Ubiquitin Ligases at the Heart of Skeletal Muscle Atrophy Control

Molecules, 2021
Skeletal muscle loss is a detrimental side-effect of numerous chronic diseases that dramatically increases mortality and morbidity. The alteration of protein homeostasis is generally due to increased protein breakdown while, protein synthesis may also be

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Inhibiting 5‐lipoxygenase prevents skeletal muscle atrophy by targeting organogenesis signalling and insulin‐like growth factor‐1

Journal of Cachexia, Sarcopenia and Muscle, 2022
Background Skeletal muscle atrophy can occur in response to numerous factors, such as ageing and certain medications, and produces a major socio‐economic burden. At present, there are no approved drugs for treating skeletal muscle atrophy. Arachidonate 5‐

Molecular Mechanisms of Muscle Atrophy [PDF]

Cell, 2004
Skeletal muscle atrophy has extreme adverse consequences. Molecular mechanisms that mediate the process of atrophy are not well defined. Recent studies have focused on diverse molecular cascades that control the activation of ubiquitin ligases, indicating that the involvement of the ubiquitin proteasome may be common to a range of atrophic stimuli.

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

Molecular 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 ...

Heme oxygenase-1: A potential therapeutic target for improving skeletal muscle atrophy

Experimental Gerontology, 2023
Skeletal muscle atrophy is a common muscle disease that is directly caused by an imbalance in protein synthesis and degradation. At the histological level, it is mainly characterized by a reduction in muscle mass and fiber cross-sectional area (CSA ...

Muscle fiber atrophy

Rinsho Shinkeigaku, 2012
Muscle fibers have been classified into two major forms of red (slow twitch) and white (fast twitch) muscles. The red muscle utilizes lipid as energy source through mitochondrial metabolism and function to sustain the position against gravity (sometimes called as antigravity muscle). Under microgravity the red muscle is selectively involved.

Circulating microRNA signatures of cachexia and cancer in Canis familiaris as a comparative oncology model for human disease

Molecular Oncology, EarlyView.
Circulating microRNAs as biomarkers of cachexia and sex‐specific cancer in senior dogs. In 25 client‐owned dogs, four circulating miRNAs (miR‐15a, miR‐15b, miR‐16, miR‐140) were downregulated in cachexia, with miR‐16 the strongest individual biomarker (AUC = 0.899).

Optineurin binding to the novel interacting partner Junction plakoglobin prevents muscle atrophy in mice.

PLoS Biology
Skeletal muscle atrophy is a debilitating condition that significantly affects patients' quality of life and prognosis, yet its underlying mechanisms remain poorly understood.
