Targeting mitochondria and programmed cell death as potential interventions for metastatic castration-resistant...

Prostate cancer is one of the major causes of morbidity and mortality in men worldwide. Most patients with prostate cancer will turn into end-of-life stage when those tumor cells become metastatic castration-resistant prostate cancer (mCRPC). The mCRPC subsequently developed a resistance to androgen signaling. The current regimens for mCRPC therapy are still ineffective. Much evidence from in vitro and in vivo studies explored the roles of therapeutic interventions targeted at the mitochondria and programmed cell death for prostate cancer therapy. The present review will focus on the recent medications which targeted at mitochondria and programmed cell death in mCRPC and the significant findings from each study will be summarized and discussed. Development of therapeutic interventions, particularly at mitochondrial and cytotoxic targets for treatment of mCRPC without inducing cellular toxicity of normal tissues will be considered as the novel therapeutic strategy for mCRPC.
