title: Protective effect of Bojungbangdocktang on cisplatin-induced cytotoxicity and apoptosis in MCF-10A breast endothelial cells.
abstract: Although cisplatin has been extensively used as a cancer chemotherapeutic agent for the treatment of various human cancers, it causes significant side effects such as nephrotoxicity and hepatotoxicity due to lethal bystander damage to normal cells. Thus, in the current study, we investigated the Oriental herbal medicine Bojungbangdocktang (BJBDT), as we reported previously its anti-angiogenic activity at nontoxic concentrations that could prevent cisplatin-induced toxicity and apoptosis in human normal breast epithelial cell MCF-10A, but not in MCF-7 and MDA MB-231 breast cancer cells. BJBDT protected cisplatin-induced cytotoxicity in MCF-10A cells and potentiated cytotoxicity and MMP loss in MCF-7 cells. Also, 4',6-diamidino-2-phenylindole (DAPI) staining and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) assay revealed that BJBDT reduced cisplatin-induced apoptotic bodies in MCF-10A cells compared with cisplatin-treated control. Consistently, BJBDT attenuated the apoptotic portion sub-G1 DNA contents as well as blocked the activation of caspase-3 and -9 and poly(ADP-ribose)polymerase (PARP) cleavage in cisplatin-treated MCF-10A cells. Taken together, our findings suggest that BJBDT can protect cisplatin-induced cytotoxicity and apoptosis in normal MCF-10A breast cells as a cancer chemopreventive agent.
