PPARs are primarily recognized for their critical role in lipid and glucose metabolism, which underpins their therapeutic applications in managing type 2 diabetes mellitus. Beyond metabolic disorders, they have gained attention for their involvement in immune modulation, making them potential targets for autoimmune-related inflammatory diseases. Furthermore, PPAR's ability to regulate proliferation, differentiation, and apoptosis has positioned them as promising candidates in oncology. Their anti-inflammatory and anti-fibrotic properties further highlight their potential in dermatological and cardiovascular conditions, where dysregulated inflammatory responses contribute to disease progression. Recent advancements have elucidated the molecular mechanisms of different PPAR isoforms, including their regulation of key signalling pathways such as NF-κB and MAPK, which are crucial in inflammation and cellular stress responses. Additionally, their interactions with co-factors and post-translational modifications further diversify their functional roles. The therapeutic potential of various PPAR agonists has been extensively explored, although challenges related to side effects and target specificity remain. This growing body of evidence underscores the significance of PPARs in understanding the molecular basis of diseases and advancing therapeutic interventions, paving way for targeted treatment approach across a wide spectrum of medical conditions. Here, we provide a comprehensive and detailed perspective of PPARs and their potential across different health conditions to advance our understanding, elucidate underlying mechanisms, and facilitate the development of potential treatment strategies.</div></div>","PeriodicalId":13859,"journal":{"name":"International immunopharmacology","volume":"155 ","pages":"Article 114616"},"PeriodicalIF":4.8,"publicationDate":"2025-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143824550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The epithelial–mesenchymal transition (EMT), a fundamental biological process in cancer proliferation and progression, is intricately linked to the interactions between TAMs and cancer cells. However, the underlying mechanisms of EMT and how EMT-programmed cancer cells specifically modulate Arg1 expression in M2-like TAMs remain incompletely understood. Our comprehensive analysis confirmed that Arg1 expression was significantly upregulated in non-small cell lung cancer (NSCLC) tissues, and patients with elevated Arg1 levels exhibited a notably shorter overall survival. Furthermore, alterations in miR-135a-5p expression were found to profoundly influence the proliferation, migration, invasion, EMT, and apoptotic processes of NSCLC cells. Mechanistically, miR-135a-5p post-transcriptionally inhibited STAT6 expression by regulating its 3′-untranslated region (3’-UTR). Subsequently, the miR-135a-5p/STAT6 axis inhibited GATA3-mediated interleukin-4 (IL-4) secretion from NSCLC cells, ultimately suppressing Arg1 expression in M2-like TAMs. MiR-135a-5p may exert pivotal roles in modulating STAT6-induced EMT in tumor cells, which subsequently impacts IL-4-related Arg1 expression and M2 polarization of TAMs in NSCLC. This, in turn, reduced the capacity of M2-like TAMs to secrete tumor-promoting cytokines. Therefore, Arg1 holds potential as a diagnostic biomarker for NSCLC, and miR-135a-5p may emerge as a promising target for inhibiting NSCLC progression.</div></div>","PeriodicalId":13859,"journal":{"name":"International immunopharmacology","volume":"155 ","pages":"Article 114623"},"PeriodicalIF":4.8,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143811332","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
