As shown in Figure 2B, 2 upregulated (IGF2BP2 and IGF2BP3) and 5 downregulated (METTL3, ALKBH1, YTHDF2, YTHDF3, and heterogeneous nuclear ribonucleoprotein C [HNRNPC]) m6A‐related genes in T2DM samples were found to be significantly associated with the occurrence of T2DM compared to nondiabetes samples. This evidence concerns the gene HNRNPC and type 2 diabetes mellitus.
