Effect of BEPP on PKR, eIF2α, AKT, cyclin D1, and MAPK activity.
MEF/PKR(+/+) and MEF/PKR(-/-) cells were treated with the indicated
concentrations of BEPP for 72 h. Whole-cell lysates were analyzed for total
and active (phosphorylated) PKR, eIF2α, and cyclin D1, total and active
(phosphorylated) AKT, active p38, and JNK by Western blotting. β-Actin
was used as a loading control.
