Consistent with these observations, we found that CBX1 expression in NPC cells was positively correlated with the proportion of exhausted CD8+ T cells by analyzing our single‐cell RNA‐seq data reported previously (GSE150430, Figure S2N, Supporting Information).[17] These results demonstrated that targeting CBX1 could inhibit NPC cell migration, invasion and proliferation and enhance the antitumor immune response in NPC. Here, CBX1 is linked to nasopharyngeal carcinoma.
