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)

Serum proteins (Delta-like ligand (DLL4), Notch1, hypoxia inducible factor-1α (HIF-1α), HIF-2α, vascular endothelial growth factor A (VEGFA) and platelet-derived growth factor receptor β (PDGFRB)) levels were measured using enzyme-linked immunosorbent assay (ELISA).
VEGFR3 does not sustain retinal angiogenesis without VEGFR2.
Alitalo et al., Helsinki, Finland. In Proc Natl Acad Sci U S A, 20 Feb 2015
VEGFR2 is abundant in the tip cells of angiogenic sprouts, where VEGF/VEGFR2 functions upstream of the delta-like ligand 4 (DLL4)/Notch signal transduction pathway.
Taking T Cell Priming Down a Notch: Signaling through Notch Receptors Enhances T Cell Sensitivity to Antigen.
Butte et al., Stanford, United States. In Immunity, 20 Feb 2015
(2015) show that Notch interactions with Delta-like ligand 4 (DLL4) amplify priming of naive T cells.
Notch Signaling Regulates Antigen Sensitivity of Naive CD4(+) T Cells by Tuning Co-stimulation.
Fowlkes et al., Bethesda, United States. In Immunity, 20 Feb 2015
We have found that Delta Like Ligand 4 (DLL4)-induced Notch signaling potentiates phosphatidylinositol 3-OH kinase (PI3K)-dependent signaling downstream of the T cell receptor+CD28, allowing naive CD4(+) T cells to respond to lower doses of antigen.
Dihydroceramide desaturase 1, the gatekeeper of ceramide induced lipotoxicity.
Vidal-Puig et al., Córdoba, Spain. In Biochim Biophys Acta, Jan 2015
Here, we describe its function and 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.
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).
A core human primary tumor angiogenesis signature identifies the endothelial orphan receptor ELTD1 as a key regulator of angiogenesis.
Buffa et al., Oxford, United Kingdom. In Cancer Cell, 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.
Zwijsen et al., Leuven, Belgium. In Trends Genet, 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.
