The STING1 gene (stimulator of interferon genes 1) plays a critical role in innate immunity by recognizing abnormal DNA and activating immune signaling pathways, promoting the expression of type I interferons and pro-inflammatory cytokines, thereby enhancing anti-tumor immune responses. Liquiritigenin (LQG), a flavonoid compound extracted from licorice, exhibits anti-inflammatory, antioxidant, and anti-cancer properties, capable of inhibiting tumor cell proliferation and invasion while regulating autophagy. This study aims to evaluate the role of LQG in regulating the STING1 gene and its anti-cancer mechanisms in bladder cancer.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Methods&lt;/h3&gt;&lt;div&gt;This study employed a multidimensional approach, combining bioinformatics analysis with both in vitro and in vivo experimental validation. Bioinformatics was utilized to assess the expression, function, and immune-related analyses of the STING1 gene. In vitro experiments included CCK-8 assays and colony formation assays to evaluate cell proliferation; Transwell migration assays and wound healing assays to assess migratory capacity; flow cytometry to analyze apoptosis; and immunofluorescence to observe the accumulation of autophagosomes. Additionally, molecular docking analysis was conducted to explore the interaction between LQG and the STING protein, while Western blotting was used to elucidate key molecular pathways. In vivo studies employed a mouse xenograft tumor model to systematically evaluate the anti-tumor effects and safety of LQG.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Results&lt;/h3&gt;&lt;div&gt;The results showed that STING1 expression was significantly lower in bladder cancer tissues compared to normal tissues. Functional enrichment analysis indicated a close relationship between STING1 and immune response regulation. High STING1 expression was positively associated with different types of immune cells and important immune checkpoints. Analysis of immunotherapy indicated that high STING1 expression was associated with favorable clinical responses. Molecular docking confirmed that LQG directly targets the STING protein. Experimental results demonstrated that LQG inhibits tumor cell survival by targeting STING and blocking autophagic flux. Additionally, LQG downregulated the expression of MMP2 and MMP9, inhibiting migration and invasion, while enhancing apoptosis by modulating Bcl-2, Bax, and caspase-3 levels.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Conclusion&lt;/h3&gt;&lt;div&gt;These findings underscore the critical role of STING1 in the immunobiology of bladder cancer, indicating its potential as a therapeutic target and biomarker for immunotherapy.

Therefore, this study aimed to construct an immune prognostic model for glioblastoma by analyzing enriched biological processes and pathways in tumors.</div></div><div><h3>Methods</h3><div>A comprehensive single-sample gene set enrichment analysis (ssGSEA) of gene sets from the Molecular Signatures Database was performed using TCGA RNA sequencing data (141 glioblastoma cases). After evaluating gene sets associated with prognosis using univariable Cox regression, gene sets related to biological processes and tumor immunity in gliomas were extracted. Finally, the least absolute shrinkage and selection operator Cox regression refined the gene sets and a nomogram was constructed. The model was validated using CGGA (183 cases) and Aichi Cancer Center (42 cases) datasets.</div></div><div><h3>Results</h3><div>The immune prognostic model consisted of three gene sets related to biological processes (sphingolipids, steroid hormones, and intermediate filaments) and one related to tumor immunity (immunosuppressive chemokine pathways involving tumor-associated microglia and macrophages). Kaplan-Meier curves for the training (TCGA) and validation (CGGA) cohorts showed significantly worse overall survival in the high-risk group compared to the low-risk group (<em>p</em> &lt; 0.001 and <em>p</em> = 0.04, respectively). Furthermore, in silico cytometry revealed a significant increase in macrophages with immunosuppressive properties and T cells with effector functions in the high-risk group (<em>p</em> &lt; 0.01) across all cohorts.</div></div><div><h3>Conclusion</h3><div>Construction of an immune prognostic model based on the TIME assessment using ssGSEA could potentially provide valuable insights into the prognosis and immune profiles of patients with glioblastoma and guide treatment strategies.</div></div>","PeriodicalId":49225,"journal":{"name":"Cancer Genetics","volume":"294 ","pages":"Pages 32-41"},"PeriodicalIF":1.4,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143681123","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}
