Structural Analysis of Mitochondria in Cardiomyocytes: Insights into Bioenergetics and Membrane Remodeling

open access: yesCurrent Issues in Molecular Biology, 2023
Mitochondria in mammalian cardiomyocytes display considerable structural heterogeneity, the significance of which is not currently understood. We use electron microscopic tomography to analyze a dataset of 68 mitochondrial subvolumes to look for ...

Assembly and Dynamics of Myofibrils [PDF]

open access: yesJournal of Biomedicine and Biotechnology, 2010
We review some of the problems in determining how myofibrils may be assembled and just as importantly how this contractile structure may be renewed by sarcomeric proteins moving between the sarcomere and the cytoplasm. We also address in this personal review the recent evidence that indicates that the assembly and dynamics of myofibrils are conserved ...

Lbx2regulates formation of myofibrils [PDF]

open access: yesBMC Developmental Biology, 2009
Skeletal muscle differentiation requires assembly of contractile proteins into organized myofibrils. The Drosophila ladybird homeobox gene (lad) functions in founder cells of the segmental border muscle to promote myoblast fusion and muscle shaping. Tetrapods have two homologous genes (Lbx).

A Supramolecular Polymerization Approach to the Growth of the Myofibril

open access: yesFrontiers in Chemistry, 2019
Extended linear structures self-assemble by the multi-stage-open-association mechanism of supramolecular polymerization (MSOA). Application of the model requires the identification of a repeating unit, the main-chain supramolecular bond, and the binding ...

A Novel Method of Isolating Myofibrils From Primary Cardiomyocyte Culture Suitable for Myofibril Mechanical Study

open access: yesFrontiers in Cardiovascular Medicine, 2019
Myofibril based mechanical studies allow evaluation of sarcomeric protein function. We describe a novel method of obtaining myofibrils from primary cardiomyocyte culture.

Mechanobiology of muscle and myofibril morphogenesis

open access: yesCells & Development, 2021
Muscles generate forces for animal locomotion. The contractile apparatus of muscles is the sarcomere, a highly regular array of large actin and myosin filaments linked by gigantic titin springs. During muscle development many sarcomeres assemble in series into long periodic myofibrils that mechanically connect the attached skeleton elements.

Sarcomere formation occurs by the assembly of multiple latent protein complexes. [PDF]

open access: yesPLoS Genetics, 2010
The stereotyped striation of myofibrils is a conserved feature of muscle organization that is critical to its function. Although most components that constitute the basic myofibrils are well-characterized biochemically and are conserved across the animal

Effects of high-pressure treatment on the structure and function of myofibrils

open access: yesBiophysics and Physicobiology, 2021
The effects of high pressure (40–70 MPa) on the structure and function of myofibrils were investigated by high pressure microscopy. When this pressure was applied to myofibrils immersed in relaxing solution, the sarcomere length remained almost unchanged,

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.
