In aging populations, sarcopenia often coexists with osteoporosis, forming osteosarcopenia, which markedly increases fracture risk, disability, and mortality. While traditional paradigms emphasize mechanical loading and endocrine pathways, emerging evidence has revealed that exosomes carrying bioactive miRNAs represent a novel class of paracrine factors in the muscle-bone axis. We examined how muscle-derived exosomal miRNAs (miR-34a and miR-27a-3p) influence bone metabolism, while bone-derived exosomal miRNAs (miR-486-5p) modulate muscle physiology. For each miRNA, we identified the target messenger RNAs (mRNAs) and signaling mechanisms. Importantly, exercise has emerged as a potent modulator of this crosstalk, altering exosomal miRNA profiles to promote anabolic outcomes in both tissues. This bidirectional communication contributes to osteosarcopenia pathophysiology, leading us to propose a novel “Exosomal miRNA Regulatory Network” for diagnosis and pathogenesis. Exosomal miRNAs show promise as early biomarkers for subclinical deterioration and therapeutic targets. However, methodological challenges in exosome isolation, incomplete characterization of miRNA networks, and aging complexity must be addressed before clinical implementation.</div></div>","PeriodicalId":18694,"journal":{"name":"Metabolism: clinical and experimental","volume":"170 ","pages":"Article 156333"},"PeriodicalIF":10.8,"publicationDate":"2025-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144366945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because of the close links in glycine and <span>l</span>-serine metabolism mediated by serine hydroxymethyltransferase (SHMT), decreased concentrations of both amino acids coincide in most glycine-deficient states. The consequence is a widespread impact on metabolism, including altered synthesis of glutathione, collagen, nucleotides, and one‑carbon units, impaired antioxidant defense, cytoprotection, conjugation, and neurotransmission and increased levels of homocysteine and deoxysphingolipids. It can, therefore, be assumed that, rather than glycine alone, its coadministration with <span>l</span>-serine is more appropriate in glycine-deficient conditions.

Nonetheless, its implication in the development of diabetes-accelerated myocardial ischemia/reperfusion (I/R) injury (MI/RI) has yet to be clarified. Diabetic mice were constructed by streptozotocin (STZ) injection, and MI/RI was then induced by coronary artery occlusion and reperfusion. H9c2 cells were exposed to high glucose (HG) for 24 h, followed by hypoxia/reoxygenation (H/R) for 4 and 2 h, respectively. USP48 protein and mRNA levels were downregulated in MI/RI mice or H/R-exposed cardiomyocytes, but were unexpectedly upregulated in diabetic mice following MI/RI and H9c2 cells exposed to HG and H/R. Cardiac-specific deficiency of USP48 worsened cardiac dysfunction, increased post-ischemic infarction size, promoted mitochondrial damage in myocardial cells, accelerated cardiomyocyte inflammation, oxidative stress, and apoptosis in diabetic mice. Conversely, such pathological conditions were ameliorated by cardiac-specific overexpression of USP48. Proteomics and experimental validation showed that USP48 stabilized and upregulated calponin 1 (CNN1) to confer cardioprotection, since silencing CNN1 minimized the benefits of USP48 in diabetes-aggravated cardiomyocyte injury. RNA sequencing and experimental data demonstrated that the USP48/CNN1 axis inhibited the release of CXC motif chemokine ligand 1 (CXCL1) and CXCL2 through inactivating the ERK1/2 pathway. Eventually, blockade of CXCL1/2 with specific antibodies protected against diabetes-exacerbated MI/RI, akin to USP48 overexpression. Together, these results highlight USP48 as a potential therapeutic target for managing diabetes-aggravated MI/RI by regulating the CNN1/ERK1/2/CXCL1/2 signaling pathway.</div></div>","PeriodicalId":18694,"journal":{"name":"Metabolism: clinical and experimental","volume":"170 ","pages":"Article 156326"},"PeriodicalIF":10.8,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144272223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
