Principle of the Assay: This kit was based on sandwich enzyme-linked immune-sorbent assay technology. Anti- IGFBP7 polyclonal antibody was pre-coated onto 96-well plates. And the biotin conjugated anti- IGFBP7 polyclonal antibody was used as detection antibodies. The standards, test samples and biotin conjugated detection antibody were added to the wells subsequently, and wash with wash buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with wash buffer. TMB substrates were used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the IGFBP7 amount of sample captured in plate. Read the O.D. absorbance at 450nm in a microplate reader, and then the concentration of IGFBP7 can be calculated.

Background/Introduction: Insulin-like growth factor-binding protein 7 is a protein that in humans is encoded by the IGFBP7 gene. Lymphangiogenesis is not only involved in the processes of embryonic development, tissue repair and chronic inflammation, but also in tumor lymphatic metastasis. Metastatic tumor cells spreading through lymphatic vessels occur in non-small cell lung carcinoma (NSCLC), with regional lymph node metastasis often being the most important prognostic factor for carcinoma patients. Insulin-like growth factor binding protein 7 (IGFBP7) was proven to be associated with metastatic clinicopathological features and high LVD. Furthermore, by assessing the capability of lymphatic endothelial cell forming lymphatic vessel-like structures in vitro, it appears to enhance lymphangiogenesis. As a very important transcription factor, signal transducer and activator of transcription 5a (Stat5a) has been reported to be involved in human reproductive cancers such as breast, prostate and ovarian cancer. The mitogenic effect of D5 Stat5a on breast cells is, at least partly, through up-regulation of histone methyltransferase, EZH2, and therefore inhibiting IGFBP-7 expression by increasing H3K27Me3 of IGFBP-7 promoter region.

NCBI Description

This gene encodes a member of the insulin-like growth factor (IGF)-binding protein (IGFBP) family. IGFBPs bind IGFs with high affinity, and regulate IGF availability in body fluids and tissues and modulate IGF binding to its receptors. This protein binds IGF-I and IGF-II with relatively low affinity, and belongs to a subfamily of low-affinity IGFBPs. It also stimulates prostacyclin production and cell adhesion. Alternatively spliced transcript variants encoding different isoforms have been described for this gene, and one variant has been associated with retinal arterial macroaneurysm (PMID:21835307).

Uniprot Description

IGFBP7: Binds IGF-I and IGF-II with a relatively low affinity. Stimulates prostacyclin (PGI2) production. Stimulates cell adhesion. Defects in IGFBP7 are the cause of retinal arterial macroaneurysm with supravalvular pulmonic stenosis (RAMSVPS). RAMSVPS is an autosomal recessive condition characterized by the bilateral appearance of 'beading' along the major retinal arterial trunks, with the subsequent formation of macroaneurysms. Affected individuals also have supravalvular pulmonic stenosis, often requiring surgical correction.
