BRD7 and nasopharyngeal carcinoma: In the methylation detection of tumour masses in the xenograft mouse model, it was also found that TET1CD had a very limited demethylation effect on the CpG island region of the BRD7 promoter, indicating that the anti‐tumour effects of TET1CD in NPC are not due to specific targeting of BRD7 for demethylation.
