Abstract |
BACKGROUND/AIM:The topoisomerase 1 catalytic inhibitor 3EZ, 20Ac-ingenol specifically induces apoptosis through the activation of ATR and the up-regulation of PTEN by enhancing the DNA damage response (DDR) in human B lymphoma (BALL-1) cells. The accumulation of cyclin D1 in cancer is known to be related to chemoresistance to DNA damage agents and nuclei of BALL-1 cells exhibit high levels of cyclin D1. However, 3EZ, 20Ac-ingenol effectively induced apoptosis of BALL-1 cells. MATERIALS AND METHODS:Cell growth, protein levels, and apoptosis were determined by an MTT assay, immunoblotting and DNA fragmentation assay, respectively. RESULTS:3EZ, 20Ac-ingenol strongly induced inhibition of cell proliferation and apoptosis in Jeko-1 and Panc-1 cell lines through the activation of tumor suppressor proteins and caspase 3. CONCLUSION:3EZ, 20Ac-ingenol-induced apoptosis might occur in cells with cyclin D1 accumulation through enhancing DDR, regardless of the cancer cell type. |
