To elucidate potential toxicological mechanisms, we employed network toxicology and molecular docking, further validated by 100\u2009ns molecular dynamics (MD) simulations. Additionally, bulk genomic cohorts (e.g., TCGA, METABRIC) and single\u2010cell RNA sequencing (scRNA\u2010seq) datasets were utilized to assess mutation patterns and delineate key targets within the tumor microenvironment (TME).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Analysis of 22,143 AE reports yielded 133 significant safety signals, predominantly involving metabolism (e.g., hyperglycemia), the gastrointestinal system (e.g., nausea, stomatitis), and dermatological conditions (e.g., rash). Pathway enrichment highlighted the PI3K\u2010AKT, HIF\u20101, and EGFR signaling networks. Integrative analyses identified critical toxicity\u2010related modulators, notably AKT1, IGF1, PTEN, TP53, and GSK3B. Crucially, MD simulations robustly confirmed the thermodynamic stability of the capivasertib\u2013GSK3B complex. Genomic profiling revealed pronounced mutual exclusivity among PIK3CA, AKT1, and PTEN alterations. Furthermore, scRNA\u2010seq analysis demonstrated that GSK3B overexpression defines a highly aggressive, proliferative malignant subpopulation that profoundly reshapes intercellular communication with stromal fibroblasts.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>By seamlessly bridging real\u2010world pharmacovigilance with advanced structural biology and single\u2010cell transcriptomics, this study delineates the comprehensive safety landscape of capivasertib.
