In this regard, therapeutic modulation of damage‑associated molecular patterns (DAMPs)‑induced immunogenic cell death (ICD) may help improve the effect of immunotherapy in individuals with BC. The aim of this investigation was to develop biomarkers for ICD and to construct ICD‑related risk estimation models to predict prognosis and immunotherapy outcomes of BC. RNA‑ seq transcriptome information and medical data from individuals with BC (n = 943) were obtained  \nfrom TCGA. Expression data from a separate BC cohort (GEO: GSE20685) were used for validation. We identified subtypes of high and low ICD gene expression by consensus clustering and assessed the connection between ICD subtypes and tumor microenvironment (TME) . In addition, different algorithms were used to construct ICD‑based prognostic models of BC. BC samples were categorized into subtypes of high and low ICD expression depending on the expression of genes correlated  \nwith ICD. The subtype of ICD high‑expression subtypes are correlated with poor prognosis in breast cancer, while ICD low‑expression subtypes may predict better clinical outcomes. We also created and verified a predictive signature model depending on four ICD‑related genes (ATG5, CD8A, CD8B, and HSP90AA1), which correlates with TME status and predicts clinical outcomes of BC patients. We highlight the connection of ICD subtypes with the dynamic evolution ofTME in BC and present a novel ICD‑based prognostic model of BC. In clinical practice, distinction of ICD subtype and assessment of ICD‑related biomarkers should help guide treatment planning and improve the effectiveness of tumor immunotherapy.  \nAbbreviations  \nBC  \nDAMP  \nDEGs  \nGEO  \nGO  \nGSEA  \nHLA HMGB1 ICD  \nKEGG  \nKM  \nNK  \nOD  \nOS  \nPRRsqRT-pcr SDS-PAGE  \nBreast cancer  \nDamage-associated molecular pattern Differentially Expressed Genes  \nGene Expression Omnibus  \nGene Ontology  \nGene Set Enrichment Analysis  \nHuman leukocyte antigen  \nHigh mobility group proteins Immunogenic cell death  \nKyoto Encyclopedia of Genes and Genomes Kaplan–Meier  \nNatural killer  \nOptical density  \nOverall survival  \nPathogen recognition receptors Quantitative real-time PCR  \nSDS polyacrylamide gel electrophoresis  \n1Department of General Surgery, Panjin Liao-Oil Field Gem Flower Hospital, Panjin 124000, China. 2Department of Rheumatology and Immunology, Panjin Liao-Oil Field Gem Flower Hospital, Panjin 124000, China. *email: [zhengli_pj@163.com](zhengli_pj@163.com)  \n[www. nature.com/scientificreports/](www. nature.com/scientificreports/)  \nSNPs Single nucleotide polymorphisms  \nTIDE Tumor Immune Dysfunction and Exclusion  \nTME Tumor microenvironment  \nImmunogenic cell death (ICD) is the mechanism by which, following a death stimulus, tumor cells transition from a non-immunogenic to an immunogenic state to induce an anti-tumor immune response1,2. ICD is characterized by the release of a cascade of signaling molecules referred to as damage-associated molecular patterns (DAMPs). These include calreticulin, which is found on the surface of cells, high mobility group proteins (HMGB1), which are secreted by cancerous cells, and ATP molecules and heat shock proteins (HSP70, HSP90), which are produced by cells undergoing death. DAMPs released during ICD can trigger a series of cytological responses by binding to pathogen recognition receptors (PRRs) in the dendritic cells’ surface, ultimately activating the innate and adaptive immune reactions3–5. The identification of ICD as a crucial mechanism mediating tumor-directed immune responses provided a new direction for precision tumor treatment6","cbCaitWIWM8Vp2x8","https://ap.wps.com/l/cbCaitWIWM8Vp2x8","pdf",3525123,14,"English","# Materials and methods\n## Datasets and statistical analysis","[{\"question\":\"What was the goal of the study in breast cancer?\",\"answer\":\"To develop ICD-related biomarkers and risk estimation models that predict prognosis and immunotherapy outcomes in breast cancer.\"},{\"question\":\"How were ICD subtypes defined?\",\"answer\":\"By consensus clustering of ICD gene expression levels and evaluating associations with the tumor microenvironment.\"},{\"question\":\"What is the four-gene signature used for prediction?\",\"answer\":\"A predictive signature based on ATG5, CD8A, CD8B, and HSP90AA1, linked to tumor microenvironment status and clinical outcomes.\"}]","Immunogenic cell death-related classification reveals prognosis and effectiveness of immunotherapy in breast cancer | PDF",1790046575,35]
