Recombinant Insulin-Like Growth Factor

Definition 1

A recombinant human antiapoptotic growth factor. Recombinant insulin-like growth factor (IGF) binds to and activates the insulin and IGF receptors; activation of these receptors initiates intracellular phosphorylation events and the activation of several signaling pathways, thereby promoting cellular proliferation and inhibiting apoptosis. High levels of circulating endogenous insulin-like growth factor may indicate a poor prognosis in some cancers. (NCI Thesaurus)

Definition 2

Insulin-like polypeptides made by the liver and some fibroblasts and released into the blood when stimulated by SOMATOTROPIN. They cause sulfate incorporation into collagen, RNA, and DNA synthesis, which are prerequisites to cell division and growth of the organism. (NLM, Medical Subject Headings)
