Although accumulating evidence suggests that bacterial infection may be involved in the development of the metastasis of lung cancer, few studies have explored the molecular mechanisms of bacterial infection in the dissemination of lung cancer cells. A series of studies have indicated that certain Gram-negative bacteria are able to hijack antigen-presenting cells (APCs) via interaction with DC-SIGN (CD209) receptors to facilitate the dissemination of pathogens, including viruses, bacteria, fungi, and parasites. Therefore, in the present work, it was hypothesized that bacterial infection may promote the dissemination of cancer cells via the utilization of a similar mechanism. It was first discovered that human lung cancer tissues contain a very high diversity of bacterial DNAs, indicating the co-existence of lung cancer tissues and microbial organisms. It was then found that lung cancer tissues express DC-SIGN, leading to binding with a Gram-negative bacterium, Shigella sonnei. Further, this bacterium was found to be able not only to induce the expression of DC-SIGN on macrophages but also to enhance the migration ability of lung cancer cells in vitro. The in vivo experiments supported these observations, showing that in wild-type (WT) mice, Shigella sonnei infection significantly increased tumor size, weight, and metastatic nodules compared to SIGNR1 knockout (KO) mice. These observations were associated with increasing DC-SIGN expression in WT mice. Finally, these results suggest that bacterial infections could play a significant role in promoting lung cancer progression and metastasis via DC-SIGN-mediated mechanisms.</p>","PeriodicalId":13568,"journal":{"name":"Infectious Agents and Cancer","volume":"20 1","pages":"40"},"PeriodicalIF":3.1,"publicationDate":"2025-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12181914/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144340064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent studies have shown that viruses from the HERV family play a significant role in the development of various cancers and can act as early diagnostic biomarkers. Although hypomethylation of HERV-K has been proven in bladder cancer, no studies have yet explored the role of HERV-K oncogenes such as env, gag, np9, and rec.

Bone marrow stromal cell antigen 2 (BST2) is a transmembrane glycoprotein, and its promoter methylation has been extensively documented in numerous human cancers. Nevertheless, the specific role of BST2 in CC remains unclear. This research utilized methylation-specific PCR (MSP), Western blotting, and RT-qPCR to evaluate the expression and DNA methylation levels of BST2 in CC tissues and cells. The role of STAT1 in regulating BST2 transcription was confirmed through dual-luciferase reporter assays and chromatin immunoprecipitation (ChIP) assays. Furthermore, we conducted experiments on cell proliferation, apoptosis, epithelial-mesenchymal transition (EMT), and xenograft tumor models to investigate the functional role and regulatory mechanisms of BST2 in CC, both in vitro and in vivo. We found that BST2 was increased in CC tissues and cells, promoting cell proliferation and EMT while inhibiting apoptosis. Mechanistically, BST2 upregulation was associated with hypomethylation of its promoter, potentially regulated by DNMT3a and DNMT3b. Furthermore, the transcription factor STAT1 was found to bind to the BST2 promoter, positively regulating its expression and thereby accelerating tumorigenesis in CC. Silencing BST2 significantly reduced tumor growth in vivo.
