Abstract

Abstract Colon cancer (CRC) is a common type of cancer and has a high incidence worldwide. Protein 74 (WDR74), which consists of the WD repetition sequence, has been previously associated with tumor tumorigenesis. However, its mechanism of action in CRC remains unclear. Here, we found that WDR74 expression was upregulated in CRC tissues and cells. Downregulation of WDR74 repressed the proliferation and cell cycles in CRC cells. In addition, WDR74 knockdown induced cell apoptosis and suppressed both cell metastasis and invasion. Mechanistically, WDR74 decreased the phosphorylation of β-catenin and induced nuclear β-catenin accumulation, activating the Wnt/β-catenin signaling pathway in CRC cells. Further investigation showed that blocking the Wnt/β-catenin signaling pathway by XAV-939 reversed the effects of WDR74 on cell proliferation, migration, and invasion in HCT116 cells. Overall, WDR74 induced β-catenin translocation to the nucleus and activated the Wnt/β-Catenin, thus facilitated CRC cell proliferation and metastasis. In summary, WDR74 could be a potential target for the intervention of CRC.
