NCIt definition : A monoclonal antibody directed against the human alpha5beta1 integrin with potential
antiangiogenic and antineoplastic activities. Anti-alpha5beta1 integrin monoclonal
antibody PF-04605412 selectively binds to alpha5beta1 integrin, preventing the binding
of integrin ligands. This may result in the inhibition of endothelial cell-cell interactions,
endothelial cell-matrix interactions, and integrin-mediated tumor angiogenesis and
metastasis in alpha5beta1-expressing tumor cells. Alpha5beta1 integrin, a cell adhesion
and signaling receptor, is often overexpressed on the surface of tumor vessel endothelial
cells and plays a crucial role in endothelial cell adhesion and migration.;
