IGF2BP1 and nonpapillary renal cell carcinoma: LINC01426 interacts with insulin-like growth factor 2 mRNA binding protein 1 (IGF2BP1) to enhance expression of CTBP1 in cytoplasm and promote the binding of CTBP1 to the promoter of miR-423-5p in the nucleus to recruit HDAC2 to synergistically inhibit the expression levels of miR-423-5p, leading to an elevation of expression levels of FOXM1 and a promotion of proliferation and migration of ccRCC cells (28).
