TRIM33 is an oncogenic transcriptional coactivator stabilizing AR from Skp2-mediated ubiquitin-proteasomal degradation in prostate cancer [RNA-Seq]

Project description:Using a proteomics approach, we identified the Tripartite Motif Containing 33 (TRIM33) as a novel transcriptional coactivator of AR. We demonstrate TRIM33 facilitates the AR chromatin binding to directly regulate a transcription program that promotes PCa progression by protecting AR from Skp2-mediated ubiquitination and proteasomal degradation. We also show TRIM33 is essential for PCa tumor growth by avoiding cell cycle arrest and apoptosis, and TRIM33 knockdown sensitizes PCa cells to AR antagonists. In clinical analyses, we find TRIM33 is upregulated in multiple PCa patient cohorts. Finally, we uncover an AR-TRIM33 coactivated gene signature that is highly expressed in PCa tumors and predicts disease recurrence. Overall, our results reveal TRIM33 is an oncogenic AR coactivator in PCa and a potential therapeutic target for PCa treatment.
