Thus, we analyzed the N6-methyladenosine (m6A), N1-methyladenosine (m1A), and N6-methylcytosine (m6C) methylation of the CPEB1 (Figure 7A) and COLEC12 mRNAs (Figure 7B) in various cancers, and we discovered that the m6A modification of CPEB1 displayed a stronger correlation with BC than the m5A and m1A modifications of CPEB1, and similar results were obtained for YTHDF1 and YTHDC2. COLEC12 exhibited a stronger association with the m1A and m6A modifications than with the m5C modification in BC. The gene discussed is CPEB1; the disease is breast cancer.
