Vascular Endothelial Growth Factor Receptor 1 (VEGF-R1)

Part Description

It is vascular endothelial growth factor receptor which contain 3 members contain similar structures and their external parts are made up entirely of repeating segments that resemble parts of antibodies (immunoglobulin homology repeats) and they have a critical role in the formation of blood vessels and lymphatic vessels.

Usage

This is the extracellular domain of DocTAR receptor which respond specifically to vascular endothelial growth factor (VEGF) which is a specific substance for wounds so when activated it transduce the signal causing dimerization of the two receptor chains and thus help in the control of transcription and prevent auto activation.

Literature Characterization

In this study, a group of 34 angiosarcomas were examined using immunohistochemistry technique which allowed to assess the levels of proteins involved in blood vessel growth, including vascular endothelial growth factors (VEGF-A and VEGF-C) and their corresponding receptors (VEGFR-1, VEGFR-2, and VEGFR-3).

VEGF-A was expressed by 32/34 (94%), VEGF-C by 4/34 (12%), VEGFR-1 by 32/34 (94%), VEGFR-2 by 22/34 (65%), and VEGFR-3 by 27/34 (79%) .

The figure shows immunohistochemical staining of proteins associated with blood vessel growth in angiosarcoma scalp tissue. Panel A reveals strong positivity for VEGF-A in tumor cells. Panels B and C demonstrate consistent positivity for VEGFR-1 and VEGFR-3, respectively, in the lining of tumor cells. Panel D shows VEGF-C expression within the angiosarcoma, surrounded by lighter areas containing lymphocyte immune cells.
