ERK/AKT signaling pathway is involved in the activation of the TNF/caspase-3 cascade within ovarian cancer cells. (A) Inhibition of ERKIR decreased caspase-3 expression levels within CAOV-3 cells compared with in the control group. (B) Inhibition of ERKIR inhibited TNF-induced CAOV-3 cell apoptosis compared with in the control group. (C) PL-PTX-induced CAOV-3 cell apoptosis was inhibited via an ERK inhibitor compared with in the control group. **P<0.01. AKT, protein kinase B; ERK, extracellular signal-regulated kinase; ERKIR, ERK/AKT activity; PL-PTX, pegylated liposomal-paclitaxel; TNF, tumor necrosis factor.
