PARP Inhibition Suppresses GR–MYCN–CDK5–RB1–E2F1 Signaling and Neuroendocrine Differentiation in Castration-Resistant Prostate Cancer

Abstract

The results of our study indicate an important role of GR-MYCN-CDK5R1/2-RB1-NED signaling in ENZ-induced and PARP inhibitor-suppressed NEPC. We also demonstrated efficacy for OLA+DINA combination therapy in NEPC xenograft models.
