一般描述
Insulin-like growth factor-I (IGF-I) is encoded by the gene mapped to human chromosome 12q23.2. IGF-I belongs to insulin-like growth factor (IGF) family. The encoded protein is ubiquitously expressed, but the circulating form of the protein is mainly found in liver and pancreas.
免疫原
purified, E. coli-derived recombinant human insulin-like growth factor-I.
应用
Anti- IGF-1 antibody may be used for neutralization reactions, the ND50 of the antibody is 3-12 μg/ml. For immunoblotting a working antibody concentration of 0.1-0.2 μg/ml. The recommended antibody concentration for immunocytochemistry is 5-15 μg/ml. The antibody is suitable for immunohistochemistry of formalin-fixed, paraffin-embedded sections.
生化/生理作用
Insulin-like growth factors -1 and -2 are important regulators of signalling that mediates growth and metabolism in cells. Insulin-like growth factor -1 shares structural homology with proinsulin and is mainly produced by liver. IGF-1 acts via specific receptor, IGF-1R, a heterodimeric tyrosine kinase receptor that signals to various second messenger pathways such as MAPK, Raf/Ras and PI3K cascades. The effect of IGF-1 is by endocrine, paracrine and autocrine signalling. The effects of IGF-1 signalling are important at many developmental levels from cells to organ to organism, growth, differentiation, anti-apoptosis, proliferation and transformation. Irregular IGF-1 signaling has been implicated in many cancers including melanoma, breast, lung, colon and prostate. Anti-IGF-I recognizes human insulin-like growth factor I.

Insulin-like growth factors (IGFs), in particular IGF-I and IGF-II, strongly stimulate the proliferation of a variety of cancer cells, including those from lung cancer. To examine the possible causal role of IGFs in lung cancer development, we compared plasma levels

Insulin-like growth factor-I (IGF-I) is a mitogen for prostate epithelial cells. To investigate associations between plasma IGF levels and prostate cancer risk, a nested case-control study within the Physicians' Health Study was conducted on prospectively collected plasma from 152 cases

The insulin receptor (IR) and the insulin-like growth factor I receptor (IGF-IR) belong to the same subfamily of receptor tyrosine kinases with two extracellular alpha-subunits and two transmembrane beta-subunits. They share a high similarity of structure and intracellular signalling events.
