In the human cell line nasopharyngeal carcinoma (CNE2 cells), mangiferin different concentrations are (12.5, 25, 50, 100, 150 and 200 μM) suppressed CNE2 cell proliferation via G2/M phase cell cycle arrest, induced early apoptosis, downregulated the mRNA and protein levels of Bcl-2, and upregulated Bax [44]. This evidence concerns the gene BCL2 and nasopharyngeal carcinoma.
