Target Information
Delta-like ligand 4 (DLL4), also known as Delta-4, is a transmembrane ligand for the Notch1 receptor and plays a key role in vascular development.
It is induced by VEGF and acts as a negative feedback regulator in angiogenic sprouting, promoting a differentiated vascular network.
DLL4 is strongly expressed in tumor vessels of clear-cell renal tumors and bladder cancer.
Inhibition of DLL4 leads to increased vascular proliferation but defective maturation, resulting in reduced tumor growth without apparent toxicity.
For Research Use Only.
Not for use in diagnostic procedures.
Not for resale without express authorization.
