Compared to normal tissue samples, the expression levels of RBMX, YTHDF1, IGF2BP3, IGF2BP2, and HNRNPC were significantly increased in tumor tissue samples, while the expression of KIAA1429, YTHDF2, ZC3H13, METTL14, IGF2BP1, and ALKBH5 in normal tissues was significantly higher than that in PRCC tissues (Figure 2B). The gene discussed is IGF2BP2; the disease is neoplasm.
