NCIt definition : A humanized monoclonal antibody directed against human heparin-binding EGF-like growth
factor (HBEGF) with potential antineoplastic activity. Anti-HBEGF monoclonal antibody
U3-1565 binds to HBEGF and blocks the binding of HBEGF to the EGF receptors. This
prevents EGF receptor activation and the subsequent induction of cell growth signaling.
HBEGF is mitogenic for fibroblasts and smooth muscle and may be involved in macrophage-mediated
cellular proliferation.;
