Pig cardiac myosin isoenzymes.

European journal of cell biology, 1980
Pig heart myosins isolated from the free wall of the right ventricle and the free wall of the left ventricle were compared with respect to structural and enzymatic properties. The following parameters were studied (1) activation of myosin ATase by Ca2+ and K+j(2) molecular weight of the heavy and light chains of myosins as determined by electrophoretic

Force transmission in epithelial tissues [PDF]

, 2016
In epithelial tissues, cells constantly generate and transmit forces between each other. Forces generated by the actomyosin cytoskeleton regulate tissue shape and structure and also provide signals that influence cells' decisions to divide, die, or ...

Considerations for drug trials in hypertrophic cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1095-1112, April 2025.
Abstract Hypertrophic cardiomyopathy (HCM) is a heterogeneous condition with potentially serious manifestations. Management has traditionally comprised therapies to palliate symptoms and implantable cardioverter‐defibrillators to prevent sudden cardiac death. The need for disease‐modifying therapies has been recognized for decades.

A highly soluble, non-phototoxic, non-fluorescent blebbistatin derivative [PDF]

, 2016
Blebbistatin is a commonly used molecular tool for the specific inhibition of various myosin II isoforms both in vitro and in vivo. Despite its popularity, the use of blebbistatin is hindered by its poor water-solubility (below 10 micromolar in aqueous ...

Semaglutide normalizes increased cardiomyocyte calcium transients in a rat model of high fat diet‐induced obesity

ESC Heart Failure, Volume 12, Issue 2, Page 1386-1397, April 2025.
Sequeira et al. reveal how the glucagon‐like peptide‐1 receptor agonist (GLP‐1‐RA) semaglutide restores cardiomyocyte function in rats subjected to a high‐fat/high‐fructose diet (HFD). Employing fluorescence‐ and patch‐clamp technology in isolated cardiac myocytes, they demonstrate that semaglutide reverses HFD‐induced activation of L‐type calcium ...

Protein multi-scale organization through graph partitioning and robustness analysis: Application to the myosin-myosin light chain interaction

, 2011
Despite the recognized importance of the multi-scale spatio-temporal organization of proteins, most computational tools can only access a limited spectrum of time and spatial scales, thereby ignoring the effects on protein behavior of the intricate ...

Experiment K-6-10. Effects of zero gravity on myofibril protein content and isomyosin distribution in rodent skeletal muscle [PDF]

The purpose of this experiment was to investigate the effects of 12 days of zero gravity (0G) exposure (Cosmos 1887 Biosputnik) on the enzymatic properties, protein content, and isomyosin distribution of the myofibril fraction of the slow-twitch vastus ...

Recovering actives in multi-antitarget and target design of analogs of the myosin II inhibitor blebbistatin [PDF]

, 2018
In multitarget drug design, it is critical to identify active and inactive compounds against a variety of targets and antitargets. Multitarget strategies thus test the limits of available technology, be that in screening large databases of compounds vs a

Mapping the Global Clinical Landscape of Pharmacological Therapies for Heart Failure With Preserved Ejection Fraction: An Analysis Based on ClinicalTrials.gov (2003–2025)

iMetaMed, EarlyView.
This study analyzed 236 heart failure with preserved ejection fraction (HFpEF) pharmacological trials registered on ClinicalTrials.gov from 2003 to 2025, revealing a post‐2016 surge (76.3%), U.S. dominance (58.5%), and prominence of SGLT2 inhibitors/novel therapies (each 13.1%).

Functional and biophysical analyses of the class XIV Toxoplasma gondii Myosin D [PDF]

, 2018
Summary: The obligate intracellular parasite Toxoplasma gondii uses gliding motility to migrate across the biological barriers of the host and to invade cells. This unique form of locomotion requires an intact actin cytoskeleton and involves at least one
