DNMT1 and neoplasm: Further assessments were performed for determining these genes’ differential expressions in cancerous and non-cancerous tissues in the TCGA and CPTAC databases, revealing that YTHDF1, DNMT1, NSUN4, NOP2, ALYREF, WTAP and HNRNPC demonstrated notable upregulation in tumor tissues at both the protein and RNA levels and could be promising targets for further investigation (Fig. S7B–G).
