Corosolic acid a natural triterpenoid induces ER stress-dependent apoptosis in human castration resistant prostate cancer cells via activation of IRE-1/JNK PERK/CHOP and TRIB3

摘要

BackgroundThe development of potent non-toxic chemotherapeutic drugs against castration resistant prostate cancer (CRPC) remains a major challenge. Corosolic acid (CA), a natural triterpenoid, has anti-cancer activity with limited side effects. However, CA anti-prostate cancer activities and mechanisms, particularly in CRPC, are not clearly understood. In this study, we investigated CA anti-tumor ability against human CRPC and its mechanism of action.
