NCIt definition : A fully human IgG1 monoclonal antibody directed against the platelet-derived growth
factor receptor alpha (PDGFR alpha) with potential antineoplastic activity. Anti-PDGFR
alpha monoclonal antibody IMC-3G3 selectively binds to PDGFR alpha, .blocking the
binding of its ligand, PDGF; signal transduction downstream of PDGFR through the MAPK
and PI3K pathways is inhibited, which may result in inhibition of angiogenesis and
tumor cell proliferation. Overexpressed by various cancer cell types, PDGFR is a transmembrane
protein tyrosine kinase receptor, consisting of isoforms A and B that is important
in regulating cellular growth and differentiation and angiogenesis.;
Alternative definition : NCI-GLOSS: A substance being studied in the treatment of glioblastoma (a type of brain
tumor) that has come back. It binds to receptors for a protein called platelet-derived
growth factor (PDGF). This keeps PDGF from binding to the cells. This may stop the
growth of cancer cells and blood vessels that have the receptors for PDGF. It is a
type of monoclonal antibody.;
