Immunohistochemistry-Paraffin: VEGFR1/Flt-1 Antibody [NB100-527]

Immunohistochemistry-Paraffin: VEGFR1/Flt-1 Antibody [NB100-527]

Immunohistochemistry-Paraffin: VEGFR1/Flt-1 Antibody [NB100-527] - Analysis of FFPE human breast carcinoma tissue section using 1:500 dilution of VEGFR1/Flt-1 antibody on a Bond Rx autostainer (Leica Biosystems). The assay involved 20 minutes of heat induced antigen retrieval (HIER) with 10mM sodium citrate buffer (pH 6.0) and endogenous peroxidase quenching using peroxide block. The sections were incubated with primary antibody for 30 minutes. Bond Polymer Refine Detection (Leica Biosystems) and DAB were used for signal detection which followed counterstaining with hematoxylin. Whole slide scanning and capturing of representative images (20X) were performed using Aperio AT2 (Leica Biosystems). This VEGFR1/Flt-1 antibody generated an expected membrane cytoplasmic staining of VEGFR1 protein in the cancer cells (punctate appearance typical of receptors). The tumor stroma/stromal cells did not show VEGFR1/Flt-1immunopositivity.

Background: VEGFR1/Flt-1

VEGF Receptor 1 (vascular endothelial growth factor receptor 1 or VEGFR1; also called Flt1 in mouse) is a tyrosine-protein kinase which acts as a cell-surface receptor for VEGFA, VEGFB and PGF ligands for playing an essential role in the embryonic vasculature development and regulation of angiogenesis (normal as well as cancerous tissues), cell survival, migration, macrophage function, chemotaxis, and tumor invasion. VEGFR1 is a 180-185 kD glycoprotein expressed primarily in vascular endothelial cells and also found in a wide range of non-endothelial cells, such as monocytes and macrophages, human trophoblasts, renal mesangial cells, vascular smooth muscle cells, dendritic cells and different human tumour cell types. Interestingly, VEGFR1 acts as a negative regulator of embryonic angiogenesis by inhibiting excessive proliferation of endothelial cells, whereas it promotes endothelial cell proliferation, survival and angiogenesis in adults. VEGFR1 expression is regulated by hypoxia through HREs in VEGFR1 promoter. It exists in an inactive conformation in the absence of bound ligand and binding of VEGFA, VEGFB or PGF leads to its dimerization followed by tyrosine residue autophosphorylation mediated activation. VEGFR1 phosphorylation sites includes Tyr794, Tyr1169, Tyr1213, Tyr1242, Tyr1327, Tyr1333 etc. and VEGFR1 phosphorylation pattern depends on the ligand, e.g. PlGF, but not VEGFA, induces phosphorylation of Tyr1309. VEGFR1 has been shown to exert its diverse biological activities through its effects on multiple signal transduction pathways including VEGF, KDR, PLCG, PI3K, MAPK etc.
