In this study, we have analyzed mice bearing loss-of-function mutations of the insulin/IGF signaling systems. Combined inactivation of insulin receptor (Insr) and Igf1 receptor (Igf1r), but not of either receptor alone, resulted in a 90% decrease in the size of the exocrine pancreas, because of decreased cellular proliferation. In contrast to the findings in the exocrine compartment, endocrine alpha- and beta-cell development was unperturbed. Combined ablation of Igf1 and Igf2, the ligands for these two receptors, resulted in an identical phenotype. We also examined the effect of heterozygous null Igf1r mutations on glucose homeostasis in adult mice. Igf1r haploinsufficiency did not affect insulin action and compensatory beta-cell growth in insulin-resistant mice with combined Insr and Igf1r heterozygous null mutations, resulting in a considerably milder phenotype than combined haploinsufficiency for Insr and its main signaling substrates, Irs1 and Irs2. We conclude that Igf1r and Insr are required for embryonic development of the exocrine but not of the endocrine pancreas and that defects of Igf1r do not alter glucose homeostasis as long as the insulin receptor system remains intact."xsd:string |
