Effect of co-treatment with Pae and tunicamycin on the expression of COX-2, phospho (p)-Akt and CHOP in HepG2 cells.

<p>Whole cell lysates from HepG2 cells with treatment with 3 µmol/L tunicamycin (TM) in either the absence (control) or the presence of 31.25 mg/LPae for 8 hr were subjected to western blotting analysis. β-actin in the same HepG2 cells extract was used as an internal used as an internal reference. Optical density reading values of the specific protein versus the loading control protein β-actin are represented as fold of the control values. (*P<0.05, **P<0.01, compared with untreated HepG2 cells, ^#P<0.05, ^##P<0.01, compared with HepG2 cells treated with tunicamycin alone).
