Silent information regulator family protein 1 (Sirt1) has gained attention for protective effects against cardiovasc diseases. Vascular smooth muscle endothelin type B (ETB ) receptors are related to the pathogenesis of cardiovascular diseases. Elevated oxidized low-density lipoprotein (ox-LDL) is associated with atherosclerosis. This study will investgate whether resveratrol (a Sirt1 activator, Res) is involved in oxidized low density lipoprotein (ox-LDL)-mediated- regulation of ETB receptors in rat superior mesenteric arteries (SMA)...

Vascular dysfunction and insulin resistance (IR) are associated with obstructive sleep apnea (OSA), which is characterized by frequent episodes of nocturnal intermittent hypoxia (IH). While it is recognized that the balance between vasoconstrictive (endothelin-1) and vasodilatory molecules (nitric oxide, NO) determine vascular profile, molecular mechanisms contributing to vascular dysfunction and IR in OSA are not completely understood. Caveolin-1 is a membrane protein which regulates endothelial nitric oxide synthase (eNOS) activity which is responsible for NO generation and cellular insulin-signaling...

Vascular endothelial dysfunction and platelet activation play a key role in tumor metastasis, and therefore both of these processes are considered important therapeutic targets in cancer. The aim of our studies was to analyze anti-metastatic activity of combination therapy using nitric oxide donor DETA/NO and antiplatelet drug clopidogrel. Nitric oxide acts as a vasoprotective mediator, while clopidogrel inhibits ADP-mediated platelet aggregation. 4T1-luc2-tdTomato cell line transplanted intravenously (i.v...

BACKGROUND: Increasing epidemiological studies have confirmed the association between maternal preeclampsia and elevated blood pressure in their offspring. Though case-control or cohort studies have demonstrated long-term outcomes for the offspring of preeclampsia, it is still a question that how these changes were caused by genetic reasons or by preeclampsia itself. OBJECTIVE: In our study, we explored the potential epigenetic regulation of delta-like homolog 1-maternally expressed gene 3 (DLK1-MEG3) region in human umbilical vein endothelial cells (HUVECs), and its connection with endothelium-derived factors...

Chymase, a mast cell serine protease involved in the generation of multiple cardiovascular factors, such as angiotensin II and endothelin-1 (ET-1), is elevated and participates in tissue degeneration after permanent myocardial infarction (PMI). Anesthetized 4-month old male wild-type (WT) C57BL/6J mice and mouse mast cell protease-4 knockout (mMCP-4 KO) congeners were subjected to ligation of the left anterior descending (LAD) coronary artery. A group of mice was then subjected to Kaplan-Meier 28-day survival analysis...

Endothelin-1 (ET-1), a potent vasoconstrictor, is involved in retinal vascular dysregulation and oxidative stress in glaucomatous eyes. Taurine (TAU), a naturally occurring free amino acid, is known for its neuroprotective and antioxidant properties. Hence, we evaluated its neuroprotective properties against ET-1 induced retinal and optic nerve damage. ET-1 was administered intravitreally to Sprague-Dawley rats and TAU was injected as pre-, co- or post-treatment. Animals were euthanized seven days post TAU injection...

OBJECTIVES: The only curative treatment for chronic thromboembolic pulmonary hypertension (CTEPH) is pulmonary endarterectomy (PEA). PEA requires cardiopulmonary bypass (CPB) which is associated with a high acute kidney injury (AKI) risk. Circulating endothelin-1 (ET-1) levels are elevated in CTEPH, and ET-1 plays a pivotal role in AKI. Because AKI is burdened by high morbidity and mortality, we aimed to evaluate the association between preoperative ET-1 and the risk to develop AKI in CTEPH individuals who undergo PEA...

Lipopolysaccaride (LPS) directly or indirectly injures brain microvascular endothelial cells (BMECs) and damages the intercellular tight junction that gives rise to altered blood-brain barrier (BBB) permeability. Catalpol plays a protective role in LPS-induced injury, but whether catalpol protects against LPS-caused damage of BBB permeability and the underlying mechanism remain to be delineated. Prophylactic protection with catalpol (5 mg/kg, i.v.) consecutively for three days reversed the LPS-induced damage of BBB by decreased Evans Blue (EB) leakage and restored tight junctions in C57 mice...

Fishes of the genus Danio exhibit diverse pigment patterns that serve as useful models for understanding the genes and cell behaviors underlying the evolution of adult form. Among these species, zebrafish D. rerio exhibit several dark stripes of melanophores with sparse iridophores that alternate with light interstripes of dense iridophores and xanthophores. By contrast, the closely related species D. nigrofasciatus has an attenuated pattern with fewer melanophores, stripes and interstripes. Here we demonstrate species differences in iridophore development that presage the fully formed patterns...

Barbara Hausott, Lars Klimaschewski
Clinical trials applying growth factors to alleviate symptoms of patients with neurological disorders have largely been unsuccessful in the past. As an alternative approach, growth factor receptors or components of their signal transduction machinery may be targeted directly. In recent years, the search for intracellular signaling integrator downstream of receptor tyrosine kinases provided valuable novel substrates. Among them are the Sprouty proteins which mainly act as inhibitors of growth factor-dependent neuronal and glial signaling pathways...

BACKGROUND: Pulmonary hypertension complicating left heart disease (PH-LHD) is the most common cause of PH. Off-label use of pulmonary arterial hypertension (PAH) medications for PH-LHD is prevalent, despite a lack of clinical data supporting their use. METHODS: A systematic review and meta-analysis was performed. Comprehensive search of all available literature to date identified ten randomised, placebo controlled trials comprising 439 treated (Phosphodiesterase 5 inhibitors: n = 206; guanylate cyclase stimulators: n = 132; endothelin receptor antagonists: n = 101) and 338 placebo patients...

We have a large body of evidence showing that hyperglycemia is a cardiovascular risk factor and that its reduction decreases the risk for cardiovascular events. Indeed, epidemiological studies have clearly shown that hyperglycemia is a strong and independent factor for cardiovascular disease. In addition, we have many pathophysiological studies demonstrating the direct role of hyperglycemia in the development of atherosclerosis. Hyperglycemia, by stimulating protein kinase C, increases the production of pro-inflammatory cytokines, of adhesion molecules and of endothelin-1 and, by stimulating the polyol pathway, promotes the oxidative stress...

Diseases of the cardiovascular system are the leading cause of morbidity and mortality in men and women in developed countries, and CVD is becoming more prevalent in developing countries. Atherosclerotic cardiovascular disease (CVD) prevalence in men is greater than in women until menopause, when the prevalence of CVD increases in women until it exceeds that of men. Endothelial function is a barometer of vascular health and a predictor of atherosclerosis that may provide insights into sex differences in CVD, as well as how and why CVD risk drastically changes with menopause...

Renal ischemia-reperfusion (IR) injury and acute kidney injury (AKI) increase the risk of developing hypertension, with T cells suspected as a possible mechanistic link. Endothelin promotes renal T cell infiltration in several diseases, predominantly via the ETA receptor, but its contribution to renal T cell infiltration following renal IR injury is poorly understood. To test whether ETA receptor activation promotes T cell infiltration of the kidney following IR injury, male C57BL/6 mice were treated with the ETA receptor antagonist ABT-627 or vehicle, commencing 2 days prior to unilateral renal IR injury...
