Of these regulators, the expression of METTL3 (P<0.001), HNRNPC (P<0.01), YTHDF2 (P<0.01) and YTHDF1 (P<0.001) in BC tissues was significantly higher than that in normal tissues, and the expression of ZC3H13 (P<0.01) and FTO (P<0.01) in normal tissues was significantly higher than that in BC tissues (Figure 1). The gene discussed is HNRNPC; the disease is breast cancer.
