A transcriptomics resource reveals a transcriptional transition during ordered sarcomere morphogenesis in flight muscle

open access: yeseLife, 2018
Muscles organise pseudo-crystalline arrays of actin, myosin and titin filaments to build force-producing sarcomeres. To study sarcomerogenesis, we have generated a transcriptomics resource of developing Drosophila flight muscles and identified 40 ...

Sarcomere lengths in wooden breast broiler chickens

open access: yesItalian Journal of Animal Science, 2020
The present study aims to measure the sarcomere lengths in normal broiler muscles and in non-lesion sites of breast muscles focally affected by Wooden Breast (WB).

Molecular-scale visualization of sarcomere contraction within native cardiomyocytes

open access: yesNature Communications, 2021
Sarcomeres, the building blocks of striated muscles, comprise ordered actomyosin arrays involved in force production. Here, the authors visualize sarcomere organization in neonatal cardiomyocytes with in situ cryo-electron tomography, revealing a reduced

Sarcomere mechanics in striated muscles: from molecules to sarcomeres to cells [PDF]

open access: yesAmerican Journal of Physiology-Cell Physiology, 2017
Muscle contraction is commonly associated with the cross-bridge and sliding filament theories, which have received strong support from experiments conducted over the years in different laboratories. However, there are studies that cannot be readily explained by the theories, showing 1) a plateau of the force-length relation extended beyond optimal ...

KLHL41 stabilizes skeletal muscle sarcomeres by nonproteolytic ubiquitination

open access: yeseLife, 2017
Maintenance of muscle function requires assembly of contractile proteins into highly organized sarcomeres. Mutations in Kelch-like protein 41 (KLHL41) cause nemaline myopathy, a fatal muscle disorder associated with sarcomere disarray.

The sarcomeric cytoskeleton: from molecules to motion [PDF]

open access: yesJournal of Experimental Biology, 2016
ABSTRACT Highly ordered organisation of striated muscle is the prerequisite for the fast and unidirectional development of force and motion during heart and skeletal muscle contraction. A group of proteins, summarised as the sarcomeric cytoskeleton, is essential for the ordered assembly of actin and myosin filaments into sarcomeres, by ...

Mitochondrial network configuration influences sarcomere and myosin filament structure in striated muscles

open access: yesNature Communications, 2022
How different physical configurations between sarcomeres and mitochondria alter energetic support for contractile function of skeletal muscle is not clear.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Chronological and Spatial Distribution of Skeletal Muscle Fat Replacement in FHL1‐Related Myopathies

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Variants in the FHL1 gene cause FHL1‐related myopathies (FHL1‐RMs), a group of neuromuscular disorders with diverse clinical presentations. This study aimed to comprehensively characterize the spatial and temporal patterns of skeletal muscle fat replacement throughout the whole body in FHL1‐RMs, to examine disease progression over ...

Biceps femoris long head sarcomere and fascicle length adaptations after 3 weeks of eccentric exercise training

open access: yesJournal of Sport and Health Science, 2022
Background: Eccentric exercise increases muscle fascicle lengths; however, the mechanisms behind this adaptation are still unknown. This study aimed to determine whether biceps femoris long head (BFlh) fascicle length increases in response to 3 weeks of ...
