New Drug Shows Promise against Muscle Wasting Disease
A new drug to treat the muscle wasting disease inclusion body myositis (IBM) reverses key symptoms in mice and is safe and well-tolerated in patients. Researchers found that the new drug Arimoclomol reversed the disease’s effects at the cellular level and improved muscle strength in mice.

Small Molecule-Mediated Up-Regulation of MicroRNA Targeting a Key Cell Death Modulator BNIP3 Improves Cardiac Function following Ischemic Injury
Investigators report that a small molecule inducer of microRNA-182 suppressed ischemia/reperfusion-induced cardiac cell death by down-regulating BCL2/adenovirus E1B 19 kDa protein-interacting protein 3 (BNIP3). [Sci Rep] Full Article

Tetrahydrobiopterin Protects against Hypertrophic Heart Disease Independent of Myocardial Nitric Oxide Synthase Coupling
Genetically augmenting tetrahydrobiopterin (BH4) synthesis in endothelial cells fails to replicate this benefit, indicating that other cell types dominate the effects of exogenous BH4 administration. Researchers tested whether the primary cellular target of BH4 is the cardiomyocyte or whether other novel mechanisms are invoked. [J Am Heart Assoc] Abstract

Effects of Short-Chain Acyl-CoA Dehydrogenase on Cardiomyocyte Apoptosis
Investigators determined the role of short-chain acyl-CoA dehydrogenase (SCAD) in tert-butyl hydroperoxide-induced cardiomyocyte apoptosis. The mRNA and protein expression of SCAD were significantly down-regulated in the cardiomyocyte apoptosis model. [J Cell Mol Med] Full Article


UTX Demethylase Activity Is Required for Satellite Cell–Mediated Muscle Regeneration
Researchers employed an inducible mouse KO that specifically ablates Utx in satellite cells and demonstrated that active H3K27 demethylation is necessary for muscle regeneration. [J Clin Invest] Full Article

Pax3+ Skeletal Muscle Satellite Cells Retain Long-Term Self-Renewal and Proliferation
Investigators used cell-surface markers and paired box transcription factor 3 (Pax3)/Pax7 expression to separate satellite cells populations. In addition, self-renewal, proliferation, and differentiation abilities of each population were analyzed. [Muscle Nerve] Abstract


Salusin-β Induces Foam Cell Formation and Monocyte Adhesion in Human Vascular Smooth Muscle Cells via miR155/NOX2/NFκB Pathway
Scientists showed that salusin-β increased foam cell formation evidenced by accumulation of lipid droplets and intracellular cholesterol content, and promoted monocyte adhesion in human vascular smooth muscle cells. [Sci Rep] Full Article

Transient Contractions of Urinary Bladder Smooth Muscle Are Drivers of Afferent Nerve Activity during Filling
Using an ex vivo mouse bladder preparation, investigators explored the relative contributions of filling pressure and transient contraction-induced pressure transients to sensory nerve stimulation. [J Gen Physiol]

Caveolae Are Involved in Mechanotransduction during Pulmonary Hypertension
Researchers investigated how caveolae are involved in the pathophysiology of pulmonary hypertension (PH) and particularly in mechanotransduction. Pulmonary arterial smooth muscle cells were freshly isolated from control rats and rats suffering from PH induced by three weeks of chronic hypoxia. [Am J Physiol Lung Cell Mol Physiol] Abstract

The Role of CD36 in the Regulation of Myocardial Lipid Metabolism
The authors review the role of CD36 in myocardial lipid metabolism in the healthy heart, and describe how CD36-mediated alterations in lipid metabolism may contribute to cardiovascular disease. [Biochim Biophys Acta] Abstract

Myocyte-Fibroblast Communication in Cardiac Fibrosis and Arrhythmias: Mechanisms and Model Systems
Investigators focus on mechanisms of myocyte-fibroblast communication and their effects on disease features such as cardiac fibrosis and arrhythmias as well as methods being used and currently developed in this field. [J Mol Cell Cardiol] Abstract

Regenerative Pharmacology for the Treatment of Acute Kidney Injury: Skeletal Muscle Stem/Progenitor Cells for Renal Regeneration?
The authors discuss the current development in acute kidney injury (AKI) treatment using different types of mesenchymal stem cells and the pilot results of the experimental study in vivo using a novel type of stem cells − skeletal muscle-derived stem/progenitor cells for the treatment of gentamicin-induced AKI.
