Biomechanical Properties of the Sarcolemma and Costameres of Skeletal Muscle Lacking Desmin

open access: yesFrontiers in Physiology, 2021
Intermediate filaments (IFs), composed primarily by desmin and keratins, link the myofibrils to each other, to intracellular organelles, and to the sarcolemma.

Distorting the sarcomere [PDF]

open access: yesJournal of General Physiology, 2010
One of the goals of cardiovascular science is to create a mathematical model of the heart that can predict ventricular function in healthy and diseased states, and that can be used to help improve treatment options for patients with heart disease. To be clinically useful, the model will have to include structural information about the shapes of the ...

Active Viscoelasticity of Sarcomeres [PDF]

open access: yesFrontiers in Robotics and AI, 2018
The perturbation response of muscle is important for the versatile, stable and agile control capabilities of animals. Muscle resists being stretched by developing forces in the passive tissues and in the active crossbridges. This review focuses on the active perturbation response of the sarcomere. The active response exhibits typical stress relaxation,

Volume overload impedes the maturation of sarcomeres and T-tubules in the right atria: a potential cause of atrial arrhythmia following delayed atrial septal defect closure

open access: yesFrontiers in Physiology, 2023
Introduction: Adult patients with atrial septal defects (ASD), the most common form of adult congenital heart disease, often die of arrhythmias, and the immaturity of cardiomyocytes contributes significantly to arrhythmias.

Actinin BioID reveals sarcomere crosstalk with oxidative metabolism through interactions with IGF2BP2

open access: yesCell Reports, 2021
Summary: Actinins are strain-sensing actin cross-linkers that are ubiquitously expressed and harbor mutations in human diseases. We utilize CRISPR, pluripotent stem cells, and BioID to study actinin interactomes in human cardiomyocytes.

Force enhancement after stretch of isolated myofibrils is increased by sarcomere length non-uniformities

open access: yesScientific Reports, 2020
When a muscle is stretched during a contraction, the resulting steady-state force is higher than the isometric force produced at a comparable sarcomere length.

Spontaneous sarcomere dynamics [PDF]

open access: yesChaos: An Interdisciplinary Journal of Nonlinear Science, 2010
Sarcomeres are the basic force generating units of striated muscles and consist of an interdigitating arrangement of actin and myosin filaments. While muscle contraction is usually triggered by neural signals, which eventually set myosin motors into motion, isolated sarcomeres can oscillate spontaneously between a contracted and a relaxed state.

Ablation of palladin in adult heart causes dilated cardiomyopathy associated with intercalated disc abnormalities

open access: yeseLife, 2023
Palladin (PALLD) belongs to the PALLD/myopalladin (MYPN)/myotilin family of actin-associated immunoglobulin-containing proteins in the sarcomeric Z-line.

Myomesin is part of an integrity pathway that responds to sarcomere damage and disease.

open access: yesPLoS ONE, 2019
The structure and function of the sarcomere of striated muscle is well studied but the steps of sarcomere assembly and maintenance remain under-characterized.

Muscle in Variable Gravity: “I Do Not Know Where I Am, But I Know What to Do”

open access: yesFrontiers in Physiology, 2021
Purpose: Fascicle and sarcomere lengths are important predictors of muscle mechanical performance. However, their regulation during stretch-shortening cycle (SSC) activities in usual and challenging conditions is poorly understood.
