Proteomic Profiling of Myofiber Repair Annexins and Their Role in Duchenne Muscular Dystrophy

PROTEOMICS, EarlyView.
ABSTRACT Myofiber regeneration and membrane repair play crucial roles in maintaining the continuous physiological functioning of the neuromuscular system. A swift and efficient repair mechanism enables the rapid restoration of sarcolemmal integrity following cellular impairment in damaged skeletal muscles.

Impact of TIEG1 Deletion on the Passive Mechanical Properties of Fast and Slow Twitch Skeletal Muscles in Female Mice.

PLoS ONE, 2016
As transforming growth factor (TGF)-β inducible early gene-1 is highly expressed in skeletal muscle, the effect of TIEG1 gene deletion on the passive mechanical properties of slow and fast twitch muscle fibers was analyzed. Twenty five muscle fibers were

Muscle fatigue in patients with severe long COVID: A 2‐year follow‐up study

PM&R, EarlyView.
Abstract Background Fatigue is recognized as one of the most persistent and debilitating symptoms of long COVID, affecting both functionality and quality of life. However, its long‐term effects, especially beyond the first year after infection, remain poorly understood.

Effects of Muscle Fiber Composition on Meat Quality, Flavor Characteristics, and Nutritional Traits in Lamb

Foods
Skeletal muscle fiber type composition critically influences lamb meat quality. This study examined the relationships between muscle fiber types and key quality traits, including tenderness, color, lipid and amino acid profiles, and volatile flavor ...

Re‐thinking peripheral dysfunctions in obesity: The emerging role of sulphaceutics and sulphanutraceutics

British Journal of Pharmacology, EarlyView.
Obesity is a chronic, relapsing, multisystem disease in which cardiometabolic risk arises from excess adiposity and progressive dysfunction of peripheral organs, ultimately disrupting endocrine and metabolic crosstalk among tissues. Within this network, sulphur‐based biology, centred on hydrogen sulphide and related reactive sulphur species, has ...

Vestigial-like 2 contributes to normal muscle fiber type distribution in mice

Scientific Reports, 2017
Skeletal muscle is composed of heterogeneous populations of myofibers that are classified as slow- and fast-twitch fibers. The muscle fiber-type is regulated in a coordinated fashion by multiple genes, including transcriptional factors and microRNAs ...

The epigenetic landscape of skeletal muscle in response to exercise and aging

The FEBS Journal, EarlyView.
Epigenetic mechanisms regulate gene expression in response to exercise and aging, thereby supporting skeletal muscle plasticity. Acute exercise induces chromatin remodeling through histone modifications and DNA methylation, promoting the expression of exercise‐responsive genes.

Circadian disruption elicits sex‐specific gut microbiota, endocannabinoidome, and lipid mediator responses

The FEBS Journal, EarlyView.
Circadian disruption via constant light induces sex‐specific remodeling of the microbiome, lipid mediators, and immune responses. Females exhibit broader gut microbiota alterations, reduced jejunal oxylipins, increased hypothalamic N‐acylethanolamines, and a more inflammatory cytokine profile. Muscle responses are sex‐ and fiber type‐dependent: females

Azilsartan prevents muscle loss and fast- to slow-twitch muscle fiber shift in natural ageing sarcopenic rats

Canadian Journal of Physiology and Pharmacology
Sarcopenia is a musculoskeletal disease that reduces muscle mass and strength in older individuals. The study investigates the effects of azilsartan (AZL) on skeletal muscle loss in natural sarcopenic rats. Male Sprague-Dawley rats aged 4–6 months and 18–21 months were selected as young-matched control and natural-aged (sarcopenic) rats, respectively.

Mitophagy in skeletal muscle: Impact of ageing, exercise and disuse

Experimental Physiology, EarlyView.
Abstract Skeletal muscle plays an important role in whole‐body health, quality of life and regulation of metabolism. The maintenance of a healthy mitochondrial pool is imperative for the preservation of skeletal muscle quality and is mediated through mitochondrial quality control consisting of mitochondrial turnover mediated by a balance between ...
