  • Exploiting Dependence of Castration-Resistant Prostate Cancer on the Arginine Vasopressin ...

    Stimulation of AVPR2 with a selective agonist desmopressin promoted CRPC cell proliferation through cAMP In contrast, blocking AVPR2 with a selective FDA-approved antagonist, tolvaptan, reduced cell growth. Combinatorial use of AVPR1A and AVPR2 antagonists promoted apoptosis synergistically in CRPC cells. Furthermore, we found that castration-resistant cells produced AVP, the endogenous ligand for arginine vasopressin receptors, and knockout of AVP in CRPC cells significantly reduced proliferation suggesting
