the Notch signaling and atherosclerosis relevant markers in lesions from femoral arteries of symptomatic peripheral artery disease patients, were characterized.
Data suggest that Numb acts as a Notch antagonist by controlling intracellular destination and stability of the Notch ligand Delta-like 4 (DLL4) through a post-endocytic sorting process; Numb negatively controls DLL4 plasma membrane recycling through well-documented recycling regulator protein AP1.
Results show that DLL4 is involved in SYNJ2BP-induced hepatocellular carcinoma (HCC) development though activating its pathway.
Positive Jagged1 and DLL4 expression is closely correlated with severe clinicopathological characteristics and poor prognosis in patients with gallbladder cancers.
We show that GIT1, which also contains an ANK domain, inhibits the Notch1-Dll4 signaling pathway by competing with Notch1 ANK domain for binding to RBP-J in stalk cells
Results provide evidence that DLL4 is associated with gastric cancer stem/progenitor cells (GCSPCs), and its expression impacts CSPC stemness characteristics associated with the Notch-1 pathway including self-renewal, differentiation, proliferation, and tumor formation.
The authors present novel structures of human ligands Jagged2 and Delta-like4 and human Notch2, together with functional assays, which suggest that ligand-mediated coupling of membrane recognition and Notch binding is likely to be critical in establishing the optimal context for Notch signalling.
Overexpression of DLL4 could significantly attenuate the cytotoxic effects of docetaxel in MCF-7 cells by increasing Bcl-2 expression, while decreasing Bax expression, apoptosis rate and DNA damage
In gastric epithelial cells co-cultured with Helicobacter pylori, the expression level of the ligand DLL4 was found to be significantly increased.
Low DLL4 abundance in tumour cells may predict the benefit from adjuvant gemcitabine therapy after PDAC resection.
Angiogenesis in Infantile haemangioma (IH) appears to be controlled by DLL4 within the endothelium in a VEGF-A isoform-dependent manner, and in perivascular cells in a VEGF-independent manner. The contribution of VEGF-A isoforms to disease progression also indicates that IH may be associated with altered splicing.
Notch signaling mediated by Dll1 and Dll4 is necessary for the development and persistence of chronic graft-versus-host disease.
repressed Dll4-Notch1 signaling pathway but not downregulation of VEGF-A expression are responsible for hyperoxia induced pervasive vessel regression.
this study shows that DLL4 induces epigenetic regulation of Treg cell differentiation and function in viral infection
Collectively, these data show that DLL4 preferentially activates NOTCH1 over NOTCH2, whereas DLL1 is equally effective in activating NOTCH1 and NOTCH2, establishing that the ectodomains dictate selective ligand function in vivo, and that features outside the known binding interface contribute to their differences.

Data suggest that endothelial specific Delta-like 4 (Dll4) overexpression appears as a promising anti-angiogenic modality that might improve cancer control.
Dll4 seems to promote Apc (Min/+) tumorigenesis.
Dll4-Notch1 signalling couples sprouting angiogenesis and artery formation.
Results suggest that Dll4 activation during differentiation sustained Treg cell phenotype and function to control respiratory syncytial virus infection.
DLL4 expression is not associated with the Pathogenesis of Non-Alcoholic Steatohepatitis.
The results demonstrate that the Vegf-Dll4/Notch feedback system normally operates to generate heterogeneity between endothelial cells driving blood vessel branching, whilst synchronization drives vessel expansion.
