Angiotensin II induces expression of the Tie2 receptor ligand, angiopoietin-2, in bovine retinal endothelial cells.
|
7 |
11289054
|
In this study, we investigated the effect of angiotensin II (AII) on Ang1 and Ang2 expression in cultured bovine retinal endothelial cells (BRECs).
|
8 |
11289054
|
AII stimulated Ang2 but not Ang1 mRNA expression in a dose- and time-dependent manner.
|
9 |
11289054
|
Protein kinase C (PKC) inhibitor completely inhibited AII-induced Ang2 expression, and the mitogen-activated protein kinase (MAPK) inhibitor also inhibited it by 69.4+/-15.6%.
|
10 |
11289054
|
These data suggest that AII stimulates Ang2 expression through AT1 receptor-mediated PKC and MAPK pathways in BREC, and AII may play a novel role in retinal neovascularization.

Expressional regulation of angiopoietin-1 and -2 and the tie-1 and -2 receptor tyrosine kinases during cutaneous wound healing: a comparative study of normal and impaired repair.
|
12 |
11310829
|
As angiogenesis is central to a normal wound-healing process, we investigated the regulation of Ang-1 and -2 and the related tyrosine kinase with immunoglobulin and epidermal growth factor homology (Tie)-1 and -2 receptors during normal repair in Balb/c mice and diabetes-impaired wound healing conditions in genetically diabetic (db/db) mice.
|
13 |
11310829
|
For both normal and impaired healing conditions, we observed a constitutive expression of Ang-1, which was paralleled by an increase of Ang-2 upon injury.
|
14 |
11310829
|
Furthermore, Tie-1 was strongly induced during repair with a prolonged expression in diabetic mice, whereas Tie-2 expression was constitutive during normal repair but completely absent in diabetes-impaired healing.
|
15 |
11310829
|
The overexpression of Ang-2 in the presence of markedly reduced VEGF in wounds of diabetic mice was associated with a dramatic decrease in endothelial cell numbers compared with normal healing as assessed by analysis of the endothelium-specific markers CD31 and von Willebrand factor, whereas the lymphatic endothelium remained stable as determined by expression of VEGF receptor-3 (VEGFR-3/Flt-4).

To establish a model of continuous endothelial activation and to elucidate the role of endothelial derived TNF in vivo, we generated transgenic mice expressing a noncleavable transmembrane form of TNF under the control of the endothelial-specific tie2 promoter.
|
22 |
11564813
|
Adult tie2-transmembrane TNF-transgenic mice developed chronic inflammatory pathology in kidney and liver, characterized by perivascular infiltration of mononuclear cells into these organs.

Along with the infiltrate, an up-regulation of the adhesion molecules ICAM-1 and VCAM-1, but not E-selectin, in the endothelium was observed.
|
24 |
11564813
|
Although the blood levels of soluble TNF and IFN-gamma were increased in transgenic animals after challenge with Con A, no damage of hepatocytes could be detected, as assessed by the lack of increase in plasma transaminase activities and the absence of TUNEL staining in the liver.

Because pericyte recruitment and endothelial cell survival are controlled, in part, by the angiopoietin/Tie2 ligand/receptor system, we studied the expression of angiopoietin-2 and -1 in relation to the evolution of pericyte loss in diabetic rat retinae, using quantitative retinal morphometry, and in retinae from mice with heterozygous angiopoietin deficiency (Ang-2 LacZ knock-in mice).

Members of the vascular endothelial growth factor (VEGF) family are key stimulators that interact with two tyrosine kinase receptors, VEGF receptor (VEGFR)1 and 2; binding to two other receptors that lack tyrosine kinase activity, the neuropilins, is also important.

|
Furthermore, SHP-1 bond to Tie-2 receptor and stimulation with Ang-1 led to SHP-1 dissociation from Tie-2 in mouse heart microvascular endothelial cell (MHMEC).
|

|
Exposure of MHMEC to high glucose (HG, 30 mmol/L) increased SHP-1/Tie-2 association accompanied by a significant reduction of Tie-2 phosphorylation.
|
131 |
22454630
|
Exposure of MHMEC to HG also blunted Ang-1-mediated SHP-1/Tie-2 dissociation.
|
132 |
22454630
|
Knockdown of SHP-1 significantly attenuated HG-induced caspase-3 activation and apoptosis in MHMEC.
|
133 |

|
Treatment with PTP inhibitors restored Ang-1-induced Akt/eNOS phosphorylation and angiogenesis.
|
134 |
22454630
|
Our data implicate a critical role of SHP-1 in diabetes-associated vascular complications, and that upregulation of Ang-1/Tie-2 signaling by targeting SHP-1 should be considered as a new therapeutic strategy for the treatment of diabetes-associated impairment of angiogenesis.

We recently demonstrated that reducing IGF-1 receptor (IGF-1R) numbers in the endothelium enhances nitric oxide (NO) bioavailability and endothelial cell insulin sensitivity.
|
176 |
22733797
|
To examine the effect of increasing IGF-1R in the endothelium, we generated mice overexpressing human IGF-1R in the endothelium (human IGF-1R endothelium-overexpressing mice [hIGFREO]) under direction of the Tie2 promoter enhancer. hIGFREO aorta had reduced basal NO bioavailability (percent constriction to N(G)-monomethyl-l-arginine [mean (SEM) wild type 106% (30%); hIGFREO 48% (10%)]; P < 0.05).

Apelin receptor (APLNR) and the endogenous ligand of APLNR, apelin, induce the sprouting of endothelial cells in an autocrine or paracrine manner, which may be one of the mechanisms of DN.
|
179 |

|
Therefore, we observed apelin/APLNR expression in kidneys from patients with type 2 diabetes as well as the correlation between albuminuria and serum apelin in patients with type 2 diabetes.
|
180 |
23577111
|
The results showed that serum apelin was significantly higher in the patients with type 2 diabetes compared to healthy people (p<0.05, Fig. 1B) and that urinary albumin was positively correlated with serum apelin (R = 0.78, p<0.05).
|
181 |
23577111
|
Apelin also promoted the permeability of glomerular endothelial cells (p<0.05) and upregulated the expression of VEGFR2 and Tie2 in glomerular endothelial cells (p<0.05).
|
182 |
23577111
|
These results indicated that upregulated apelin in type 2 diabetes, which may be attributed to increased fat mass, promotes angiogenesis in glomeruli to form abnormal vessels and that enhanced apelin increases permeability via upregulating the expression of VEGFR2 and Tie2 in glomerular endothelial cells.
