Effect of caffeic acid cinnamyl ester (CACE) on the expressions of ER stress proteins and PPARs in palmitic acid (PA)-stimulated L02 cells. Note. (1) (a), (c) western blot analysis of IREIα, CHOP, and ATF6α protein-associated ER stress pathways, and PPARα, PPARδ, and PPARγ proteins; (b), (d) the relative expressions of IREIα, CHOP, ATF6α, PPARα, PPARδ, and PPARγ proteins. 2. 0.375% bull serum albumin (BSA) treatment is the control group; 300 μmol/L PA treatment is the model group; 300 μmol/L PA and 100 μmol/L tauroursodesoxycholic acid (TUDCA) treatment is the positive control group. Two different concentrations of CACE treatment are drug treatment groups. All values represent the mean of triplicate determinations ± SD. Significant differences () from the control group are marked with ∗ and significant differences () from the model group are marked with #.
