BACKGROUND: Recent studies highlighted the protective benefits of a Chinese herb extract from polygonum cuspidatum, trans-polydatin, on cardiac disease. We investigated the therapeutic effect of trans-polydatin on myocardial ischemia/reperfusion (IR) injury and the underlying mechanisms related to the renin-angiotensin system (RAS) and RhoA kinase (ROCK) pathway. METHODS AND RESULTS: Experiments were performed on neonatal rats' ventricular myocytes that were subjected to hypoxia-reoxygenation (simulated IR, SIR) and on adult mice which were subjected to left anterior descending coronary artery occlusion for 45 min followed by a one-week reperfusion...

Qishenkeli (QSKL) is one of the Chinese medicine formulae for treating heart failure and has been shown to have an antifibrotic effect. However, the mechanism of its therapeutic effects remains unclear. In this study, we aimed to explore whether QSKL could exert an antifibrotic effect by attenuating ras homolog family member A (RhoA) and mitogen activated protein kinase (MAPK) pathways. Rats were randomly divided into sham group, model group, QSKL group, and positive control group. Heart failure was induced by ligation of the left ventricle anterior descending artery...

Cyclosporine (CSA) and nonsteroidal antiinflammatory drugs (NSAIDs) are used together to manage arthritic disorders with an immune component. Previous reports showed contrasting effects for NSAIDs on CSA nephrotoxicity and acute elevations in blood pressure. Both effects were ameliorated or exaggerated after selective cyclooxygenase-2 (COX2) and nonselective COX inhibition, respectively. Here we investigated: (i) the interaction of CSA with NSAIDs possessing variable COX1/COX2 selectivities on hemodynamic, left ventricular (LV) and cardiac autonomic and histologic profiles, and (ii) role of NADPH-oxidase (NOX)/Rho-kinase (ROCK) pathway in the interaction...

AIM: RhoA/Rho-associated kinase and arginase are implicated in vascular complications in diabetes. This study investigated whether RhoA/Rho-associated kinase and arginase inhibition protect from myocardial ischaemia-reperfusion injury in type 1 diabetes and the mechanisms behind these effects. METHODS: Rats with streptozotocin-induced type 1 diabetes and non-diabetic rats were subjected to 30 min myocardial ischaemia and 2 h reperfusion after being randomized to treatment with (1) saline, (2) RhoA/Rho-associated kinase inhibitor hydroxyfasudil, (3) nitric oxide synthase inhibitor N(G)-monomethyl-l-arginine monoacetate followed by hydroxyfasudil, (4) arginase inhibitor N-omega-hydroxy-nor-l-arginine, (5) N(G)-monomethyl-l-arginine monoacetate followed by N-omega-hydroxy-nor-l-arginine or (6) N(G)-monomethyl-l-arginine monoacetate given intravenous before ischaemia...

Currently, two or more pulmonary vasodilators are used to treat pulmonary arterial hypertension (PAH), but conventional vasodilators alone cannot reverse disease progression. In this study, we tested the hypothesis that a combination therapy comprising a vasodilator plus a therapeutic agent that slows pulmonary arterial remodeling and right heart hypertrophy is an efficacious alternative to current vasodilator-based PAH therapy. Thus, we encapsulated a cocktail of superoxide dismutase (SOD), a superoxide scavenger, and fasudil, a specific rho-kinase inhibitor, into a liposomal formulation equipped with a homing peptide, CAR...

Gestational diabetes mellitus is a risk factor for congenital heart defects; however, the molecular basis of the congenital heart anomalies remains obscure. Previous reports showed a positive correlation between abnormal cardiomyocyte apoptosis and ventricular wall thinness, one type of congenital heart anomaly. This work explored the expression pattern and molecular mechanism of the Rho-associated coiled-coil containing protein kinase 1 (ROCK1) gene in cardiomyocyte apoptosis and genesis of ventricular wall thinness...

Type IV collagen, a nonfibrillar type, is ubiquitously expressed in the basement membrane around cardiomyocytes. Canstatin, a cleaved product of α2 chain of type IV collagen, is an antiangiogenic factor. Because it has not been clarified whether canstatin exerts other biological activities in heart, we investigated the effects of canstatin on adult rat cardiac fibroblasts. Cell migration was determined by Boyden chamber assay. Western blotting was performed to detect secretion of matrix metalloproteinase-2 (MMP-2) and MMP-9 and phosphorylation of extracellular signal-regulated kinase (ERK)...

OBJECTIVE: To investigate the changes of autophagy in ischemic myocardium of rats treated with fasudil for inhibiting Rho kinase. METHODS: The hearts isolated from male Sprague-Dawley rats were subjected to 30 min of occlusion of the left anterior descending artery followed by 120 min of reperfusion with or without treatment with fasudil or fasudil+Wort. The left ventricular hemodynamics were continuously recorded, and the coronary effluent was collected during the reperfusion to determine lactate dehydrogenase (LDH) levels...

BACKGROUND: Cardiac metabolism is critical for the functioning of the heart, and disturbance in this homeostasis is likely to influence cardiac disorders or cardiomyopathy. Our laboratory has previously shown that SNRK (sucrose nonfermenting related kinase) enzyme, which belongs to the AMPK (adenosine monophosphate-activated kinase) family, was essential for cardiac metabolism in mammals. Snrk global homozygous knockout (KO) mice die at postnatal day 0, and conditional deletion of Snrk in cardiomyocytes (Snrk cmcKO) leads to cardiac failure and death by 8 to 10 months...

OBJECTIVE: Comparing BP response to Ca channel opener BAY K8644 prior and after Rho kinase inhibition we demonstrated lowered calcium sensitization in spontaneously hypertensive rats (SHR), although BP response of intact SHR to Rho kinase inhibitor fasudil was enhanced (Behuliak et al. J Hypertens 31:2025,2013). The aim of the present study was to evaluate calcium sensitization in hypertensive TGR and their normotensive HanSD controls using the same methods. We also tried to elucidate the interference of baroreflex-activated sympathetic activity with BP response to fasudil...

Elevated sympathetic tone and activation of the renin-angiotensin system are pathophysiologic hallmarks of hypertension, and the interactions between these systems are particularly deleterious. The importance of Rho kinase as a mediator of the effects of angiotensin-II (AngII) in the periphery is clear, but the role of Rho kinase in sympathoexcitation caused by central AngII is not well established. We hypothesized that AngII mediates its effects in the brain by the activation of the RhoA/Rho kinase pathway...

Liraglutide, a glucagon-like peptide-1 receptor (GLP-1R) agonist, is widely used to treat diabetes. However, its effect on pulmonary arterial hypertension (PAH) is unknown. In this study, we investigated its effects on rats with monocrotaline (MCT)-induced PAH and mechanisms on rat pulmonary artery smooth muscle cells (PASMCs). Liraglutide was investigated for both prevention and treatment of MCT-induced PAH. The hemodynamic and body weight changes, right heart hypertrophy, lung morphology, immune-reactivity of endothelial nitric oxide synthase (eNOS), endothelin-1 and cyclic guanosine monophosphate (cGMP) levels, protein expressions of eNOS, soluble guanylyl cyclase (sGCα), protein kinase G (PKG) and Rho kinase (ROCK) II pathway were measured in both in vivo and in vitro...

Previous study showed inhibition of RhoA and Rho kinase (ROCK) activity with fasudil could alleviate diabetes-induced cardiac dysfunction partially due to improvement of myocardial fibrosis. However, the effect of fasudil on intracellular calcium cycling and actin remodeling, both of which are important to regulate excitation-contract coupling, is still not fully elucidated. In this study, a diabetic cardiomyopathy model was induced by a single intraperitoneal injection of streptozotocin (STZ) in male Sprague Dawley rats...

Myocardial infarction (MI) and hypertension are the leading cause of death worldwide so protection of heart is focus of intense research. Rho-kinase, a downstream effector of protein involved in MI and hypertension, is inhibited by ibuprofen. This study aims to elucidate cardioprotective effect of ibuprofen in rats. MI was produced in rats with 85mg/kg isoproterenol (ISO) administered s.c. twice at an interval of 24h. The rats were randomized into six groups: (I) Normal; (II) ISO; (III) ISO + ascorbic acid (250mg/kg p...

The fetal cardiovascular responses to acute hypoxia includes a redistribution of the cardiac output towards the heart and the brain at the expense of other organs, such as the intestine. We hypothesized that hypoxia exerts a direct effect on the mesenteric artery (MA) that may contribute to this response. Using wire myography, we investigated the response to hypoxia (Po2 ~2.5 kPa for 20 min) of isolated MAs from 15- to 21-d chicken embryos (E15, E19 E21), and 1- to 45-d-old chickens (P1, P3, P14, P45). Agonist-induced pretone or an intact endothelium were not required to obtain a consistent and reproducible response to hypoxia, which showed a pattern of initial rapid phasic contraction followed by a sustained tonic contraction...

Protein kinase D (PKD) consists of a family of three structurally related enzymes that are co-expressed in the heart and have important roles in many biological responses. PKD1 is activated by pro-hypertrophic stimuli and has been implicated in adverse cardiac remodeling. Efforts to define the cardiac actions of PKD2 and PKD3 have been less successful at least in part because conventional methods provide a general screen for PKD activation but are poorly suited to resolve activation patterns for PKD2 or PKD3...

BACKGROUND: Pulmonary hypertension due to left heart disease (PH-LHD) is one of the most common forms of PH, termed group 2 PH. Atorvastatin exerts beneficial effects on the structural remodeling of the lung in ischemic heart failure. However, few studies have investigated the effects of atorvastatin on PH due to left heart failure induced by overload. METHODS: Group 2 PH was induced in animals by aortic banding. Rats (n = 20) were randomly divided into four groups: a control group (C), an aortic banding group (AOB63), an atorvastatin prevention group (AOB63/ATOR63) and an atorvastatin reversal group (AOB63/ATOR50-63)...
