NCIt definition : A humanized monoclonal antibody directed against the N-terminal epitope of Notch ligand
DLL4 (delta-like 4) with potential antineoplastic activity. Demcizumab binds to the
membrane-binding portion of DLL4 and prevents its interaction with Notch-1 and Notch-4
receptors, thereby inhibiting Notch-mediated signaling and gene transcription, which
may impede tumor angiogenesis. Activation of Notch receptors by DLL4 stimulates proteolytic
cleavage of the Notch intracellular domain (NICD); after cleavage, NICD is translocated
into the nucleus and mediates the transcriptional regulation of a variety of genes
involved in vascular development. The expression of DLL4 is highly restricted to the
vascular endothelium.;
