Displaced Myonuclei in Cancer Cachexia Suggest Altered Innervation [PDF]

open access: yesInternational Journal of Molecular Sciences, 2020
An idiopathic myopathy characterized by central nuclei in muscle fibers, a hallmark of muscle regeneration, has been observed in cancer patients. In cancer cachexia skeletal muscle is incapable of regeneration, consequently, this observation remains unaccounted for.

Skeletal Muscle Activity and the Fate of Myonuclei [PDF]

open access: yesActa Naturae, 2010
Adult skeletal muscle fiber is a symplast multinuclear structure developed in ontogenesis by the fusion of the myoblasts (muscle progenitor cells). The nuclei of a muscle fiber (myonuclei) are those located at the periphery of fiber in the space between myofibrils and sarcolemma.

A Touch from Myofibroblasts Puts the Squeeze on Myonuclei [PDF]

open access: yesDevelopmental Cell, 2018
The even positioning of nuclei at the periphery of differentiated myofibers is among the most striking examples of cellular organization. In this issue of Developmental Cell, Roman et al. (2018) show that fibronectin deposited by the associated myofibroblasts initiates both lateral and peripheral nuclear movements by distinct downstream mechanisms.

Effects of mutant lamins on nucleo-cytoskeletal coupling in Drosophila models of LMNA muscular dystrophy

open access: yesFrontiers in Cell and Developmental Biology, 2022
The nuclei of multinucleated skeletal muscles experience substantial external force during development and muscle contraction. Protection from such forces is partly provided by lamins, intermediate filaments that form a scaffold lining the inner nuclear ...

Nucleus Type-Specific DNA Methylomics Reveals Epigenetic “Memory” of Prior Adaptation in Skeletal Muscle

open access: yesFunction, 2021
Using a mouse model of conditional and inducible in vivo fluorescent myonuclear labeling (HSA-GFP), sorting purification of nuclei, low-input reduced representation bisulfite sequencing (RRBS), and a translatable and reversible model of exercise ...

Myonuclei acquired by overload exercise precede hypertrophy and are not lost on detraining [PDF]

open access: yesProceedings of the National Academy of Sciences, 2010
Effects of previous strength training can be long-lived, even after prolonged subsequent inactivity, and retraining is facilitated by a previous training episode. Traditionally, such “muscle memory” has been attributed to neural factors in the absence of any identified local memory mechanism in the muscle tissue. We have used in vivo imaging techniques

Magnetic Resonance Microscopy (MRM) of Single Mammalian Myofibers and Myonuclei [PDF]

open access: yesScientific Reports, 2017
AbstractRecently, the first magnetic resonance microscopy (MRM) images at the cellular level in isolated mammalian brain tissues were obtained using microsurface coils. These methods can elucidate the cellular origins of MR signals and describe how these signals change over the course of disease progression and therapy.

Decoding the transcriptome of denervated muscle at single‐nucleus resolution

open access: yesJournal of Cachexia, Sarcopenia and Muscle, 2022
Background Skeletal muscle exhibits remarkable plasticity under both physiological and pathological conditions. One major manifestation of this plasticity is muscle atrophy that is an adaptive response to catabolic stimuli.

High intensity training may reverse the fiber type specific decline in myogenic stem cells in multiple sclerosis patients

open access: yesFrontiers in Physiology, 2016
Multiple sclerosis (MS) is associated with loss of skeletal muscle mass and function. The myogenic stem cells (satellite cells – SCs) are instrumental to accretion of myonuclei, but remain to be investigated in MS.
