NCIt related terms : Anti-PDGFR Alpha Monoclonal Antibody MEDI-575;
NCIt definition : A humanized monoclonal antibody directed against the platelet-derived growth factor
receptor (PDGFR) alpha with potential antineoplastic activity. Tovetumab inhibits
activation of the cell-surface tyrosine kinase PDGFR alpha subunit and subsequent
triggering of mitogenic signaling pathways, including the JAK/STAT, PI3K/Akt, and
MAP kinase pathways. PDGFR alpha acts as a mitogenic signaling receptor for cells
of mesenchymal origin and inhibition of receptor activity may inhibit tumor cell proliferation.;
