Research Abstract |
Malignant phenotype of Head and Neck Cancer (HNC) is related to EMT and polycomb gene induction, and emerging evidence suggests a role of EMT/Polycombs on Cancer stem cell (CSC) induction. In this study, we investigated whether EMT and polycomb genes control CSC of HNC cells. Forced expression of the Bmi1, EZH2 and Slug in HNC cell lines induced cancer stemness phenotypes, such as ALDH1 activity. Two inflammatory cytokines, TGFb and TNFa potentiated Bmi1-related CSC phenotypes. These results suggest that polycomb and EMT genes under inflammatory environment regulate malignant phenotypes of HNC.
