Based on the central role of the IGF-I receptor in the regulation of cell proliferation, this article systematically elucidates the mechanism by which IGF-I peptide analogs block signal transduction by inhibiting receptor autophosphorylation, analyzes experimental evidence of their growth inhibition in prostate cancer cells and SV40-transformed cells, and explores the potential value of such analogs as research tools for signaling pathways and as anti-tumor therapeutic strategies.

Insulin-like growth factor-I is a peptide growth factor structurally homologous to insulin, playing a central regulatory role in physiological processes such as cell proliferation, differentiation, metabolism, and survival.
