Insulin‐like growth factor‐binding protein‐2 inhibits proliferation of human embryonic kidney fibroblasts and of IGF‐responsive colon carcinoma cell lines
4 Sept 1998
Abstract excerpt
So far, the physiological role of insulin-like growth factor binding protein-2 (IGFBP-2) has not been demonstrated directly. Therefore, we transfected 293 cells with an expression vector containing the CMV promoter and the complete cDNA of mouse IGFBP-2. Secretion of bioactive IGFBP-2 into conditioned medium was demonstrated by Western ligand and Western immunoblotting and quantified by specific RIA. For the...
