Elucidating a comprehensive mechanism through which most patients with advanced prostate cancer have an initial response to androgen deprivation therapy, but eventually progress to a castration-resistant state is critical to establish a novel treatment strategy for castration refractory prostate cancer (CRPC). We investigate the mechanism of CRPC from the perspective of some cross-talks in signal transduction pathway between NF-kB and an intranuclear steroid receptor superfamily containing androgen receptor, glucocorticoid receptor, and estrogen receptor. Also we target the cross-talk with various methods of inhibiting the signaling transduction pathway and established the integrated treatment strategy of CRPC. Consequently, our study made it clear that cross-talk between NF-kB and an intranuclear steroid receptor superfamily might existence, and also suggested inhibiting the cross-talk of signaling pathway network might be novel therapeutics for the management of CRPC.
