The aim of this study is to explore if activation of the insulin receptor with such an optimized peptide (S597) leads to the same activation of signaling pathways and biological endpoints i.e. stimulation of glycogen synthesis and cell proliferation as stimulation with insulin. We find that surface activation of the insulin receptor A-isoform with S597 leads to activation of protein kinase B (PKB) and glycogen synthesis comparable to activation by insulin, even though the level of insulin receptor phosphorylation is lower. In contrast, both Src homology 2/alpha collagen-related (Shc) and extracellular signal-regulated kinase (ERK) 2 activation are virtually absent upon stimulation with S597. Cell proliferation is only stimulated slightly by S597, suggesting that it depends on signals from Shc and ERK. The differences in signaling response could explain both the earlier reported differences in gene expression, and the reported differences in cell proliferation and glycogen synthesis induced by insulin and S597. In conclusion, despite binding equipotency, insulin, and S597 initiate different signaling and biological responses through the same insulin receptor isoform. We show for the first time that it is possible to design insulin receptor ligand mimetics with metabolic equipotency but low mitogenicity."xsd:string |
