Abstract: Colorectal cancer (CRC) is the third most common cancer and the second most deadly cancer worldwide. It is of great importance to explore new mechanisms and therapeutic targets. Ubiquitin-specific protease 4 (USP4), as a key regulator of protein stability, has been proven to be closely associated with cancer progression. In addition, it has been found that evodiamine, a novel alkaloid, can effectively inhibit the stemness of colorectal cancer. Based on this, in this study, we explored in depth the interaction mechanism between USP4 and evodiamine in regulating cancer stemness. Our research data showed that the expression level of USP4 in CRC tissues and cells was significantly increased. Further experiments found that overexpression of USP4 could significantly enhance the migration and invasion of CRC and promote the expression of stemness-related genes such as SOX9, OCT4, and CD133. In contrast, knockdown of USP4 expression in CRC cells had the opposite effect. Moreover, USP4 promotes the progression of CRC by mediating the deubiquitination and stabilization of SOX9 protein. At the same time, evodiamine can significantly inhibit the expression of USP4, SOX9, OCT4, and CD133 in CRC cells. Its mechanism of action lies in the fact that evodiamine disrupts the deubiquitination process of USP4 on SOX9 protein, thereby effectively inhibiting the stemness of CRC. Developing an Evodiamine derivative will provide new approach for improving the outcome of CRC patients.
