In the study of head and neck squamous cell carcinoma, it was found that Radix Astragali induced apoptosis in nasopharyngeal carcinoma cells, as evidenced by the elevated levels of cysteinyl asparaginase and Bax protein and the decreased level of Bcl-2 protein21, and APS significantly promoted the antiproliferative and apoptotic effects of cisplatin on nasopharyngeal carcinoma cells22. This evidence concerns the gene BAX and nasopharyngeal carcinoma.
