Effect on protein expression of UPR targets. a Relative protein expression of BIP and (b) ratio of protein expression of p-elF2α and total elf2α in the liver of rats fed diets with either soybean oil or salmon oil with various vitamin E concentrations. Bars represent relative protein level expressed as fold of control (diet with soybean oil and 25 mg/kg vitamin E) and are means ± SD from 12 animals per group. Representative immunoblots specific to BIP (a), p-elF2α and total elf2α (b) and ß-actin and α-tubulin as respective loading controls are shown for one animal per group
