The E3 ubiquitin ligase RNF200 has been implicated in the regulation of PD-L1 expression, yet its role in the context of radiotherapy is not well understood. To address this, non-small cell lung cancer (NSCLC) tissue samples from patients with and without prior radiotherapy were analyzed for RNF200 and PD-L1 expression using quantitative RT-PCR and Western blotting. Additionally, RAW264.7 macrophages were subjected to ionizing radiation and genetically manipulated to assess the impact of RNF200 on PD-L1 expression and stability through co-immunoprecipitation and ubiquitination assays. Co-culture experiments with macrophages and lung cancer cells were performed to evaluate the influence of RNF200 on radiotherapy sensitivity. In NSCLC tissues and macrophages, radiotherapy was found to downregulate RNF200 expression while upregulating PD-L1 expression. Overexpression of RNF200 led to marked suppression of PD-L1 expression, whereas RNF200 knockdown produced the opposite effect. Co-immunoprecipitation and ubiquitination assays revealed that RNF200 physically interacted with PD-L1 and promoted its polyubiquitination and proteasomal degradation. Furthermore, co-culture studies demonstrated that macrophages overexpressing RNF200 enhanced the sensitivity of lung cancer cells to radiotherapy, as evidenced by reduced proliferation, increased necrosis, and decreased secretion of transforming growth factor beta TGF-β. Collectively, these findings indicate that RNF200 enhances radiotherapy sensitivity in lung cancer by regulating PD-L1 expression through ubiquitination.

There is an urgent need for innovative treatment strategies. CAR-T therapy has shown revolutionary potential in the treatment of DLBCL, but its efficacy is limited by immune suppression and metabolic competition mediated by the tumor microenvironment (TME). Immunosuppressive cells and cytokines in the TME lead to the exhaustion of CAR-T cell functions, while metabolic competition puts CAR-T cells at a disadvantage in the uptake of key metabolites, limiting their proliferation and effector functions. Metabolic reprogramming, as a core mechanism of TME regulation, connects the functions of tumor cells and immune cells and is a key hub for enhancing the efficacy of CAR-T therapy. Among them, low glucose levels in the TME can activate the glycolytic pathway of CAR-T cells, but also lead to mitochondrial dysfunction and reduced cytotoxicity. Targeting the metabolic remodeling of the TME, in combination with metabolic regulatory drugs and CAR-T synergy strategies, as well as the development and translation of drugs, is expected to significantly enhance the efficacy of CAR-T therapy in the treatment of DLBCL, bringing new hope to patients. Future research should further explore the specific mechanisms of metabolic reprogramming, optimize the design and application of metabolic regulatory drugs, and accelerate the clinical translation of drugs to achieve the maximum potential of CAR-T therapy in the treatment of DLBCL.</p>","PeriodicalId":7437,"journal":{"name":"American journal of cancer research","volume":"15 8","pages":"3338-3358"},"PeriodicalIF":2.9,"publicationDate":"2025-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12432560/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145063252","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}
