Abstract:
Yes-associated protein 1 (YAP1) plays a pivotal role in promoting the progression of hepatocellular carcinoma (HCC). Emerging evidence shows that inducing YAP1 degradation represents a promising strategy. Here, we identified USP24 as a bona fide deubiquitinating enzyme for YAP1. USP24 directly interacts with and deubiquitinates YAP1, thereby stabilizing YAP1 protein levels. Clinically, USP24 was significantly upregulated in HCC tissues and correlated with poor patient prognosis. Depletion of USP24 significantly suppressed the proliferation of HCC cells in vitro, which could be rescued by restoration of YAP1. Consistent with these findings, USP24 knockdown inhibited tumor growth in a xenograft mouse model. Overall, our study reveals that the USP24/YAP1 axis plays a critical role in the malignant progression of HCC, thus providing rationale for potential therapeutic interventions for YAP1-driven HCC.
