NSUN2 and retinoblastoma: To explore the mechanism by which NSUN2 promotes the pathogenesis of RB, we performed multiomics analyses to determine potential RNA targets of NSUN2, including transcriptome analysis (RNA‐seq; Figure 3A, B, deposited in GSE214685), proteomic analysis (isobaric tags for relative and absolute quantitation [iTRAQ]; Figure 3C, D and Table S3) and m5C‐IP‐seq (Figure 3E, F).
