Role of hypoxia-inducible factors in epigenetic regulation via histone demethylases.
Eukaryotic chromatin is subject to multiple posttranslational histone modifications such as acetylation, methylation, phosphorylation, and ubiquitination. These various covalent modifications have been proposed to constitute ...
The potential of new tumor endothelium-specific markers for the development of antivascular therapy.
Angiogenesis is a hallmark of solid tumors, and disruption of tumor vasculature is an active anticancer therapy in some cases. Several proteins expressed on the surface of tumor endothelium have been identified during the ...
Crosstalk of VEGF and Notch pathways in tumour angiogenesis: therapeutic implications.
Angiogenesis is regulated by a number of angiogenic factors through many signalling pathways. The VEGF pathway and Notch signalling are perhaps two of the most important mechanisms in regulation of embryonic vascular ...
Contrasting properties of hypoxia-inducible factor 1 (HIF-1) and HIF-2 in von Hippel-Lindau-associated renal cell carcinoma.
Defective function of the von Hippel-Lindau (VHL) tumor suppressor ablates proteolytic regulation of hypoxia-inducible factor alpha subunits (HIF-1alpha and HIF-2alpha), leading to constitutive activation of hypoxia pathways ...
Notch signaling from tumor cells: A new mechanism of angiogenesis
(Elsevier BV, 2005-07)
Up-regulation of the Notch ligand Delta-like 4 inhibits VEGF-induced endothelial cell function
(American Society of Hematology, 2006-02-01)
<jats:title>Abstract</jats:title><jats:p>Delta-like 4 (Dll4), a membrane-bound ligand for Notch1 and Notch4, is selectively expressed in the developing endothelium and in some tumor endothelium, and it is induced by vascular ...
Up-regulation of delta-like 4 ligand in human tumor vasculature and the role of basal expression in endothelial cell function.
The Notch signaling pathway and the delta-like 4 ligand (DLL4) play key roles in embryonic vascular development. Many of the pathways involved in embryonic vascular development also play important roles in tumor angiogenesis. ...
Nuclear and membrane expression of the angiogenesis regulator delta-like ligand 4 (DLL4) in normal and malignant human tissues.
AIMS: Delta-like ligand 4 (DLL4) is one of five known Notch ligands in mammals and interacts predominantly with Notch 1. DLL4 is induced by vascular endothelial growth factor (VEGF) and acts downstream of VEGF as a 'brake' ...
Expression of delta-like ligand 4 (Dll4) and markers of hypoxia in colon cancer.
BACKGROUND: Delta-like ligand 4 (Dll4) is a Notch ligand that is upregulated by hypoxia and vascular endothelial growth factor-A (VEGF-A) and is reported to have a role in tumor angiogenesis. Evidence from xenograft studies ...
Regulation of multiple angiogenic pathways by Dll4 and Notch in human umbilical vein endothelial cells.
The Notch ligand, Dll4, is essential for angiogenesis during embryonic vascular development and is involved in tumour angiogenesis. Several recent publications demonstrated that blockade of Dll4 signalling inhibits tumour ...
