Targeting the androgen receptor axis provides only temporary relief for advanced prostate cancer, which often evolves into androgen‑independent disease. The wide variety of signaling mechanisms connected with the pathophysiology of androgen‑independent prostate cancer poses both conceptual and practical challenges for the design of efficient therapies. Analysis of apoptosis regulation in prostate cancer suggests the potential value of a systems approach that integrates information on the topology of the antiapoptotic signaling network, the signal transduction pathways that inhibit apoptosis, and the expression of proteins of the Bcl2 family. This approach could be used to identify patients most likely to respond to treatments with drugs that inhibit the signaling pathways controlling apoptosis.
