3G, R-S and DH-R) at 1µM. The western blot bands shown are representative of 6 samples/group. CPT-1a, DGAT2, CD36 and FATP2 protein expressions were normalized by α-tubulin. Data are means ± SEM. * p < 0.05, and ** p < 0.01 vs. the control cells. # p < 0.05 vs. PA group. CPT-1a: carnitine palmitoyl-transferase 1a; DGAT2: diacylglycerol O-acyltransferase 2; CD36: fatty acid-transporter, and FATP2: very long-chain acyl-CoA synthetase 1.
