The migration of EC cells was assessed by wound-healing and Transwell assays as well as in an in vitro study of nude mice. In addition, the expression of specific proteins was analyzed by Western blot.Results: We observed that SOX17 expression levels were relatively high in stage I EC specimens, and were significantly correlated with the epithelial cadherin (E-cadherin) and β-catenin expression. Additionally, stage II EC patients whose specimens had relatively high SOX17 expression levels had better outcomes. Wound-healing and Transwell assays and in vivo murine experiments revealed that SOX17 inhibited EC cell migration. Meanwhile, SOX17 increased expression of E-cadherin and decreased expression of β-catenin and proteins in the Wnt signaling pathway. Moreover, LiCl (β-catenin activator) enhanced the regulatory effects of SOX17 on the expression of E-cadherin, promigratory cadherin, vimentin, and proteins in the Wnt signaling pathway, while XAV93920 (β-catenin inhibitor) exerted the opposite effect. The SOX17 N-terminus was proved to be necessary for these effects. Mechanistic investigations suggested SOX17 inhibits EC cell migration by inactivating the Wnt/β-catenin–epithelial mesenchymal transition (EMT) axis in EC cells.Conclusion: We uncovered a common SOX17–β-catenin–EMT mechanism underlying EC cell migration.Keywords: SOX17, endometrial cancer (EC), migration, high-mobility group (HMG)https://www.dovepress.com/sox17-inhibits-tumor-metastasis-via-wnt-signaling-in-endometrial-cance-peer-reviewed-article-OTTSOX17endometrial cancer (EC)migrationhigh-mobility group(HMG) |
