Decorin Deficiency Promotes D-Galactose-Induced Skeletal Muscle Atrophy and Fibrosis by Regulating ITGB1/Akt/mTOR Signalling Pathway.

BACKGROUND

Primary sarcopenia is an age-associated disorder with progressive and generalised loss of skeletal muscle strength and mass. Skeletal muscle fibrosis is one of the significant pathological manifestations of age-associated sarcopenia. Decorin, a small dermatan-sulfate proteoglycan, participates in extracellular matrix assembly....

Negative Impact of p21-Activated Kinase 4-Mediated AMP-Activated Protein Kinase Inhibition on Sarcopenia in Mice and Humans.

We recently identified that AMP-activated protein kinase (AMPK) α2 phosphorylation at S491 is mediated by p21-activated kinase 4 (PAK4), leading to muscular and systemic insulin resistance. This study examined how muscle PAK4 deletion affects atrophy in male mice and its...

The Monocrotaline Model of Hypertension Leads to Cachexia in Male but Not Female Mice.

BACKGROUND

The monocrotaline (MCT) model of cardiac cachexia is a pharmaceutical approach to pulmonary hypertension that has been used to study heart failure and muscle wasting in rodents; however, little is known of how this pyrrolizidine alkaloid leads to peripheral changes...

Skeletal muscle-derived IL-33 mediates muscle-to-bone crosstalk and regulates bone metabolism via CD8 + T cell-secreted CCL5.

BACKGROUND

Skeletal muscle-to-bone crosstalk may play critical roles in the association between muscle atrophy and bone loss. Here, we report a myokine, IL-33, which may mediate muscle-to-bone crosstalk.

METHODS

A cohort study was conducted to elucidate the associations among circulating IL-33, osteoporosis, and...

The mitochondrial-targeted antioxidant SkQ1 prevents skeletal muscle mitochondrial-apoptotic but not necroptotic signalling during ovarian cancer.

The degree to which mitochondrial-linked programmed cell death pathways contribute to skeletal muscle atrophy during cancer remains unknown. Here we combined a novel and robust mouse model of metastatic ovarian cancer with chronic administration of the mitochondrial-targeted antioxidant SkQ1 to...

Role of Branched-Chain Amino Acids in Mitigating Osteosarcopenia: An Experimental Study Using Ovariectomised Mice Models.

BACKGROUND

Osteosarcopenia, characterised by concurrent bone loss and muscle atrophy, presents a significant challenge in aging populations, particularly in postmenopausal women. The current therapeutic options potentially treat bone and muscle loss independently, highlighting the importance of an integrated approach. This study...

Drug Candidate BIO101 for Spinal Muscular Atrophy as Monotherapy or Combined With the Antisense Oligonucleotide ASO-10-27.

BACKGROUND

Spinal muscular atrophy (SMA) is a neuromuscular disease caused by loss of survival of motor neuron (SMN) protein inducing progressive muscle weakness and atrophy due to motor neurons degeneration. Despite benefits of SMN restoration therapies in patients, motor defects are...

Cistanche deserticola extract and its active components, echinacoside, ameliorate sarcopenia by activating the IGF-1/PI3K-AKT pathway to modulate ferroptosis.

BACKGROUND

Sarcopenia (SP) is characterized by progressive loss of skeletal muscle mass and function, and is a significant health burden in an aging society. Existing therapies have limited effectiveness. While ferroptosis plays a key role in sarcopenia, its regulatory mechanism remains...

Interplay Between mTORC1 Signaling and Iron Homeostasis in Muscle Atrophy.

The mechanistic target of rapamycin complex 1 (mTORC1) plays an important role in maintaining skeletal muscle homeostasis by regulating cell growth, protein degradation, and nutrient sensing. Beyond its role in muscle growth and atrophy, recent findings suggest that mTORC1 also...

CXCL14 Promotes Skeletal Muscle Mass Growth and Attenuates Lipopolysaccharide- and Dexamethasone-Induced Muscle Atrophy in Cultured Myotubes and Mouse Models.

BACKGROUND

Skeletal muscle mass is regulated by secretory factors derived from myofibers and muscle-resident cells. Identifying these factors and understanding their mechanisms is critical for combating muscle wasting disorders. This experimental study investigates the role of CXCL14, a chemokine primarily secreted...

CTRP9 as a myokine mitigates sarcopenia via the LAMP-2A/NLRP3 pathway.

Sarcopenia, a degenerative condition marked by progressive skeletal muscle atrophy and impaired regeneration, is closely associated with aging, chronic inflammation, and disrupted proteostasis. While macroautophagy has been extensively studied in this context, little of the role of chaperone-mediated autophagy (CMA)...

CSE/H 2S/SESN2 Signalling Mediates the Protective Effect of Exercise Against Immobilization-Induced Muscle Atrophy in Mice.

Hydrogen sulphide (H 2S), a gasotransmitter synthesized by cystathionine-γ-lyase (CSE), exhibits antioxidant properties and may mimic exercise-induced muscle protection. However, its mechanistic role in muscle atrophy and exercise intervention remains unclear. Six-month-old male wild-type (WT) and SESN2 knockout (SESN2 -/-)...
