摘要

The autophagy of human prostate cancer cells (PC3 cells) induced by a new anthraquinone derivative, 1-Hydroxy-3-[(E)-4-(piperazine-diium)but-2-enyloxy]-9,10-anthraquinone ditrifluoroactate (PA) was investigated, and the relationship between autophagy and reactive oxygen species (ROS) generation was studied. The results indicated that PA induced PC3 cell death in a time- and dose-dependent manner, could inhibit PC3 cell growth by G1 phase cell cycle arrest and corresponding decrease in the G2/M cell population and induced S-phase arrest accompanied by a significant decrease G2/M and G1 phase numbers after PC3 cells treated with PA for 48 h, and increased the accumulation of autophagolysosomes and microtubule-associated protein LC3-ll, a marker of autophagy. However, these phenomenon were not observed in the group pretreated with the autophagy inhibitor 3-MA or Bafilomycin A1 (BAF), suggesting that PA induced PC3 cell autophagy. In addition, we found that PA triggered ROS generation in cells, while the levels of ROS decreased in the N-acetylcysteine (NAC) co-treatment, indicating that PA-mediated autophagy was partly blocked by NAC. In summary, the autophagic cell death of human PC3 cells mediated by PA-triggered ROS generation.
