To figure out the mechanism underlying the tumor-suppressive effect of FTO expression on BCa cells, we detected the expressions of the known differentially m6A methylated genes, including MALAT1 [12], CSNK2A2 [20], ITGA6 [21], and NOTCH1 [22], which were found to correlate with BCa progression in previous studies. The gene discussed is CSNK2A2; the disease is neoplasm.
