PACS2 Alleviates Sepsis-Induced Myopathy by Activating ERK-MAPK Signalling Pathway to Suppress ER-Phagy.

BACKGROUND

Sepsis-induced myopathy (SIM) is a common and life-threatening complication, but its underlying mechanisms remain poorly understood. PACS2, a key resident protein at mitochondria-associated endoplasmic reticulum membranes (MAMs), regulates ER homeostasis under various pathological conditions. However, whether sepsis disrupts PACS2-dependent MAM...

Juyuanjian attenuates sarcopenia through dual regulation of the Akt/FoxO1 and SIRT1/PGC-1α pathways.

BACKGROUND

Sarcopenia, an age-related degenerative disease, corresponds to "Qi Xu" syndrome in traditional Chinese medicine. Juyuanjian (JYJ), a classical Qi-tonifying formula, has shown potential against muscle atrophy and functional decline, but its molecular mechanisms are not well understood.

PURPOSE

To investigate whether JYJ...

RIPK3 Inhibition Mitigates Denervated Muscle Atrophy via NOX4-Mediated Mitochondrial Restoration and Inflammation Suppression.

BACKGROUND

Peripheral nerve injury-induced muscle atrophy shares core pathophysiological features with systemic wasting disorders including cachexia and sarcopenia, yet early molecular triggers remain undefined. This study investigates the pathogenic role of receptor-interacting protein kinase 3 (RIPK3) in denervation atrophy.

METHODS

Sciatic denervation was...

Deubiquitinase YOD1 Inhibition Suppresses DEX- and Denervation-Induced Muscle Atrophy Through MAFbx Destabilization.

BACKGROUNDS

Muscle atrophy, characterized by progressive loss of muscle mass and function, is driven by muscle-specific E3 ligases MAFbx and MuRF1. While transcriptional regulation of E3 ligases is documented, the mechanism of their regulation by the ubiquitin-proteasome system remains unclear. This...

Cancer IDO1-Mediated Tryptophan-Kynurenine Metabolic Reprogramming to Drive Skeletal Muscle Atrophy and Cachexia Acceleration.

BACKGROUND

Cancer cachexia is a debilitating syndrome characterized by severe skeletal muscle wasting, which significantly impairs patient quality of life and survival. Indoleamine 2,3-dioxygenase 1 (IDO1), a key enzyme in tryptophan (Trp) metabolism, is often upregulated in cancers, but its specific...

UNC45B Reduction With Aging: A Myofiber-Intrinsic Promoting Factor for Sarcopenia.

Skeletal muscle mass and force decline with age, and the loss of muscle force precedes muscle atrophy. However, the underlying mechanisms remain unclear. Here, we investigated the role of the myosin co-chaperone, uncoordinated mutant number-45 myosin chaperone B (UNC45B), in...

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.
