Fig. 3. FAS regulates OSCC stemness through NOTCH signaling pathways.
A Global mRNA expression in FAS−/− SAS cells analyzed by an Affymetrix U133 cDNA microarray. The significantly differentially expressed genes (fold change = 2) were further analyzed by IPA upstream regulator in z-score to reveal the differential signaling pathways in FAS−/− cells. B Promoter reporter assays of cancer-related signaling pathways between control and FAS−/− SAS cells. C JAG1 mRNA expression level in control and FAS−/− SAS cells. D JAG1 mRNA expression in OSCC patients E Pearson correlation analysis of FAS and JAG1 mRNA expression in OSCC patients. F The CSC sphere formation assay in FAS−/− SAS cells with or without restoration of the NOTCH1-ICD. Scale bar: 100 μm.
