MAPK3 and hepatocellular carcinoma: Kaplan-Meier analysis demonstrated that increased PEG3 expression was positively correlated with poor survival in HCC patients with high activation of p-Erk1/2Thr202/Tyr204 and p-mTORSer2448 (Log-rank test, p = 0.0072; Figure 5G), whereas no significant association was found in HCC patients with low activation of p-Erk1/2Thr202/Tyr204 and p-mTORSer2448 (Log-rank test, p = 0.3427, Figure 5H).
