It has been hypothesized that miR‑222‑3p may influence wound healing via the regulation of angiogenesis. To elucidate the underlying mechanism, experimental investigations were conducted <i>in vitro</i> using human dermal microvascular endothelial cells (HMEC‑1) and <i>in vivo</i> in a mouse model of streptozotocin‑induced diabetes. Methylglyoxal (MGO), a glycolytic intermediate, is known to contribute to diabetic vascular complications. The results demonstrated that MGO‑treated HMEC‑1 cells exhibited an increased expression of miR‑222‑3p and impaired microvascular endothelial cell function. The overexpression of miR‑222‑3p in MGO‑treated HMEC‑1 cells further suppressed cell proliferation, migration and tube formation, while it enhanced apoptosis. Moreover, the upregulation of miR‑222‑3p reduced the expression of apelin (APLN), and dual‑luciferase reporter assays confirmed APLN as a direct downstream target of miR‑222‑3p. The silencing of APLN markedly impaired HMEC‑1 cell function. Notably, both the exogenous supplementation with Apelin‑13 and the overexpression of APLN significantly reversed endothelial dysfunction caused by the upregulation of miR‑222‑3p. <i>In vivo</i>, in both normal and diabetic mice, the elevated expression of miR‑222‑3p in skin wounds reduced APLN levels in the peri‑wound tissue and impaired wound healing. However, the overexpression of APLN or the inhibition of miR‑222‑3p with an antagomiR reversed this impairment. Collectively, these results suggest that miR‑222‑3p impairs microvascular endothelial cell function by targeting APLN, thereby contributing to delayed wound healing in diabetic skin.</p>","PeriodicalId":14086,"journal":{"name":"International journal of molecular medicine","volume":"58 5","pages":""},"PeriodicalIF":8.5,"publicationDate":"2026-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13637565/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149109237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present review summarizes the biological characteristics and regulatory mechanisms of ILC3s, while discussing their interactions with the gut microbiota and pathological functions in mucosa‑associated disorders. Derived from bone marrow‑resident common lymphoid progenitors, ILC3s differentiate under the transcriptional control of retinoid‑related orphan receptor γ‑t into distinct functional subsets, including natural cytotoxicity receptor (NCR)+ ILC3s, NCR‑ ILC3s and lymphoid tissue inducer cells. ILC3s maintain epithelial barrier integrity, enhance antimicrobial defense and support lymphoid tissue development through the production of effector molecules such as IL‑22, IL‑17 and granulocyte‑macrophage colony‑stimulating factor. These subsets can undergo phenotypic conversion in response to microenvironmental signals. ILC3 activity is tightly regulated by transcription factors, metabolic pathways, neuroimmune interactions and the circadian clock system. In addition, ILC3s establish bidirectional interactions with the gut microbiota: Microbial metabolites regulate ILC3 activity, whereas ILC3s influence microbial composition through IL‑22‑dependent antimicrobial peptide production and IgA responses. Depending on subset composition, local cytokine networks and tissue microenvironment, ILC3s may exert either pathogenic or protective effects in a number of diseases. Future investigations should aim to further elucidate the molecular mechanisms underlying ILC3 subset plasticity, tissue‑specific interaction networks and clinically translatable strategies for targeted intervention. Building upon these findings, the present review proposes a spatiotemporal‑quantitative framework and three regulatory axes that may account for disease‑specific variations in ILC3 responses, providing a basis for understanding distinct ILC3 functions and developing targeted therapeutic strategies. Systematic investigation of the regulatory principles governing ILC3 biology will not only deepen the understanding of innate immune homeostasis but also provide potential targets and strategies for precision immunotherapy in diseases such as inflammatory bowel disease and colorectal cancer.</p>","PeriodicalId":14086,"journal":{"name":"International journal of molecular medicine","volume":"58 5","pages":""},"PeriodicalIF":8.5,"publicationDate":"2026-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13600334/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148989863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conservative treatment is the cornerstone of KOA management, and when it proves insufficient, extracorporeal shock wave therapy (ESWT) has emerged as a practical non‑invasive alternative. The present narrative review systematically summarizes current preclinical and clinical evidence on ESWT for KOA through a structured literature search, aiming to integrate its therapeutic effects and identify knowledge gaps. Accumulating evidence indicates that ESWT can slow KOA progression through multiple biological pathways, encompassing anti‑inflammatory, anti‑apoptotic, pro‑proliferative and cartilage‑protective effects, while also relieving pain and improving function clinically. Summarizing the available data, this review finds that ESWT exhibits a favorable safety profile for articular tissues and disease‑modifying potential in preclinical models, although treatment outcomes depend critically on energy flux density and protocol selection. In human studies, the current evidence primarily supports symptomatic relief, including pain reduction and functional improvement; high‑quality trials with structural endpoints to verify cartilage regeneration or joint space preservation remain scarce. Given its non‑invasive nature, safety and growing clinical support, ESWT merits consideration as an adjunctive therapy. However, heterogeneity in treatment parameters and limited long‑term data preclude standardized guidelines. Despite these limitations, ESWT remains a promising adjunctive therapy for patients who are unresponsive to conventional conservative treatments.

Using a mouse MIRI model, the effects of RMZ on cardiac function, cell death, lipid peroxidation, Fe²⁺ accumulation and ferroptosis‑related markers were assessed, together with transmission electron microscopy (TEM) imaging. Transcriptomic analysis identified ferroptosis signatures in cardiomyocytes (CMs). Ferrostatin‑1 (Fer‑1) served as a positive control to validate the anti‑ferroptotic effects of RMZ.

In the MIRI model, mice treated with RMZ exhibited greater resistance to MIRI, as evidenced by improved cardiac function, reduced myocardial injury markers and decreased TUNEL‑positive CMs. Transcriptomic analysis indicated the activation of ferroptosis following MIRI.
