Anticancer drugs increased the death of cells latently infected with HIV-1. a Cells were treated with etoposide (5 μM) and doxycycline (0.5 μM) for 36 h. The sub-G1 population (dead cells) of cells was determined by flow cytometry after PI staining (left panel). The data are shown graphically with statistical analysis (right panel). The data are shown as mean ± SD (n = 3). *p <0.05, **p <0.01 compared with A3.01 cells. b Western blotting was used to determine the levels of expression of p53 and p-p53 using appropriate antibodies under same conditions
