Knockdown of PIMREG modulates the Wnt/β-catenin pathway to suppress proliferation and stemness in endometrial cancer

Background: Endometrial cancer is the most common gynecological malignancy, and poses serious threat to health. PIMREG (PICALM interacting mitotic regulator also known as FAM64A), has been uncovered in promoting tumorigenesis in multiple cancers. But, its regulatory impacts in endometrial cancer remain poorly understood. Methods: Cell viability was assessed by the Cell Counting Kit-8 (CCK-8) assay. Protein levels were inspected by Western blotting. Cell proliferation was evaluated by colony formation assay, while stemness was examined by sphere formation assays. Results: PIMREG expression was found to be upregulated in endometrial cancer. Suppression of PIMREG significantly reduced cell viability and suppressed proliferative and stemness capacities. Furthermore, silencing PIMREG retarded the evoking of the Wnt/β-catenin signaling pathway. Conclusions: PIMREG knockdown suppressed proliferation and stemness by modulating the Wnt/β-catenin pathway in endometrial cancer. This project hinted that PIMREG may be one useful therapeutic target for endometrial cancer treatment.
