Context: Hypertension in young women is uncommon compared to young men and older women. Estrogen appears to protect most women against hypertension with incidence increasing after menopause. Since some premenopausal women develop hypertension, estrogen may play a different role in these women. Genetic variations in the estrogen receptor (ER) are associated with cardiovascular disease. ER-β, encoded by ESR2, is the ER predominantly expressed in vascular smooth muscle. Objective: To determine an association of single nucleotide polymorphisms (SNPs) in ESR2 with salt-sensitivity of blood pressure (SSBP) and estrogen status in women...

BACKGROUND: Muscle weakness is a risk factor for mortality in hemodialysis (HD) patients. Muscle strength measurements are routinely used as a screening tool but depend on patient cooperation and motivation. We wished to determine whether measuring maximal voluntary muscle strength was affected by patient self-reported distress. METHODS: We measured pinch strength (PS) and handgrip strength (HGS) in 382 adult HD patients with a corresponding self-reported distress thermometer (DT) scores...

Atherosclerosis is a chronic inflammatory disease characterized by the accumulation of lipids, smooth muscle cell proliferation, cell apoptosis, necrosis, fibrosis, and local inflammation. Immune and inflammatory responses have significant effects on every phase of atherosclerosis, and increasing evidence shows that immunity plays a more important role in atherosclerosis by tightly regulating its progression. Therefore, understanding the relationship between immune responses and the atherosclerotic microenvironment is extremely important...

Biologically active epoxyeicosatrienoic acid (EET) regioisomers are synthesized from arachidonic acid by cytochrome P450 epoxygenases of endothelial, myocardial, and renal tubular cells. EETs relax vascular smooth muscle and decrease inflammatory cell adhesion and cytokine release. Renal EETs promote sodium excretion and vasodilation to decrease hypertension. Cardiac EETs reduce infarct size after ischemia-reperfusion injury and decrease fibrosis and inflammation in heart failure. In diabetes, EETs improve insulin sensitivity, increase glucose tolerance, and reduce the renal injury...

Activation of calmodulin dependent protein kinase (CaMK)II by exercise is beneficial in controlling membrane lipids associated with type 2 diabetes and obesity. Regulation of lipid metabolism is crucial in the improvement of type 2 diabetes and obesity associated symptoms. The role of CaMKII in membrane associated lipid metabolism was the focus of this study. Five to six weeks old male Wistar rats were used in this study. GC×GC-TOFMS technique was used to determine the levels of polyunsaturated fatty acids (linoleic acid, arachidonic acid and 11,14-eicosadienoic acid)...

Neurotrophins are present in the gastrointestinal tract where they participate in the survival and growth of enteric neurons, augmentation of enteric circuits, elevation of colonic myoelectrical activity and also in different aspects of colitis. Previous studies largely focused on the role of neural and mucosal neurotrophins in gut inflammation. The expression of neurotrophins in colonic smooth muscle cells (SMCs) and the interactions of this potential source with colitis has not been studied in the gut. The expression of NGF, BDNF, NT-3 and TN-4 in SMCs from longitudinal and circular muscle layers of rat colon from normal and Dextran sodium sulphate (DSS)-induced colitis rats was measured by ELISA...

Nitric oxide (NO) is an important endogenous neurotransmitter and mediator. It participates in regulation of physiological processes in different organ systems including airways. Therefore, it is important to clarify its role in the regulation of both airway and vascular smooth muscle, neurotransmission and neurotoxicity, mucus transport, lung development and in the. surfactant production. The bioactivity of NO is highly variable and depends on many factors: the presence and activity of NO-producing enzymes, activity of competitive enzymes (e...

BACKGROUND: Congenital myasthenic syndromes (CMSs) are a group of clinically and genetically heterogeneous disorders caused by impaired neuromuscular transmission. The defect of AGRN was one of the causes of CMS through influencing the development and maintenance of neuromuscular transmission. However, CMS reports about this gene mutation were rare. Here, we report a novel homozygous missense mutation (c.5302G>C) of AGRN in a Chinese CMS pedigree. METHODS: We performed a detailed clinical assessment of a Chinese family with three affected members...

Amyotrophic lateral sclerosis (ALS) is a disabling progressive disease characterized by the degeneration of motor neurons, leading to muscle atrophy and paralysis. The majority of cases are sporadic, but also a familiar form of ALS exists, and some genes causative of the pathology were found. In particular, mutations in superoxide dismutase 1 (SOD1) were found in 20% of familiar cases. It is known that neuroinflammation plays a pivotal role in several neurodegenerative disorders, including ALS. Inflammasomes are protein complexes that induce inflammation in response to various stimuli, involved also in neuroinflammation...

Mesenchymal stem cells (MSCs) are multipotent stem cells that reside in various organs. They have the capacity to differentiate into various cell types, including cardiomyocytes, vascular endothelial cells, and vascular smooth muscle cells. Among the various MSCs, bone marrow-derived MSCs (BMMSCs) have been widely used for treating acute myocardial infarction (AMI) and ischemic heart failure (IHF) in preclinical and clinical studies. Although the beneficial effects of BMMSCs in treating AMI and IHF were originally attributed to their capacity to differentiate into cardiac cell types, recent evidence suggests that the differentiation capacity of BMMSCs appears to be minimal and that BMMSCs exert cardioprotective effects by secreting paracrine factors...

Extracellular vesicles are now widely recognized as key players in the prevention, repair or progression of cardiovascular disease. Here we first focus on the functional roles of extracellular vesicles in the cross-talk between cardiomyocytes and endothelial cells, important for maintaining normal development and function of the heart. Second, we discuss the role of extracellular vesicles secreted by embryonic and non-embryonic stem cells in repairing cardiomyocyte function and in restoring angiogenic potential after myocardial ischemia-reperfusion injury...

OBJECTIVE: The prognosis of bladder cancer patients with positive lymph node (LN) disease is affected by both the extent of lymphadenectomy and LN density retrieved during radical cystectomy. This study aimed at assessing the differences in LN metastasis between patients who presented primarily with muscle-invasive transitional cell carcinoma of the bladder "de novo disease" versus "progressive disease." The latter is defined as patients who progressed to muscle-invasive bladder cancer (MIBC) following prior conservative management of a non-muscle-invasive disease...

The impact of broad-spectrum antibiotics on antimicrobial resistance and disruption of the beneficial microbiome compels the urgent investigation of bacteria-specific approaches such as antibody-based strategies. Among these, DNA-delivered monoclonal antibodies (DMAbs), produced by muscle cells in vivo, potentially allow the prevention or treatment of bacterial infections circumventing some of the hurdles of protein IgG delivery. Here, we optimize DNA-delivered monoclonal antibodies consisting of two potent human IgG clones, including a non-natural bispecific IgG1 candidate, targeting Pseudomonas aeruginosa...

Some of the Chronic Obstructive Pulmonary Disease (COPD) patients engaged in exercise-based muscle rehabilitation programs are unresponsive. To unravel the respective role of chronic hypoxia and pulmonary inflammation on soleus muscle hypertrophic capacities, we challenged male Wistar rats to repeated lipopolysaccharide instillations, associated or not with a chronic hypoxia exposure. Muscle hypertrophy was initiated by bilateral ablation of soleus agonists 1 week before sacrifice. To understand the role played by the histone acetylation, we also treated our animals with an inhibitor of bromodomains and extra terminal proteins (I-BET) during the week after surgery...

Cocoa polyphenols are thought to reduce the risk of cardiovascular diseases. Thus, cocoa-containing foods may have significant health benefits. Here, we studied the impact of chocolate liquor on vascular lesion development and plaque composition in a mouse model of atherosclerosis. Apolipoprotein E (apoE)-knockout mice were assigned to two groups and fed a Western diet that contained 250 g/kg of either chocolate liquor or a polyphenol-free isoenergetic control paste for 16 weeks. In addition to fat, protein and fibers, the chocolate liquor contained 2 g/kg of polyphenols...

Nuclear factor-erythroid 2-related factor-2 (Nrf2) is a master regulator of the anti-oxidant response. However, studies in models of Friedreich's ataxia (FA), a neuro- and cardio-degenerative disease associated with oxidative stress, reported decreased Nrf2 expression due to unknown mechanisms. Using a mouse conditional frataxin knockout (KO) model in the heart and skeletal muscle, we examined the Nrf2 pathway in these tissues. Frataxin KO results in fatal cardiomyopathy, while skeletal muscle was asymptomatic...

Peripheral artery disease (PAD) is a morbid condition whereby ischemic peripheral muscle causes pain and tissue breakdown. Interestingly, PAD risk factors, e.g. diabetes mellitus, cause endothelial dysfunction secondary to decreased nitric oxide (NO) levels, which could explain treatment failures. Previously, we demonstrated 670nm light (R/NIR) increased NO from nitrosyl-heme stores, therefore we hypothesized R/NIR can stimulate vasodilation in healthy and diabetic blood vessels. Vasodilation was tested by ex vivo pressure myography in wild type C57Bl/6, endothelial nitric oxide synthase (eNOS) knockout, and db/db mice (10mW/cm(2) for 5min with 10min dark period)...
