Effects of Inhomogeneous Myofibril Morphology on Optical Diffraction in Single Muscle Fibers [PDF]

open access: yes, 2008
doi:10.1364/JOSAA.25.003051Laser diffraction is commonly used in physiological research that explores single muscle fibers. Although variations in sarcomere morphological properties have often been observed, their effects on laser diffraction have not ...

Actin, α-actinin, and tropomyosin interaction in the structural organization of actin filaments in nonmuscle cells [PDF]

open access: yes, 1975
During the spreading of a population of rat embryo cells, approximately 40% of the cells develop a strikingly regular network which precedes the formation of the straight actin filament bundles seen in the fully spread out cells.

Reductions in ATPase activity, actin sliding velocity, and myofibril stability yield muscle dysfunction in Drosophila models of myosin-based Freeman–Sheldon syndrome

open access: yesMolecular Biology of the Cell, 2019
Using Drosophila melanogaster, we created the first animal models for myosin-based Freeman–Sheldon syndrome (FSS), a dominant form of distal arthrogryposis defined by congenital facial and distal skeletal muscle contractures.

High-intensity interval training alleviates exhaustive exercise-induced HSP70-assisted selective autophagy in skeletal muscle

open access: yesJournal of Physiological Sciences, 2023
This study was designed to probe the effect of chaperone-assisted selective autophagy (CASA) on the maintenance of proteostasis during exhaustive exercise and uncover the alteration of CASA in muscle fibers with pre-high-intensity interval training (HIIT)

Magnetic susceptibility anisotropy of myocardium imaged by cardiovascular magnetic resonance reflects the anisotropy of myocardial filament α-helix polypeptide bonds. [PDF]

open access: yes, 2015
BackgroundA key component of evaluating myocardial tissue function is the assessment of myofiber organization and structure. Studies suggest that striated muscle fibers are magnetically anisotropic, which, if measurable in the heart, may provide a tool ...

Geometrically Tunable Scaffold‐Free Muscle Bioconstructs for Treating Volumetric Muscle Loss

open access: yesAdvanced Healthcare Materials, EarlyView.
Volumetric muscle loss is associated with traumatic muscle resulting in permanent functional impairment. Mold‐based, scaffold‐free, high‐density muscle tissue bioconstructs are developed in customizable geometric shapes and sizes. The transplanted rectangular solid‐shaped muscle bioconstructs improved muscle force recovery and tissue regeneration in ...

Kinetic mechanism of myofibril ATPase

open access: yesBiophysical Journal, 1994
The kinetic mechanism of myofibril ATPase was investigated using psoas and mixed back muscle over a range of ionic strengths. Myofibrils were labeled with pyrene iodoacetamide to measure the rate constants for the binding of ATP and formation of the weakly attached state.

DAAM is required for thin filament formation and Sarcomerogenesis during muscle development in Drosophila. [PDF]

open access: yes, 2012
During muscle development, myosin and actin containing filaments assemble into the highly organized sarcomeric structure critical for muscle function.

Novel functions for integrin-associated proteins revealed by analysis of myofibril attachment in Drosophila

open access: yeseLife, 2018
We use the myotendinous junction of Drosophila flight muscles to explore why many integrin associated proteins (IAPs) are needed and how their function is coordinated.
