IGF2 and neoplasm: Insulin‐like growth factor 2 mRNA‐binding protein 2 (IGF2BP2) is encoded by the IGF2BP2 gene and acts as an RNA‐binding protein of IGF2 mRNA.18 Functions of IGF2BP2 are associated with insulin resistance, lipid metabolism, and tumorigenesis.19, 20 Dai et al21 reported that IGF2BP2 is a tumor promoter, which drives tumor proliferation through HMGA1 and mRNAs IGF2.
