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. This evidence concerns the gene CD8A and nasopharyngeal carcinoma.
