This research builds a computational framework to derive mast cell marker gene signatures (MCMGS) from a global cohort of 1091 prostate cancer patients, aiming to identify a robust predictive biomarker for prognosis and treatment selection. The study identifies mast cell-associated biomarkers across six international cohorts and develops MCMGS using multiple machine learning approaches. Immunological profiling, survival evaluation, and gene set and pathway analyses are applied to link the signature to therapeutic response mechanisms.",{"@graph":14,"@context":73},[15,34,56],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/research-report/","Research & Report",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/machine-learning-driven-mast-cell-gene-signatures-for-prognostic-and-therapeutic-prediction-in-prostate-cancer/328704/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/machine-learning-driven-mast-cell-gene-signatures-for-prognostic-and-therapeutic-prediction-in-prostate-cancer/328704.png","ImageObject",300,407,{"name":42,"@type":43},"Ezra","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-11-05","2026-09-21",true,{"@type":52,"interactionType":53,"userInteractionCount":55},"InteractionCounter",{"@type":54},"ViewAction",9,{"@type":57,"mainEntity":58},"FAQPage",[59,65,69],{"name":60,"@type":61,"acceptedAnswer":62},"What problem does the study address in prostate cancer research?","Question",{"text":63,"@type":64},"The study addresses the limited understanding of mast cells in prostate cancer prognosis and the inconsistent outcomes of immunotherapy.

Our research aims to employs a comprehensive computational methodology to evaluate Mast cell marker gene signatures (MCMGS) derived from a global cohort of 1091 PCA patients. This approach is designed to identify a robust biomarker to assist in prognosis and predicting responses to immunotherapy.  \nMethods: This study initially identified mast cell-associated biomarkers from prostate adenocarcinoma (PRAD) patients across six international cohorts. We employed a variety of machine learning techniques, including Random Forest, Support Vector Machine (SVM), Lasso regression, and the Cox Proportional Hazards Model, to develop an effective MCMGS from candidate genes. Subsequently, an immunological assessment of MCMGS was conducted to provide new insights into the evaluation of immunotherapy responses and prognostic assessments. Additionally, we utilized Gene Set Enrichment Analysis (GSEA) and pathway analysis to explore the biological pathways and mechanisms associated with MCMGS.  \nResults: MCMGS incorporated 13 marker genes and was successful in segregating patients into distinct high- and low-risk categories. Prognostic efficacy was confirmed by survival analysis  \nAbbreviations: PCA, Prostate Cancer; TCGA, The Cancer Genome Atlas; LASSO, The least absolute shrinkage and selection operator; MCMGS, Mast cell marker gene signature; BCR, Biochemical recurrence; CRPC, Castration-resistant prostate cancer; PSA, Prostate-specific antigen; AUC, Area under the curve; GEO, Gene Expression Omnibus; GO, Gene Ontology; KEGG, Kyoto Encyclopedia of Genes and Genomes; RSF, random survival forests; GBM, Generalized boosted regression modeling; GSEA, Gene Set Enrichment Analysis; TME, Tumor microenvironment; PFS, progression-free survival; TMB, tumor mutation burden.  \n* Corresponding author.
