DLL4 / Delta4抗体背景综述
Delta-like protein 4 (DLL4) is a type I membrane-bound Notch ligand characterized by an extracellular region containing several EGF-like domains and a DSL domain required for receptor binding, and is suggested to play a key role in vascular development and tumor angiogenesis. The Notch pathway is an evolutionary conserved intercellular signaling pathway involved in numerous biological processes including cell fate determination, cellular differentiation, proliferation, survival, and apoptosis. In mammalian cells, five Notch ligands (Jagged1, 2, DLL1, 3, 4) and four Notch receptors (Notch1-4) have been identified, and ligand-receptor interactions results in proteolysis and translocation of the Notch intracellular domain. As a ligand for Notch1 and Notch4, DLL4 is sel ectively expressed in the developing endothelium and in some tumor endothelium, and is induced by vascular endothelial growth factor (VEGF)-A and hypoxia. In recent studies, it has been revealed that this DLL4 inhibition may paradoxically lead to increased angiogenesis but poor tumor growth because of the non-functional. neovascularization, and constitutive expression of DLL4 may leads to a lethal lymphoproliferative disease. Accordingly, this may provide a new therapeutic approach for certain carcinomas.
