Figure 5. IL-6 promotes NPC cell proliferation in vitro. (A) Cell proliferation of CNE-1 cells in vitro; (B) Cell proliferation of SUNE1 cells in vitro; *p < 0.05 vs. the blank group; #p < 0.05 vs. the IL-6 + AG490 group. The experiment in each group was repeated three times. Abbreviations: NC, negative control; IL-6, interleukin-6; NPC, nasopharyngeal carcinoma.
