Fig. 1. Overexpression of HBV DNA polymerase inhibits apoptosis of HepG2 cells. (A) Effects of overexpression of HBV Pol in HepG2 and Hela cells on the expression of eEF1A2 protein. (B) Effects of overexpression of HBV Pol in HepG2 and Hela cells on the relative expression of HBV Pol. (C) and (D) Effects of overexpression of HBV Pol in HepG2 and Hela cells on the relative expression of P- eEF1A2 and eEF1A2. (E) The cell viability of HepG2 cells under the overexpression of HBV Pol and eEF1A2. (F) Effect of HBV Pol on apoptosis of HepG2 cells with or without induction of endoplasmic reticulum (ER) stress by thapsigargin (TG). (G) Percentages of HepG2 cells undergoing apoptosis with or without ER stress inducer TG (**p < 0.01 and *p < 0.05 compared with mock-transfected cells).
