Additionally, recent research indicates that BRD7 can downregulate PD‐L1 expression by inhibiting the PI3K/AKT/mTOR/STAT3 signalling pathway, thereby enhancing the cytotoxic function of CD8+ T cells and suppressing immune evasion in NPC, which in turn inhibits tumour growth.50 This evidence concerns the gene AKT1 and nasopharyngeal carcinoma.
