Our analysis showed that treating NPC cultures with PMCM preincubated with TNF-α NA was able to entirely reverse the inhibitory effects of PMCM on NPC proliferation and bring it to a comparable level as NPCs treated with control media or RMCM (p < 0.0001, one-way ANOVA, N = 3 independent cultures) (Figures 4(a)–4(m)). Here, TNF is linked to nasopharyngeal carcinoma.
