Structural dynamics of myosin 5 during processive motion revealed by interferometric scattering microscopy

eLife, 2015
Myosin 5a is a dual-headed molecular motor that transports cargo along actin filaments. By following the motion of individual heads with interferometric scattering microscopy at nm spatial and ms temporal precision we found that the detached head ...

Atrophy, oxidative switching and ultrastructural defects in skeletal muscle of the ataxia telangiectasia mouse model [PDF]

, 2019
Ataxia telangiectasia is a rare, multi system disease caused by ATM kinase deficiency. Atm-knockout mice recapitulate premature aging, immunodeficiency, cancer predisposition, growth retardation and motor defects, but not cerebellar neurodegeneration and

Fibrillar Bundles as Fibrous Filler Materials for Attaining Cell Anisotropy in Bioprinting

Advanced Healthcare Materials, EarlyView.
Fibrillar bundles are introduced as a bioprintable additive that enables robust and scalable cellular alignment within 3D constructs through flow‐induced orientation during extrusion. These fibers support strong cell adhesion and polarization across various cell types and significantly enhance myotube alignment in Gelatine‐Methacryloyl (GelMA ...

Myosin [PDF]

The Journal of General Physiology, 1967
There is fairly general agreement that myosin isolated from rabbit skeletal muscle has a molecular weight of about 500,000. The higher values that have been reported apparently reflect protein aggregation related to the method of preparation. On the basis of present evidence, the myosin molecule has an elongate helical core of two f subunits (average ...

Myosin-I nomenclature. [PDF]

, 2001
We suggest that the vertebrate myosin-I field adopt a common nomenclature system based on the names adopted by the Human Genome Organization (HUGO). At present, the myosin-I nomenclature is very confusing; not only are several systems in use, but several

Giving It a Twist: One‐Step Fabrication of Aligned Biomimetic Yarn Scaffolds via Rotational Melt Electrofibrillation

Advanced Healthcare Materials, EarlyView.
Due to its multifunctionality, replicating the fibrillar and supramolecular architecture of Collagen I is gaining increasing priority in regenerative medicine. Using rotational Melt Electrofibrillation, we present a powerful method to accurately mimic the ultrastructure of Collagen with polycaprolactone, enabling the one‐step fabrication of three ...

Molecular mechanisms of the regulation of ATPase cycle in striated muscle [PDF]

, 2007
New data on the molecular mechanism of the regulation of ATPase cycle by troponin-tropomyosin system have been obtained in reconstructed muscle fibers by using the polarized fluorescence technique, which allowed us following the azimuthal movements of ...

Tailored Xenogeneic‐Free Polymer Surface Promotes Dynamic Migration of Intestinal Stem Cells

Advanced Materials, EarlyView.
This study introduces a PoLymer‐coated Ultra‐stable Surface (PLUS), a nitrogen plasma‐treated poly(ethyleneglycoldimethacrylate), as a stable xenogeneic‐free platform for intestinal stem cell culture. PLUS enhances cell attachment, supports actin‐driven migration, and retains functionality after 3 years of storage. Promoting cytoskeletal reorganization,

Architecture of an All‐In‐One Microfluidic Platform for Accelerated Cancer Seeding, Enhanced Spheroid Formation, and Dynamic Drug Screening Trials

Advanced Materials Technologies, EarlyView.
An all‐in‐one microfluidic platform consists of two‐layered PDMS channels integrated with a hydrogel microwell array. This platform enables flow‐driven tumor cell capture, enhanced spheroid formation within the microwells, and advective drug testing. ABSTRACT Effective cancer drug screening requires platforms that replicate the physiological complexity

Effect of the Partial Substitution of NaCl with L-Arg on the Gel Properties and Aggregation Behavior of Beef Myosin

Foods
With 0.3 M KCl replacing NaCl, the effect of L-Arg on beef myosin’s gel, structure, and aggregation was investigated. L-Arg could enhance hydrogen and ionic bonds, increasing myosin solubility and reducing turbidity.
