The prostate cancer (PCa) poses serious threat to men's health. The androgen receptor (AR) is essential for normal prostate development and prostate cancer progression. We identified a novel lncRNA PCLN16 which is significantly correlated with AR signaling during prostate cancer progression. The AR-regulated PCLN16 was abundantly overexpressed in localized or metastatic prostate cancer tissues and AR-dependent cell lines. PCLN16 silence suppressed AR signaling and tumor growth. PCLN16 interacted with Huntingtin interacting protein 1 (HIP1) transcript to reduce HIP1 degradation. Therefore, PCLN16 could augment AR signaling via a novel positive feedback loop. Our experiments support an oncogenic role for PCLN16 and suggest that PCLN16 might serve as a potential target for therapeutic intervention. Copyright © 2020 Elsevier Inc. All rights reserved.
