Abstract The aim of this paper is to study the changes of apoptosis and cell cycle progression in HeLa cells after the poly (ADP-ribose) polymerase (PARP) was inhibited by its inhibitor 3-aminobenzamide (3-AB) and the mechanisms of PARP action on HeLa cells damaged by irradiation. Flow cytometry (FCM) was used to examine the PARP expression and the percentage of apoptotic cells and cell cycle progression. The percentage of HeLa cells with positive expression of PARP protein 2, 4, 8 and 12 h after administrated with 3-AB was significantly lower than that of the control (P < 0.01). The percentages of apoptotic cells in the 3-AB plus irradiation group at the time points of 2, 8, 12 and 24 h after 2 Gy irradiation were higher than that in the irradiation group (P < 0.01 or P < 0.05) and the percentage of G2 cells decreased significantly (P < 0.01 or P < 0.05). It indicates that 3-AB can rapidly inhibit PARP expression of HeLa cells, promote cell apoptosis and block G2 arrest induced by irradiation.
