Regulation of Id2 Gene Expression by the Type 1 IGF Receptor and the Insulin Receptor Substrate-1 [PDF]
Endocrinology, 2001 The Id family of helix-loop-helix proteins is known to be involved in the proliferation and differentiation of several types of cells. The type 1 IGF receptor (IGF-IR) induces either proliferation or differentiation in 32D cells, a murine hemopoietic cell line, depending on the availability of the appropriate substrates for the receptor.

Does reduced IGF-1R signaling in Igf1r+/- mice alter aging? [PDF]
PLoS ONE, 2011 Mutations in insulin/IGF-1 signaling pathway have been shown to lead to increased longevity in various invertebrate models. Therefore, the effect of the haplo-insufficiency of the IGF-1 receptor (Igf1r(+/-)) on longevity/aging was evaluated in C57Bl/6 ...

Expression of mRNA encoding IGF-I, IGF-II and type 1 IGF receptor in bovine ovarian follicles [PDF]
Journal of Endocrinology, 2000 IGFs regulate gonadotrophin-stimulated proliferation and differentiation of granulosa and theca cells in vitro. However, the detailed pattern of mRNA expression of IGFs in bovine follicles remains controversial. The objectives of this study were therefore to describe the temporal and spatial pattern of expression of mRNA encoding IGF-I, IGF-II and the ...

IGF-IR internalizes with Caveolin-1 and PTRF/Cavin in HaCat cells. [PDF]
PLoS ONE, 2010 BACKGROUND:Insulin-like growth factor-I receptor (IGF-IR) is a tyrosine kinase receptor (RTK) associated with caveolae, invaginations of the plasma membrane that regulate vesicular transport, endocytosis and intracellular signaling.

Role of ubiquitination in IGF-1 receptor signaling and degradation. [PDF]
PLoS ONE, 2007 BACKGROUND: The insulin-like growth factor 1 receptor (IGF-1R) plays numerous crucial roles in cancer biology. The majority of knowledge on IGF-1R signaling is concerned with its role in the activation of the canonical phosphatidyl inositol-3 kinase ...

Defective insulin secretion in pancreatic β cells lacking type 1 IGF receptor [PDF]
Journal of Clinical Investigation, 2002 Defective insulin secretion is a feature of type 2 diabetes that results from inadequate compensatory increase of beta cell mass and impaired glucose-dependent insulin release. beta cell proliferation and secretion are thought to be regulated by signaling through receptor tyrosine kinases.

Insulin-Like Growth Factor (IGF) Binding Protein-3 Inhibits Type 1 IGF Receptor Activation Independently of Its IGF Binding Affinity [PDF]
Endocrinology, 2001 Insulin-like growth factor binding proteins (IGFBPs) regulate the cellular actions of the IGFs owing to their strong affinities, which are equal to or stronger than the affinity of the type 1 IGF receptor (IGF-IR), the mediator of IGF signal transduction.
