Mechanisms of vascular smooth muscle contraction and the basis for pharmacologic treatment of smooth muscle disorders [PDF]

, 2016
The smooth muscle cell directly drives the contraction of the vascular wall and hence regulates the size of the blood vessel lumen. We review here the current understanding of the molecular mechanisms by which agonists, therapeutics, and diseases ...

Cardiac Myosin Activation for the Treatment of Systolic Heart Failure.

Journal of Cardiovascular Pharmacology, 2020
Left ventricular systolic dysfunction is the hallmark pathology in heart failure with reduced ejection fraction. Increasing left ventricular contractility with beta-adrenergic receptor agonists, phosphodiesterase-3 inhibitors, or levosimendan has failed ...

Force stimulation promotes nerve regeneration by restoring cellular energy

BMEMat, EarlyView.
Mechanical stimulation can help nerves regenerate in various ways. We developed two devices (a piezo‐motor‐driven stretching device and a SAW‐based actuator) to apply mechanical stimulation to sciatic nerve and DRG neurons. Our study shows that appropriate mechanical force stimulation can promote regeneration by restoring the energy supply to the ...

Targeting myocardial equilibrative nucleoside transporter ENT1 provides cardioprotection by enhancing myeloid Adora2b signaling

JCI Insight, 2023
Previous studies implicate extracellular adenosine signaling in attenuating myocardial ischemia and reperfusion injury (IRI). This extracellular adenosine signaling is terminated by its uptake into cells by equilibrative nucleoside transporters (ENTs ...

Gene expression analyses implicate an alternative splicing program in regulating contractile gene expression and serum response factor activity in mice. [PDF]

PLoS ONE, 2013
Members of the CUG-BP, Elav-like family (CELF) regulate alternative splicing in the heart. In MHC-CELFΔ transgenic mice, CELF splicing activity is inhibited postnatally in heart muscle via expression of a nuclear dominant negative CELF protein under an α-

Age- and activity-related differences in the abundance of Myosin essential and regulatory light chains in human muscle [PDF]

, 2016
Traditional methods for phenotyping skeletal muscle (e.g., immunohistochemistry) are labor-intensive and ill-suited to multixplex analysis, i.e., assays must be performed in a series. Addressing these concerns represents a largely unmet research need but

Mechanisms of a novel regulatory light chain–dependent cardiac myosin inhibitor

Journal of General Physiology
Hypertrophic cardiomyopathy (HCM) is a genetic disease of the heart characterized by thickening of the left ventricle (LV), hypercontractility, and impaired relaxation. HCM is caused primarily by heritable mutations in sarcomeric proteins, such as β myosin heavy chain.

Titin Is Present in the Elastic Tethers That Connect Separating Anaphase Chromosomes in Crane‐Fly Spermatocytes

Cytoskeleton, EarlyView.
ABSTRACT Elastic tethers connect telomeres of separating chromosomes in anaphase of animal cells. Immunofluorescence staining of titin in crane‐fly spermatocytes, using 4 different antibodies, shows that the giant elastic protein titin seems to be a component of mitotic tethers: titin “strands” extend between separating chromosomes, connecting their ...

Proteasome inhibition slightly improves cardiac function in mice with hypertrophic cardiomyopathy

Frontiers in Physiology, 2014
A growing line of evidence indicates dysfunctional ubiquitin-proteasome system (UPS) in cardiac diseases. Anti-hypertrophic effects and improved cardiac function have been reported after treatment with proteasome inhibitors in experimental models of ...

Cell-based gene therapy for mending infarcted hearts [PDF]

, 2011
The goal of this study was to analyse the efficiency of a combinatorial cell/growth factor therapy to improve function of infarcted murine hearts. The Insulin-like Growth Factor-1 (IGF-1) isoform, IGF-1Ea, has been shown to reduce scar formation and ...
