Real-time PCR analysis of hepatic lipogenic gene expression. Rat primary hepatocytes were incubated with or without insulin (100 nM) in the presence or absence of BSA (0.15%), OLA (100 μM), EPA (100 μM), or DHA (100 μM). After 24 hours of treatment, cells were lysed and total RNA isolated. (A.) Expression of SREBP-1c, (B.) SREBP-1c target genes, (C.) and known transactivators of SREBP-1c were assessed by real-time PCR. Values expressed as the fold change from vehicle + BSA control and are the mean of at least four hepatocyte preparations (n ≥ 4). * P ≤ 0.05 vs. vehicle + BSA, # P ≤ 0.05 vs. insulin + BSA.
