Different Pattern in Circulating MicroRNA-22-3p Levels Between Patients With Primary Versus Secondary Sarcopenia.

Sarcopenia, characterized by decreased skeletal muscle mass and strength, is classified as "primary" (due to aging) or "secondary" (due to diseases). MicroRNA-22-3p (miR-22) regulates muscle differentiation and function. We assessed the diagnostic value of circulating miR-22 levels in patients with...

Role of Peptides in Skeletal Muscle Wasting: A Scoping Review.

<p><b>BACKGROUND</b></p><p>Systemic muscle wasting is a prevalent condition that predicts adverse health outcomes in aging and disease. Despite its clinical relevance, the development of predictive biomarkers and effective pharmacological therapies remains limited. Peptides have recently gained attention for their diverse bioactive...

Impaired cAMP-PKA-CREB1 signalling drives mitochondrial dysfunction in skeletal muscle during cancer cachexia.

Skeletal muscle wasting is a defining feature of cancer cachexia, a multifactorial syndrome that drastically compromises patient quality of life and treatment outcomes. Mitochondrial dysfunction is a major contributor to skeletal muscle wasting in cancer cachexia, yet the upstream molecular...

Primary-Stage Colon Cancer Impairs Muscle Energy Metabolism by Suppressing Mitochondrial Complex I Activity.

<p><b>BACKGROUND</b></p><p>Colon cancer (CC), the third most common cancer worldwide, is accompanied by cachexia in 30% of patients. Its associated muscle loss directly impairs therapeutic response and survival. Early intervention is crucial, yet the underlying mechanisms of early-stage muscle dysfunction remain...

A Creatinine-CAR Composite Index (CCAR) Optimized by Machine Learning for Prognosis in Cancer Cachexia.

<p><b>BACKGROUND</b></p><p>Cancer cachexia is a multifactorial syndrome associated with poor prognosis and impaired quality of life in cancer patients. However, survival prediction in cancer cachexia remains difficult due to the lack of reliable biomarkers.</p><p><b>METHODS</b></p><p>This retrospective cohort study analysed data from 1,367...

STX4 Is Indispensable for Mitochondrial Homeostasis in Skeletal Muscle.

<p><b>BACKGROUND</b></p><p>Mitochondrial homeostasis is vital for optimal skeletal muscle integrity. Mitochondrial quality control (MQC) mechanisms that are essential for maintaining proper functions of mitochondria include mitochondrial biogenesis, dynamics and mitophagy. Previously, Syntaxin 4 (STX4), traditionally considered a cell surface protein known...

Muscle Structure and Function Recovery: Adalimumab-Calcium Channel Synergy in Post-Ischemic Stroke Sarcopenia.

<p><b>BACKGROUND</b></p><p>Adalimumab, a TNF-α inhibitor, is widely used clinically. Recent studies suggest Adalimumab can improve muscle damage after ischemic stroke (IS), but its protective mechanisms remain unclear. This study investigates the effect of adalimumab on muscle structure post-IS and the role...

Targeting Progesterone Receptor Membrane Component 1 to Improve Muscle Development and Glucose Homeostasis.

<p><b>BACKGROUND</b></p><p>Type 2 diabetes mellitus (T2D) arises from the interplay between peripheral insulin resistance and pancreatic β-cell dysfunction, ultimately leading to impaired glucose utilization and chronic hyperglycemia. Despite therapeutic advances, the multifactorial nature of T2D continues to demand the development of...

Rethinking Muscle Aging Through the Lens of Fibro-Adipogenic Progenitors.

Aging of skeletal muscles is accompanied by a progressive deposition of adipose and fibrotic tissue within the interstitial compartment. This process profoundly disrupts the structural integrity and contractile function of the muscle. Such maladaptive remodeling not only compromises muscle performance...

An Isogenic Human Myoblast Cell Model for Cystinosis Myopathy Reveals Alteration of Key Myogenic Regulatory Proteins.

<p><b>BACKGROUND</b></p><p>Cystinosis is a rare multisystem, autosomal recessive disease caused by dysfunction or loss of cystinosin (CTNS), which results in lysosomal cystine accumulation, primarily affecting the kidneys. Advances in renal transplantation, cysteamine treatment and improved medical care have increased life expectancy,...
