As Wnt/β-catenin plays a critical in EMT induction and maintenance, we examined the protein expression of the Wnt/β-catenin signaling genes for GSK3β, β-catenin, c-MYC, and cyclin D1 in CNE-2 and SUNE-1 cells overexpressing YPEL3 or in which YPEL3 had been silenced to explore the YPEL3 mechanism underlying NPC metastasis. The gene discussed is MYC; the disease is nasopharyngeal carcinoma.
