Abstract Mitochondria play important roles in maintaining cellular homeostasis and skeletal muscle health, damage to mitochondria can lead a series of pathophysiological changes. Mitochondrial dysfunction atrophy, its molecular mechanism leading atrophy is complex. Understanding the pathogenesis mitochondrial useful for prevention treatment finding drugs methods target modulate function are urgent tasks atrophy. In this review, we first discussed normal muscle. Importantly, described effect on mechanisms involved. Furthermore, regulatory different signaling pathways (AMPK-SIRT1-PGC-1α, IGF-1-PI3K-Akt-mTOR, FoxOs, JAK-STAT3, TGF-β-Smad2/3 NF-κB pathways, etc.) factors were investigated dysfunction. Next, analyzed manifestations caused by diseases. Finally, summarized preventive therapeutic effects targeted regulation including drug therapy, exercise diet, gene stem cell therapy physical therapy. This review great significance holistic understanding role muscle, which helpful researchers further has an inspiring development strategies targeting future.

Abstract Muscle wasting is a consequence of physiological changes or pathology characterized by increased catabolic activity that leads to progressive loss skeletal muscle mass and strength. Numerous diseases, including cancer, organ failure, infection, aging-associated are associated with wasting.

The Signal Transducer and Activator of Transcription (STAT)3 5 proteins are activated by many cytokine receptors to regulate specific gene expression mitochondrial functions. Their role in cancer is largely context-dependent as they can both act oncogenes tumor suppressors. We review here the STAT3/5 activation solid cancers summarize their association with survival patients. molecular mechanisms that underpin oncogenic activity signaling include regulation genes control cell cycle death.

Skeletal muscle requires a highly orchestrated coordination between multiple cell types and their microenvironment to exert its function maintain homeostasis regenerative capacity. Over the past decades, significant advances, including lineage tracing single-cell RNA sequencing, have contributed identifying resident populations participating in maintenance repair. Among these populations, stem cells (MuSC), also known as satellite cells, response stress or injury, are able proliferate, fuse, form new myofibers repair damaged tissue. These reside adjacent myofiber surrounded by specific complex microenvironment, niche. Major components of niche extracellular matrix (ECM) proteins, instruct MuSC behavior. However, during aging muscle-associated diseases, progressively loses ability, part due dysregulation ECM components. This review provides an overview composition importance microenvironment. We discuss relevant proteins how mutations impact young aged tissue contribute diseases. Recent discoveries improved our knowledge about skeletal muscle, which has helped mimic architecture capacity MuSC.

Acute kidney injury (AKI) is in high prevalence worldwide but with no therapeutic strategies. Programmed cell death tubular epithelial cells has been reported to accelerate a variety of AKI, the major pathways and underlying mechanisms are not defined. Herein, we identified that pyroptosis was responsible for AKI progression related ATP depletion renal cells. We found FAM3A, mitochondrial protein assists synthesis, decreased negatively correlated both mice patients AKI. Knockout FAM3A worsened function decline, increased macrophage neutrophil infiltration, facilitated ischemia/reperfusion model. Conversely, overexpression alleviated pyroptosis, inhibited ischemic Mechanistically, promoted PI3K/AKT/NRF2 signaling, thus blocking reactive oxygen species (mt-ROS) accumulation. NLRP3 inflammasome sensed overload mt-ROS then activated Caspase-1, which cleaved GSDMD, pro-IL-1β, pro-IL-18 into their mature forms mediate pyroptosis. Of interest, NRF2 activator pro-pyroptotic effects depletion, whereas deletion blocked anti-pyroptotic FAM3A. Thus, our study provides new demonstrates potential target treating
