NANOG is also able to regulate the expression of BMI1, TWIST1, and SNAIL1 to promote EMT, invasion, migration, the induction of stemness markers, metastasis, and tumor-initiating ability in breast, colon, non-small cell lung cancer (NSCLS), and head and neck squamous cell carcinoma (HNSCC) via promoter occupancy [25,26]. Here, SNAI1 is linked to neoplasm.
