Automated cross-sectional analysis of trained, severely atrophied, and recovering rat skeletal muscles using MyoVision 2.0

MR Viggars, Y Wen, CA Peterson… - Journal of Applied …, 2022 - journals.physiology.org
The number of myonuclei within a muscle fiber is an important factor in muscle growth, but its
regulation during muscle adaptation is not well understood. We aimed to elucidate the time …

Adaptation of the transcriptional response to resistance exercise over 4 weeks of daily training

MR Viggars, H Sutherland, H Lanmüller… - Faseb …, 2022 - researchonline.ljmu.ac.uk
We present the time course of change in the muscle transcriptome 1 h after the last exercise
bout of a daily resistance training program lasting 2, 10, 20, or 30 days. Daily exercise in rat …

Knockdown of the E3 ubiquitin ligase UBR5 and its role in skeletal muscle anabolism

…, LM Baehr, RA Seaborne, M Viggars… - … of Physiology-Cell …, 2021 - journals.physiology.org
UBR5 is an E3 ubiquitin ligase positively associated with anabolism, hypertrophy, and recovery
from atrophy in skeletal muscle. The precise mechanisms underpinning UBR5’s role in …

Metabolism and exercise: the skeletal muscle clock takes centre stage

RA Martin, MR Viggars, KA Esser - Nature Reviews Endocrinology, 2023 - nature.com
Circadian rhythms that influence mammalian homeostasis and overall health have received
increasing interest over the past two decades. The molecular clock, which is present in …

[HTML][HTML] Lamin-related congenital muscular dystrophy alters mechanical signaling and skeletal muscle growth

DJ Owens, J Messéant, S Moog, M Viggars… - International Journal of …, 2020 - mdpi.com
Laminopathies are a clinically heterogeneous group of disorders caused by mutations in
the LMNA gene, which encodes the nuclear envelope proteins lamins A and C. The most …

Mechanical loading of bioengineered skeletal muscle in vitro recapitulates gene expression signatures of resistance exercise in vivo

…, PP Gorski, RA Seaborne, M Viggars… - Journal of Cellular …, 2021 - Wiley Online Library
Understanding the role of mechanical loading and exercise in skeletal muscle (SkM) is
paramount for delineating the molecular mechanisms that govern changes in muscle mass. …

[HTML][HTML] Multi-omic identification of key transcriptional regulatory programs during endurance exercise training

GR Smith, B Zhao, ME Lindholm, A Raja, M Viggars… - bioRxiv, 2023 - ncbi.nlm.nih.gov
Transcription factors (TFs) play a key role in regulating gene expression and responses to
stimuli. We conducted an integrated analysis of chromatin accessibility, DNA methylation, and …

PCM1 labeling reveals myonuclear and nuclear dynamics in skeletal muscle across species

MR Viggars, DJ Owens, C Stewart… - … of Physiology-Cell …, 2023 - journals.physiology.org
Myonuclei transcriptionally regulate muscle fibers during homeostasis and adaptation to
exercise. Their subcellular location and quantity are important when characterizing phenotypes …

[HTML][HTML] Early morning run-training results in enhanced endurance performance adaptations in mice

SJ Hesketh, CL Sexton, CA Wolff, MR Viggars… - bioRxiv, 2023 - ncbi.nlm.nih.gov
Time-of-day differences in acute exercise performance in mice are well established with late
active phase (afternoon) runners exhibiting significantly greater endurance performance …
