Does a novel antitumor piperazine alkyl compound cause apoptosis by inducing RhoB expression via ROS‑mediated c‑Abl/p38 MAPK signaling?
The antitumor agent KR28 induces apoptosis of PC-3 cells by ROS-mediated RhoB expression via c-Abl upregulation and activation of p38 MAPK/ATF-2.
These data demonstrate a greater pro-inflammatory host response and cell signalling response to bacteria present in more anaerobic conditions, and hypersensitivity of epithelial cells to pro-inflammatory stimuli at 2% oxygen, which may have implications for disease pathogenesis and/or therapy.
