Higher levels of nonprotein amino acid homocysteine (Hcy), that is, hyperhomocysteinemia (HHcy) (~5% of general population) has been associated with severe vasculopathies in different organs; however, precise molecular mechanism(s) as to how HHcy plays havoc with body's vascular networks are largely unknown. Interventional modalities have not proven beneficial to counter multifactorial HHcy's effects on the vascular system. An ancient Indian form of exercise called 'yoga' causes transient ischemia as a result of various body postures however the cellular mechanisms are not clear...

Aim: Tafazzin knockdown (TazKD) in mice is widely used to create an experimental model of Barth syndrome (BTHS) that exhibits dilated cardiomyopathy and impaired exercise capacity. Peroxisome proliferator-activated receptors (PPARs) are a group of nuclear receptor proteins that play essential roles as transcription factors in the regulation of carbohydrate, lipid, and protein metabolism. We hypothesized that the activation of PPAR signaling with PPAR agonist bezafibrate (BF) may ameliorate impaired cardiac and skeletal muscle function in TazKD mice...

BACKGROUND: Evidence of the efficacy of high-intensity, low-volume interval training (HIIT-low volume) in treating insulin resistance (IR) in patients with metabolic disorders is contradictory. In addition, it is unknown whether this effect is mediated through muscle endocrine function, which in turn depends on muscle mass and fiber type composition. Our aims were to assess the efficacy of HIIT-low volume compared to continuous aerobic exercise (CAE) in treating IR in adults with metabolic syndrome (MS) and to establish whether musclin, apelin, muscle mass and muscle composition are mediators of the effect...

Musclin is a bioactive factor that functions in regulating the muscle growth and metabolism. To investigate the transcriptional regulatory mechanism of the gene, the 1.4 kb musclin promoter in sheep was cloned (GenBank accession: JX966391) and the sequence was analyzed to predict the motifs associated with muscle growth. Next the enhanced green fluorescent protein (EGFP) was selected as the reporter gene and various wild-type and motif-mutant vectors were constructed. The transcriptional regulatory activities were compared by observing the fluorescence strength and detecting the EGFP mRNA expression in C2C12 myoblasts transfected with the vectors...

BACKGROUND: Musclin is a novel skeletal muscle-derived secretory factor considered to be a potent regulator of the glucose metabolism and therefore may contribute to the pathogenesis of obesity and insulin resistance (IR). METHODS: To test this hypothesis, we examined the plasma musclin levels in overweight/obese subjects and lean controls. Rats on a high fat diet (HFD) were used as the annimal model of obesity. Radioimmunoassay and western blot were used to determine musclin levels in plasma and skeletal muscle...

The natriuretic peptide (NP) system is a critical endocrine, autocrine, and paracrine system and has been investigated for potential use against cardiovascular and metabolic diseases. The clearance of NPs is regulated by the proteolysis of neutral endopeptidase (NEP) and by endocytosis via natriuretic peptide receptor-3 (NPR3). A linear NPR3-selective peptide, [Cha8 ]-ANP(7-16)-NH2 (1), showed potent binding affinity for NPR3 but poor predicted chemical stability due to its free thiol group. A 12-mer peptide (9) without a thiol group was designed by the hybridization of two NPR3-binding peptides: a linear ANP fragment peptide analog and musclin, a murine member of the bHLH family of transcription factors, possessed high binding affinity and strict selectivity for NPR3...

BACKGROUND: Musclin is a newly identified skeletal muscle-derived secretory factor, which has been recently characterized as a stimulator that induces insulin resistance in mice. However, the pathophysiological role of musclin in humans remains poorly understood. The aim of this study was to explore the potential correlations between musclin plasma levels and various metabolic parameters in patients with type 2 diabetes mellitus. MATERIALS AND METHODS: In this hospital-based study, plasma samples were collected from the enrolled individuals, including 38 newly diagnosed, treatment-naive type 2 diabetes mellitus patients and 41 age- and gender-matched control subjects...

Sensory experience evokes long-lasting changes in neural circuits through activity-dependent gene expression. Ataman et al. (2016) report in Nature that primates evolved novel transcriptional responses to neuronal activity, including induction of musclin/osteocrin (OSTN), which may regulate specialized aspects of primate neural circuits.

What is more interesting about brown adipose tissue (BAT) is its ability to provide thermogenesis, protection against obesity by clearing triglycerides, releasing batokines, and mitigating insulin resistance. White adipose tissue (WAT) on the other hand stores excess energy and secretes some endocrine factors like leptin for regulating satiety. For the last decade there has been an increasing interest in the browning of fat keeping in view its beneficial effects on metabolic disorders and protection in the form of perivascular fat...

This study aimed to evaluate the effects of exercise training on triglyceride deposition and the expression of musclin and glucose transporter 4 (GLUT4) in a rat model of insulin resistance. Thirty male Sprague-Dawley rats (8 weeks old, weight 160±10 g) were fed a high-fat diet (40% calories from fat) and randomly divided into high-fat control group and swimming intervention group. Rats fed with standard food served as normal control. We found that 8-week swimming intervention significantly decreased body weight (from 516...

Sarcolemmal ATP-sensitive potassium (KATP) channels control skeletal muscle energy use through their ability to adjust membrane excitability and related cell functions in accordance with cellular metabolic status. Mice with disrupted skeletal muscle KATP channels exhibit reduced adipocyte size and increased fatty acid release into the circulation. As yet, the molecular mechanisms underlying this link between skeletal muscle KATP channel function and adipose mobilization have not been established. Here, we demonstrate that skeletal muscle-specific disruption of KATP channel function in transgenic (TG) mice promotes production and secretion of musclin...

Exercise remains the most effective way to promote physical and metabolic wellbeing, but molecular mechanisms underlying exercise tolerance and its plasticity are only partially understood. In this study we identify musclin-a peptide with high homology to natriuretic peptides (NP)-as an exercise-responsive myokine that acts to enhance exercise capacity in mice. We use human primary myoblast culture and in vivo murine models to establish that the activity-related production of musclin is driven by Ca(2+)-dependent activation of Akt1 and the release of musclin-encoding gene (Ostn) transcription from forkhead box O1 transcription factor inhibition...

Musclin is a type of muscle-secreted cytokine and its increased gene expression induces insulin resistance in type 2 diabetes. However, the mechanism underlying increased musclin gene expression is currently unclear. Excessive saturated fatty acids (SFA) can activate the secretion of several muscle-secreted cytokines as well as endoplasmic reticulum (ER) stress pathway, thereby contributing to the development of type 2 diabetes. The purpose of this study was to investigate the mechanisms responsible for the effect of palmitate, the most abundant SFA in the plasma, on the gene expression of musclin in C2C12 myotubes...

Musclin is a novel skeletal muscle-derived factor found in the signal sequence trap of mouse skeletal muscle cDNAs. Recently, it has been demonstrated that musclin is involved in the pathogenesis of spontaneously hypertensive rats (SHRs). However, it is known as a genetic hypertension model. In the present study, we aim to investigate the role of musclin in another animal model of hypertension and characterize the direct effect of musclin on vascular contraction. The results show that expression of musclin was increased in arterial tissues isolated from DOCA-salt induced hypertensive rats or the normal rats received repeated vasoconstriction with phenylephrine...

Musclin is a novel skeletal muscle-derived secretory factor found in the signal sequence trap of mouse skeletal muscle cDNAs. Musclin possesses a region homologous to the natriuretic peptide family. Thus, musclin is found to bind with the natriuretic peptide clearance receptors. However, the role of musclin in vascular regulation remains unclear. In this study, we aim to investigate the direct effect of musclin on vascular tone and to analyze its role in hypertension using the spontaneously hypertensive rats (SHR)...

Menopause, the age-related loss of ovarian hormone production, promotes increased adiposity and associated metabolic pathology, but molecular mechanisms remain unclear. We previously reported that estrogen increases skeletal muscle PPARdelta expression in vivo, and transgenic mice overexpressing muscle-specific PPARdelta are reportedly protected from diet-induced obesity. We thus hypothesized that obesity observed in ovariectomized mice, a model of menopause, may result in part from abrogated expression of muscle PPARdelta and/or downstream mediators such as FoxO1...

Musclin is a novel skeletal muscle-derived secretory factor that was isolated by our group. Musclin contains a region homologous to natriuretic peptides (NPs). This study investigated the interaction between musclin and NP receptors (NPRs). Musclin specifically bound to NPR3, but not to NPR1 or NPR2. Musclin and atrial natriuretic peptide (ANP) competed for binding to NPR3. We conducted binding assays using various synthetic musclin peptides and mutant musclin proteins. The first NP-homologous region in musclin ((88)LDRL(91)) and the second homologous region ((117)MDRI(120)) were responsible cooperatively for high-affinity binding to NPR3...

Musclin is a muscle-derived secretory peptide that induces insulin resistance in vitro. We studied the effect of musclin (0.5 microg/ml) on insulin-stimulated glucose uptake in rat skeletal muscles and also the effect of rosiglitazone (0.4 microg/ml). Preincubation of muscles with musclin resulted in decreased insulin-stimulated glucose uptake. Musclin also reduced expression of peroxisome proliferator-activated receptor gamma (PPARgamma) and liver X receptor alpha (LXRalpha) mRNAs, although expression of glucose transporter 4 mRNA was unaltered...
