TRIM26 and nasopharyngeal carcinoma: Natural killer cells are a main component of PBMCs51 and participate in innate immune responses against viruses and tumors.52, 53, 54 In the NK‐mediated killing assays cocultured with NPC cells, we did observe that silencing of TRIM26 not only directly attenuated NK cell cytotoxicity but also reduced the sensitization of NPC cells to NK‐mediated killing (Figure S7).
