Integrity of the vascular endothelium is largely dependent on endothelial cell shape and establishment of intercellular junctions. Certain pathogenic bacterial toxins alter the cytoskeletal architecture of intoxicated cells by modulating the GTPase activity of p21 Rho family proteins. In the present study we have analyzed the effect of Rho-directed toxins on the actin cytoskeleton and monolayer...
Human embryonic stem cell-derived endothelial cells (hESC-EC), as well as other stem cell derived endothelial cells, have a range of applications in cardiovascular research and disease treatment. Endothelial cells sense Gram-negative bacteria via the pattern recognition receptors (PRR) Toll-like receptor (TLR)-4 and nucleotide-binding oligomerisation domain-containing protein (NOD)-1. These pat...
BACKGROUND/AIM Previous reports have made it hypothetically possible that human chorionic gonadotropin (hCG) could protect against the onset of pregnancy-related pathological conditions by acting as an antioxidant. In the present study we planned to examine the effects of hCG against oxidative stress in human umbilical vein endothelial cells (HUVEC). METHODS HUVEC were subjected to peroxidati...
The ErbB, or epidermal growth factor receptor (EGF-r), family of transmembrane tyrosine kinase receptors has been demonstrated to play an important role in growth regulation and intracellular signaling in a wide variety of cell types. Targeted deletion of neuregulin (an ErbB ligand) in mice results in endocardial cushion abnormalities, suggesting that these receptor-ligand interactions have imp...
BACKGROUND Thrombospondin type I domain containing 7A (THSD7A) is a novel neural protein that is known to affect endothelial migration and vascular patterning during development. To further understand the role of THSD7A in angiogenesis, we investigated the post-translational modification scheme of THS7DA and to reveal the underlying mechanisms by which this protein regulates blood vessel growth...
Radiation-induced activation of the phosphatidyl inositol-3 kinase/Akt signal transduction pathway requires Akt binding to phosphatidyl-inositol phosphates (PIP) on the cell membrane. The tyrosine kinase bone marrow X kinase (Bmx) binds to membrane-associated PIPs in a manner similar to Akt. Because Bmx is involved in cell growth and survival pathways, it could contribute to the radiation respo...
Previous studies have reported that human vascular endothelial cells lack the membrane-bound lipopolysaccharide (LPS) receptor, CD14 (mCD14). By optimizing assay conditions, including the selection of anti-CD14 monoclonal antibody, we now demonstrate that human umbilical vein endothelial cells (HUVEC) express CD14 on the cell surface. Single-passage HUVEC showed approximately 20 times less expr...
Vascular endothelium activated by endotoxin (lipopolysaccharide [LPS]) and cytokines plays an important role in organ inflammation and blood leukocyte recruitment observed during sepsis. Endothelial cells can be activated by LPS directly, after its interaction with LPS-binding protein and soluble CD14 in plasma. LPS-LPS-binding protein complexes in blood also interact with monocytes and neutrop...
To determine the role of the transcription factor signal transducer and activator of transcription (STAT) 1 on endothelial cell function, human umbilical vein endothelial cells (HUVEC) were treated with IFN-gamma, a potent activator of STAT1. IFN-gamma inhibited cell growth and tube formation of HUVECs. Although the potent proangiogenic protein vascular endothelial growth factor (VEGF) stimulat...
