Recent studies highlight the pivotal roles of macrophage migration inhibitory factor (MIF) and its homolog D-dopachrome tautomerase (DDT) in UV-induced skin carcinogenesis. This review aims to consolidate current knowledge of how MIF and DDT contribute to tumor initiation and progression under UV stress, with a focus on their biological functions, signaling pathways, and therapeutic potential.</p><p><strong>Methods: </strong>This narrative review synthesizes findings from basic, translational, and clinical studies examining MIF and DDT in the context of UV-mediated skin carcinogenesis. The literature was selectively reviewed to highlight mechanistic insights, pathological significance, and emerging therapeutic strategies.</p><p><strong>Results: </strong>Both MIF and DDT are upregulated upon UVB exposure and promote tumorigenesis by suppressing p53-mediated apoptosis, enhancing inflammatory signaling, and modulating the tumor immune microenvironment. Transgenic mouse models demonstrate that overexpression of either cytokine accelerates UVB-induced tumor formation, while inhibition reduces tumor burden. Although MIF and DDT share CD74-mediated pathways, they exhibit mechanistically distinct yet functionally complementary roles. In addition to melanoma, emerging evidence suggests involvement in non-melanoma skin cancers, particularly cutaneous squamous cell carcinoma (cSCC). Selective small-molecule inhibitors are under development, and expression profiles of MIF and DDT are being evaluated as biomarkers for prognosis and response to immunotherapy.</p><p><strong>Conclusion: </strong>MIF and DDT are critical mediators of UV-induced skin carcinogenesis. Their overlapping yet non-redundant signaling properties and emerging clinical relevance suggest that targeting these cytokines may offer new opportunities for prevention, diagnosis, and treatment of UV-induced skin cancers.</p>","PeriodicalId":20123,"journal":{"name":"Photodermatology, photoimmunology & photomedicine","volume":"41 5","pages":"e70046"},"PeriodicalIF":2.2,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144965007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
