Next, to verify whether m6A methylation of CBX1 mRNA affects CBX1 mRNA expression in NPC, we first analyzed the correlations between the mRNA expression levels of CBX1 and common m6A regulators using the transcriptome data for NPC cells at single‐cell resolution from our previous study (GSE150430).[17] Notably, the expression of members of the YTH domain family showed relatively high correlations with that of CBX1 (Figure S1C, Supporting Information). Here, CBX1 is linked to nasopharyngeal carcinoma.
