Delta-like 4

delta4, Dlx2, Dll4
This gene is a homolog of the Drosophila delta gene. The delta gene family encodes Notch ligands that are characterized by a DSL domain, EGF repeats, and a transmembrane domain. [provided by RefSeq, Jul 2008] (from NCBI)
Top mentioned proteins: CAN, HAD, ACID, AGE, fibrillin-1

Review
New
Vidal-Puig et al., Córdoba, Spain. In Biochim Biophys Acta, 02 Nov 2014
Here, we describe its function, its dysregulation by factors such as oxidative stress, hypoxia and inflammation and provide evidence indicating that dihydroceramides constitute a biologically active molecule from the sphingolipid family with certain differential characteristics with respect to its delta-4 unsaturated counterparts the ceramides.
Mechanisms regulating GABAergic neuron development.
Review
New
Partanen et al., Heidelberg, Germany. In Cell Mol Life Sci, Apr 2014
By comparing the molecular regulation of these events across CNS, we broadly identify three regions utilizing distinct molecular toolkits for GABAergic fate determination: telencephalon-anterior diencephalon (DLX2 type), posterior diencephalon-midbrain (GATA2 type) and hindbrain-spinal cord (PTF1A and TAL1 types).
Notch2 controls prolactin and insulin-like growth factor binding protein-1 expression in decidualizing human stromal cells of early pregnancy.
New
Knöfler et al., Vienna, Austria. In Plos One, Dec 2013
Immunofluorescence of first trimester decidual tissues revealed expression of Notch2 receptor and its putative, membrane-anchored interaction partners Jagged1, Delta-like (DLL) 1 and DLL4 in stromal cells whereas other Notch receptors and ligands were absent from these cells.
A core human primary tumor angiogenesis signature identifies the endothelial orphan receptor ELTD1 as a key regulator of angiogenesis.
New
Impact
Buffa et al., Oxford, United Kingdom. In Cancer Cell, Sep 2013
This approach identified ELTD1, an orphan G-protein-coupled receptor whose expression is induced by VEGF/bFGF and repressed by DLL4 signaling.
Robustness in angiogenesis: notch and BMP shaping waves.
Review
New
Zwijsen et al., Leuven, Belgium. In Trends Genet, Mar 2013
In particular, we focus on how Delta-like ligand 4 (DLL4)-Notch and BMP effector interplay may drive nonsynchronized oscillatory gene expression in ECs essential for setting sharp tip-stalk cell boundaries while sustaining a dynamic pool of nonsprouting ECs.

One of the most prominent factors considered as a promising target in such therapy is the Notch ligand Delta-like 4 (DLL4).

Impact
Adams et al., Münster, Germany. In Nature, 2012
Signalling triggered by VEGF-A (also known as VEGF) has been shown to induce expression of the Notch ligand DLL4 in angiogenic vessels and, most prominently, in the tip of endothelial sprouts.
Synergistic, context-dependent, and hierarchical functions of epithelial components in thymic microenvironments.
Impact
Boehm et al., Germany. In Cell, 2012
Thymic epithelium that lacks hematopoietic function but is physiologically accessible for hematopoietic progenitor cells is functionalized by individual and combinatorial expression of four factors, the chemokines Ccl25 and Cxcl12, the cytokine Scf, and the Notch ligand DLL4.

Acetylation-dependent regulation of endothelial Notch signalling by the SIRT1 deacetylase.
Impact
Potente et al., Frankfurt am Main, Germany. In Nature, 2011
Consequently, endothelial cells lacking SIRT1 activity are sensitized to Notch signalling, resulting in impaired growth, sprout elongation and enhanced Notch target gene expression in response to DLL4 stimulation, thereby promoting a non-sprouting, stalk-cell-like phenotype.

Impact
Baker et al., Leiden, Netherlands. In Nat Cell Biol, 2010
The Tel-CtBP complex temporally restricts a VEGF (vascular endothelial growth factor)-mediated pulse of dll4 expression and thereby directly links VEGF receptor intracellular signalling and intercellular Notch-Dll4 signalling.
