Moreover, high coexpression of UBE2C/CD44, UBE2C/CD166 and UBE2C/EpCAM genes (Table 3) was associated with overall survival and recurrence in oral cancer patients including TSCC patients from TCGA database, indicating that UBE2C might be involved in controlling cancer stemness of OSCC. This evidence concerns the gene EPCAM and lip and oral cavity carcinoma.
