Effect of Resistance Exercise and Vitamin C Intake on Expression of Telomerase Reverse Transcriptase and Telomere Repeat Binding Factor-2 Genes and the Diameter and Number of Myofibrils in Old Rats

open access: yesComplementary Medicine Journal of Faculty of Nursing and Midwifery, 2021
Objective: Cell aging is one of the most important and fundamental step in cellular behavior and reduces muscle mass and myofibrils. This study aims to investigate the effect of resistance exercise along with vitamin C consumption on the expression of ...

Bimolecular Fluorescence Complementation (BiFC) for Studying Sarcomeric Protein Interactions in Drosophila

open access: yesBio-Protocol, 2020
Protein-protein interactions in Drosophila myofibrils are essential for their function and formation. Bimolecular Fluorescence Complementation (BiFC) is an effective method for studying protein interactions and localization.

Mechanical and kinetic effects of shortened tropomyosin reconstituted into myofibrils [PDF]

open access: yes, 2009
The effects of tropomyosin on muscle mechanics and kinetics were examined in skeletal myofibrils using a novel method to remove tropomyosin (Tm) and troponin (Tn) and then replace these proteins with altered versions.

The effect of recombinant caspase 3 on myofibrillar proteins in porcine skeletal muscle

open access: yesAnimal, 2008
The objective of this study was to investigate the potential role of the caspase protease family in meat tenderisation by examining if caspase 3 was capable of causing myofibril protein degradation.

Lipid composition of heart muscle homogenate

open access: yesJournal of Lipid Research, 1965
Using cytochrome oxidase and esterase assays as a guide, mitochondria and microsomes were prepared from ox heart homogenate with about 25% cross-contamination of phospholipid.

Cooperation between myofibril growth and costamere maturation in human cardiomyocytes

open access: yesFrontiers in Bioengineering and Biotechnology, 2022
Costameres, as striated muscle-specific cell adhesions, anchor both M-lines and Z-lines of the sarcomeres to the extracellular matrix. Previous studies have demonstrated that costameres intimately participate in the initial assembly of myofibrils ...

Role of Myofibrillar Protein Catabolism in Development of Glucocorticoid Myopathy: Aging and Functional Activity Aspects

open access: yesMetabolites, 2016
Muscle weakness in corticosteroid myopathy is mainly the result of the destruction and atrophy of the myofibrillar compartment of fast-twitch muscle fibers.

Mechanical characterization of skeletal muscle myofibrils

open access: yes, 1996
A new instrument, based on a technique described previously, is presented for studying mechanics of micron-scale preparations of two to three myofibrils or single myofibrils from muscle. Forces in the nanonewton to micronewton range are measurable with 0.

Tension-driven multi-scale self-organisation in human iPSC-derived muscle fibers

open access: yeseLife, 2022
Human muscle is a hierarchically organised tissue with its contractile cells called myofibers packed into large myofiber bundles. Each myofiber contains periodic myofibrils built by hundreds of contractile sarcomeres that generate large mechanical forces.
