Objective: To investigate the effects and molecular mechanism of Yiqi Jiedu Decoction (YQ) combined with salinomycin (SAL) on the proliferation of nasopharyngeal carcinoma stem cells. Methods: Nasopharyngeal carcinoma stem cells CNE2-SC and 5-8F-SC were obtained and treated with YQ, SAL alone or in combination. Cell counting methods, plate clonality assays were used to measure the impact of drugs on proliferation and colony forming ability of stem cells, and Western Blot were used to test detect the expression level of related proteins. Results: Both YQ and SAL significantly inhibited the prol...
