Expression of vascular Notch ligands Delta‐like 4 and Jagged‐1 in glioblastoma

Abstract

In summary, Dll4 and Jag1 are expressed in glioblastoma vasculature. These data may define subsets of glioblastoma that might be sensitive (Dll4(+) /Jag1(+) ) or resistant (Dll4(+) /Jag1(-) ) to bevacizumab. Our data also suggest that anti-Dll4 therapy should be evaluated experimentally in glioblastoma.
