The insulin-like growth factor 1 (IGF-1) receptor is a protein found on the surface of human cells. It is a transmembrane receptor that is activated by a hormone called insulin-like growth factor 1 and by a related hormone called IGF-2. It belongs to the large class of tyrosine kinase receptors. This receptor mediates the effects of IGF-1 ...

Signalling through the IGF-1R is the principal pathway responsible for somatic growth in fetal mammals, while somatic growth in postnatal animals is achieved through the synergistic interaction of growth hormone (GH) and the IGFs.

2003年11月6日 · The vascular insulin-like growth factor (IGF)-1 system includes the IGFs, the IGF-1 receptor (IGF-1R), and multiple binding proteins. This growth factor system exerts multiple physiologic effects on the vasculature through both endocrine and …

Insulin-like growth factor-2 (IGF-2) is a protein closely related to IGF-1 and capable of binding to the IGF-1R as well as its own IGF-2 receptor (IGF-2R). However, whilst the IGF-1R is capable of signal transduction, the IGF-2R is not and binding results in lysosomal degradation of IGF-2.

2019年10月8日 · Type 1 insulin-like growth factor receptor (IGF1R) is a receptor tyrosine kinase that regulates cell growth and proliferation, and can be activated by IGF1, IGF2, and insulin. Here,...

In this review, the well-established IGF1 receptor signaling pathways required for the induction of various bioactivities of IGFs are introduced. In addition, we will discuss how IGF signals are modulated by the other extracellular stimuli or by themselves based on our studies.

It is clear that IGF1 is important in supporting growth and regulating metabolism. The IGF1 found in the circulation is primarily produced by the liver hepatocytes, but healthy mature hepatocytes do not express appreciable levels of the IGF1 receptor (IGF1R).

IGF1R stimulates autophagy, enhances viability, and promotes insulin secretion in pancreatic beta cells in gestational diabetes mellitus by upregulating ATG7. Exosomal miR-223 promotes ARDS by targeting insulin-like growth factor 1 receptor: A cell communication study.

The type 1 insulin-like growth factor receptor (IGF-1R), a transmembrane tyrosine kinase, is widely expressed across many cell types in foetal and postnatal tissues.

Type I insulin-like growth factor receptor (IGF-1R) has long been recognized for its role in tumorigenesis and growth, but only recently have the tools for targeting the IGF pathway become available.
