BRD7 and nasopharyngeal carcinoma: To gain a deeper insight into the correlation and clinical significance between BRD7 expression and promoter methylation levels in NPC, we detected the methylation status of CpG island region of BRD7 promoter and BRD7 expression in 12 non‐cancerous NP patients and 45 NPC patients at different stages using qMSP and IHC, respectively.
