dc.description.abstract | This study was focused on investigating the anticancer potential of indole-3-carbinol (I3C) against lung cancer H1299 cells via an increase in ROS levels. To investigate the induction of growth arrest and/or cell death in H1299 cells, a cell cycle arrest assay, terminal deoxynucleotidyl transferase (TdT)-mediated dUTP-biotin nick-end labeling (TUNEL) assay, and reactive oxygen species (ROS) detection assay were performed. Through the TUNEL assay, we detected I3C-induced DNA fragmentation. Fluorescence-activated cell sorting (FACS) analysis showed that I3C induced an increase in ROS levels and apoptotic rate in a dose- and time-dependent manner in H1299 cells. Western blotting demonstrated that activated forms of caspase-3, caspase-7, caspase-9, and poly (ADP-ribose) polymerase (PARP) were increased in I3C-treated H1299 cells following treatment with I3C. Furthermore, protein expression levels of FOXO3, bim, bax, and phosphorylated ERK and JNK were increased, while those of pAkt, Bcl-xL, and Bcl-2 were decreased by I3C treatment of H1299 cells. To confirm the relationship between cell apoptosis and ROS generation, H1299 cells were treated with I3C simultaneously with N-acetylcysteine (NAC), and it was shown that ROS levels decreased and viability increased. Moreover, in western blot analysis, expression of anti-apoptotic proteins (thioredoxin1, peroxiredoxin-1, Bcl-2, and Bcl-xL) in I3C-treated cells was evidently downregulated and pro-apoptotic proteins (active ASK1 and cleaved PARP) were upregulated compared to cells co-treated with NAC. The study showed that I3C induced downregulation of ROS regulator proteins and elevation of ROS, thus activating apoptotic signaling cascades in human lung cancer H1299 cells. © The Author(s) 2020. | - |
