Supplementary information

DLL4 also known as Delta-like ligand 4 is a member of the Delta/Serrate/Lag-2 family. This target is a single-pass type I membrane protein with a molecular weight of approximately 65 kDa. It features prominently in the vascular endothelium where it impacts angiogenic activity. DLL4 acts as a ligand for Notch receptors initiating a signaling cascade important to cell fate decisions. DLL4 expression occurs mainly on the arterial endothelium and the tumor vasculature highlighting its significance in angiogenesis.
Biological function summary

DLL4 engages in precise regulation of angiogenesis and vascular development. It participates in the Notch signaling pathway playing an integral role in controlling endothelial cell proliferation differentiation and migration. DLL4 does not operate in isolation; instead it functions as part of the Notch receptor-ligand complex. This relationship effectively regulates the sprouting of new blood vessels ensuring proper vascular patterning and functional blood supply.

Pathways

DLL4 links directly to the Notch signaling and VEGF (vascular endothelial growth factor) pathways both of which play critical roles in vascular development and homeostasis. Through the Notch pathway DLL4 interacts with Notch1 and Notch4 receptors facilitating communication that inhibits endothelial cell proliferation distinguishing it from other pro-angiogenic factors. Its relationship with the VEGF pathway allows DLL4 to modulate angiogenic processes balancing vessel sprouting by opposing excessive VEGF-induced activities.

Aberrations of DLL4 influence cancer and cardiovascular diseases. Overexpression and dysregulation of DLL4 have been observed in various cancers where it contributes to tumor angiogenesis promoting the growth and spread of cancer cells. In cardiovascular disorders dysfunctional DLL4 signaling impacts vascular development which can lead to fatal arteriovenous malformations. In these conditions DLL4 interacts with proteins like Notch1 and VEGF underlining its critical involvement in pathological angiogenesis and vessel formation.
