BTC often exhibits an aggressive clinicopathological course [<span>1</span>]. Surgical resection remains the most curative treatment option for patients with BTC; however, it may be limited to the early stages of cancer [<span>1</span>]. Owing to their poor sensitivity to chemotherapeutic agents, new therapeutic approaches are required for patients with advanced BTC.</p><p>One of the remarkable pathological features of BTC is the dense fibrous stroma harboring cancer cell nests. It is well established that stromal cells play a crucial role in the tumor microenvironment. Therefore, several targeting therapies are attempted against cancer stroma. For example, lysyl oxidases (LOXs) are a family of five secreted copper-dependent amine oxidases (LOX and LOXL1–4) that promote carcinogenesis by generating cancer stroma. Very recently, Burchard et al. [<span>2</span>] demonstrated that PXS-5505, which is a small molecule inhibitor of all LOX isoforms, improved chemotherapeutic penetration and reduced the inflammatory reaction of intrahepatic cholangiocarcinoma, thereby enhancing antitumor immunity in autochthonous and orthotopic murine models. Unfortunately, efforts to target individual LOX isoforms have failed to achieve clinical impact, likely due to the compensatory action of other LOX family members. Combination therapies targeting multiple stromal components are warranted.</p><p>T-cadherin is an atypical cadherin attached to the plasma membrane by a glycosylphosphatidylinositol anchor without a cytosolic domain [<span>2</span>].

Immunohistochemical staining using a tissue microarray, with a core diameter of 1.5 mm, demonstrated T-cadherin immunoreactivity in cancer stromal niches in BTC, especially in the cancer invasion microenvironment with a desmoplastic reaction (Figure 1a–d). Furthermore, T-cadherin expression was detected in the endothelial cells of tumor vessels and stromal mesenchymal cells of all 27 intrahepatic cholangiocarcinomas and 32 of 43 extrahepatic biliary duct adenocarcinomas. Consistent with previous research [<span>3</span>], T-cadherin immunoreactivity was also observed in the endothelial cells of tumor-penetrating vessels in breast and colorectal cancers.

Additionally, whether any of the transcriptional regulations depend on tumor heterogeneity and the tumor microenvironment has not been investigated.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>We used bulk RNA-seq data to identify dysregulated polyamine metabolism genes and their transcription factors across breast cancer subtypes. Genes highly correlated with polyamine changes were obtained, and their subtype-specific expressions were checked in tumor microenvironment cells using single-cell RNA (scRNA)-seq data. Gene Ontology enrichment analysis was used to explore their molecular functions and biological processes, and survival analysis was used to examine the impact of these genes on therapeutic outcome.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>We first analyzed the dysregulation of polyamine synthesis, catabolism, and transport in four breast cancer subtypes. Genes such as <i>AGMAT</i> and <i>CAV1</i> were dysregulated across all subtypes, while <i>APRT</i>, <i>SAT1</i>, and other genes were dysregulated in the more lethal subtypes. Among the dysregulated genes of polyamine metabolism, we focused on three genes (<i>SRM</i>, <i>APRT</i>, and <i>SAT1</i>) and identified their transcription factors (SPI1 and IRF1 correspond to <i>SAT1</i>, and IRF3 corresponds to <i>SRM</i> and <i>APRT</i>). With scRNA-seq data, we verified that these three transcription factors also regulated these three polyamine metabolism genes in the tumor microenvironment. Both bulk RNA-seq and scRNA-seq data indicated that these genes were specifically upregulated in high-risk breast cancer subtypes, such as the basal-like type. High expression of these genes corresponded to worse outcomes in the basal-like subtype under chemotherapy and radiation treatment.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>Our work identified three subtype-specific transcription factors that regulate three polyamine metabolism genes in high-risk breast cancer subtypes and the tumor microenvironment. Our results deepen the understanding of the role of polyamine metabolism in breast cancer and may help the clinical therapy of advanced breast cancer subtypes.</p>\u0000 </section>\u0000 </div>","PeriodicalId":100212,"journal":{"name":"Cancer Innovation","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cai2.138","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142762076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
