Fig. 2: Autophagy inhibition potentiates doxorubicin sensitivity for HCC cells.

a LC3 and p62 protein expression in control HCC cells and HCC cells treated for 48 h with chloroquine (20 μM), doxorubicin (0.25 μg/ml), or doxorubicin plus chloroquine. b Relative cell viability for HepG2, HuH-7, SNU-387, and SNU-449 cells treated with doxorubicin in the presence or absence of chloroquine for 48 h
