The role of L-type Ca(2+) channels (LTCCs) and RhoA/Rho kinase (ROCK) on depolarization-induced sustained arterial contraction lasting several minutes is already known. However, in vivo, vascular smooth muscle cells can be depolarized for longer periods, inducing substantial inactivation of LTCCs and markedly reducing Ca(2+) influx into the myocytes. We have examined, in femoral arterial rings, the role of LTCCs and RhoA/ROCK during long-lasting depolarization. Our results reveal a new vasoreactive response after 20-30min of depolarization in 2...

Abnormal uterine bleeding (AUB) is a common complication of anticoagulant therapy in premenopausal women affected with acute venous thromboembolism. AUB impacts quality of life, and can lead to premature cessation of anticoagulation. There is increasing data to suggest that the direct oral anticoagulants when used for the treatment of venous thromboembolism differ in their menstrual bleeding profile. This article aims to review the existing literature regarding the association between AUB and the direct oral anticoagulants and make practical recommendations...

BACKGROUND: Vitamin D deficiency represents a major health problem in general population, especially for its association with cardiovascular disorders and thrombotic risk, even in patients on dual antiplatelet therapy (DAPT). Vitamin D Binding Protein (VDBP) is the main transporter of vitamin D in the bloodstream and genetic polymorphisms of this protein have been shown to account for a significant variability of vitamin D levels and its systemic effects. Contrasting data have linked the rs7041 T→G substitution with cardiovascular disease...

The implications of altered coagulation-fibrinolytic system in the pathophysiology of several vascular disorders, such as stroke and myocardial infarction, have been well researched upon and established. However, its role in the progression of diabetic retinopathy has not been explored much. Since a decade, it is known that hyperglycemia is associated with a hypercoagulated state and the various impairments it causes are well acknowledged as independent risk factors for the development of cardiovascular diseases...

Angiopoietin-1 (Ang-1) is a ligand of Tie-2 receptors that promotes survival, migration, and differentiation of endothelial cells. Several studies have linked reactive oxygen species (ROS) to Ang-1 signaling and distinct angiogenic responses, but the molecular sources of these ROS have never been clearly identified. In this study, we have identified source-specific contributions of ROS to Ang-1/Tie 2 signaling and angiogenic responses in human umbilical vein endothelial cells (HUVECs), specifically the differential contributions of mitochondrial ROS (mtROS) and ROS from two isoforms of NADPH oxidase (NOX2, NOX4)...

BACKGROUND: Dipeptidyl peptidase-4 (DPP-4) inhibitors have various cellular effects that are associated with vascular protection. Here, we examined whether teneligliptin alters the pro-inflammatory phenotype of perivascular adipose tissue (PVAT) and inhibits atherogenesis. METHODS AND RESULTS: Teneligliptin (60mg/kg/day) was administered orally to apolipoprotein-E-deficient (ApoE(-/-)) mice for 20weeks. Teneligliptin significantly inhibited the development of atherosclerosis in the aortic arch compared with vehicle (P<0...

Beyond its function in hemostasis, platelets activation has an important role in cardiovascular diseases (CVD) development. There are different clinical conditions that can mediate abnormal platelet activation and favors pathological thrombosis and CVD. These include Hypertension, diabetes and dyslipidemia, all risks factors from CVD development. Different drugs employed in the handled of these conditions have showed decreases platelet activation and related markers. This effect is in part by improved the base condition; however someone of these drugs can modulate platelet targets...

OBJECTIVE: The balance between nitric oxide (NO)-sensitive and -insensitive forms of soluble guanylate cyclase (sGC) has been demonstrated to be disrupted in certain lifestyle-related diseases. However, it remains unclear whether type 2 diabetes results in a shift of sGC to the NO-insensitive form. This study addressed this issue in the human blood vessel. METHODS: Internal thoracic arteries were obtained from patients undergoing coronary artery bypass grafting...

Residual cardiovascular (CV) risk remains in some patients despite optimized statin therapy and may necessitate add-on therapy to reduce this risk. Eicosapentaenoic acid (EPA), an omega-3 polyunsaturated fatty acid, lowers plasma triglyceride levels without raising low-density lipoprotein cholesterol levels and has potential beneficial effects on atherosclerotic plaques. Animal studies have shown that EPA reduces levels of pro-inflammatory cytokines and chemokines. In clinical trials utilizing a wide spectrum of plaque imaging modalities, EPA has shown beneficial effects on plaque characteristics...

AIM: The neuropeptide calcitonin gene-related peptide (CGRP) is found in afferent sensory nerve fibers innervating the resistance arteries and plays a pivotal role in a number of neurovascular diseases such as migraine and subarachnoid bleedings. The present study investigates the binding and antagonistic characteristics of small non-peptide CGRP receptor antagonists (i.e. gepants) in isolated rat brain and mesenteric resistance arteries. METHODS: The antagonistic behavior of gepants was investigated in isolated rat mesenteric arteries using a wire myograph setup while binding of gepants to CGRP receptors was investigated in rat brain membranes using a radioligand competitive binding assay...

AIMS: Levosimendan is an inodilator for the treatment of acute decompensated heart failure (HF). Data from clinical studies suggest that levosimendan is particularly effective in HF due to myocardial infarction. After acute revascularization, no reflow-phenomenon is a common complication that may lead to pump failure and cardiogenic shock. Our aim was to examine whether levosimendan interferes with the pro-thrombotic phenotype of activated endothelial cells in vitro. METHODS: Human heart microvascular endothelial cells (HHMEC) and human umbilical vein endothelial cells (HUVEC) were treated with interleukin-1β (IL-1β) (200U/mL) or thrombin (5U/mL) and co-treated with or without levosimendan (0...

Diabetic microangiopathy, including retinopathy, is characterized by abnormal growth and leakage of small blood vessels, resulting in local edema and functional impairment of the depending tissues. Mechanisms leading to the impairment of microcirculation in diabetes are multiple and still largely unclear. However, a dysregulated vascular regeneration appears to play a key role. In addition, oxidative and hyperosmolar stress, as well as the activation of inflammatory pathways triggered by advanced glycation end-products and toll-like receptors, have been recognized as key underlying events...

Current anti-angiogenic therapies in malignant and ocular diseases target growth factor signaling in order to attenuate excessive vascular growth. Although initial responses are promising, overall therapeutic success is limited due to insufficient efficiency, tumor refractoriness and resistance. Emerging evidence suggests that diverse growth factor signaling pathways in endothelial cells (ECs) converge onto cellular metabolism, creating an attractive target for novel alternative anti-angiogenic therapies. Recent studies show that ECs rely on glycolysis for ATP and biomass synthesis, necessary for proliferation and migration, key processes of angiogenesis...

Reactive oxygen species (ROS) as well as vascular endothelial growth factor (VEGF) play important roles in pathologic retinal neovascularization. We investigated whether betaine inhibits pathologic retinal neovascularization in a mouse model of oxygen induced retinopathy (OIR). Betaine was intravitreally injected in OIR mice at postnatal day (P) 14. At P17, the neovascular tufts area in OIR retina was analyzed. Intravitreal injection of betaine (200μM) effectively reduced the neovascular tufts area in OIR retina (68...

Camptothecin (CPT) has been used for colorectal cancer therapy. At low concentration of 10(-9)M, CPT modulates endothelial nitric oxide production following the phosphorylation of LKB1 Ser431, AMPK-α Thr172, eNOS Ser633 and Ser1177. Elevated nitric oxide (NO) was observed by FA-OMe fluorescent probe. 726 S-nitrosoproteins were identified by iTRAQ quantitative proteomics. IPA analysis indicated that ERK/MAPK was closely linked in the signaling network. Further studies showed that CPT phosphorylated p38 MAPK Thr180/Tyr182 and dephosphorylated Tau Ser199/202...

Perioperative hyperglycemia is a common clinical metabolic disorder. Hyperglycemia could induce endothelial apoptosis, dysfunction and inflammation, resulting in endothelial injury. Propofol is a widely used anesthetic drug in clinical settings. Our previous studies indicated that propofol, via inhibiting high glucose-induced PP2A expression, attenuated high glucose-induced reactive oxygen species (ROS) accumulation, thus improving endothelial apoptosis, dysfunction and inflammation. However, the mechanisms by which propofol attenuated high glucose-induced PP2A expression is still obscure...

Angiogenesis is important in cancer progression and can be influenced by tumor-associated myofibroblasts. We addressed the hypothesis that glucocorticoids indirectly affect angiogenesis by altering the release of pro-angiogenic factors from colon cancer-derived myofibroblasts. Our study shows that glucocorticoids reduced prostanoids, urokinase-type plasminogen activator (uPA) and angiopoietin-like protein-2 (ANGPTL2) levels, but increased angiogenin (ANG) in supernatant from human CT5.3hTERT colon cancer-derived myofibroblasts...

The prevention of cancer development and its progression is an urgent unmet medical need. Novel knowledge on the biology of cancer has evidenced that genetic changes occurring within cancer cells contribute, but are not sufficient, for tumor promotion and progression. The results of clinical studies and experimental animal models have suggested pursuing new avenues for the prevention of cancer development in the early stages, by using drugs that modulate platelet responses and those interfering with the synthesis and action of the mediators of inflammation...
