Multifaceted Integrated Analysis of CDK1 and TOP2A Signaling Pathways for Multi-Target Therapeutic Intervention in Epithelial Ovarian Cancer.

Epithelial ovarian cancer (EOC) remains one of the most aggressive gynecological malignancies, largely due to late-stage diagnosis, therapeutic resistance, and molecular heterogeneity. This study aimed to identify biologically relevant hub genes and evaluate potential dual-target compounds against Cyclin-Dependent Kinase 1 (CDK1) and DNA Topoisomerase II Alpha (TOP2A) through an integrated computational framework. Transcriptomic datasets from GSE28799, GSE54388, and GSE14407 were analyzed to identify overlapping differentially expressed genes, followed by protein-protein interaction analysis, functional enrichment, survival assessment, molecular docking, ADMET profiling, and molecular dynamics simulations. Mechanistically, CDK1 and TOP2A participate in coordinated cell-cycle regulation associated with G2/M progression and chromosomal dynamics in ovarian cancer. Among the identified hub genes, CDK1 and TOP2A demonstrated marked overexpression and central topological importance within the interaction network. Functional enrichment analyses highlighted significant associations with mitotic cell-cycle regulation, DNA replication, and proliferative signaling pathways. Molecular docking analyses identified Naringin as a potential dual-target candidate with favorable binding affinity toward both CDK1 and TOP2A. ADMET profiling suggested acceptable pharmacokinetic and toxicity characteristics, while molecular dynamics simulations supported stable protein-ligand interactions under dynamic conditions. Although survival analyses did not demonstrate statistically significant independent prognostic associations, the findings support the biological relevance of CDK1 and TOP2A in EOC progression. Collectively, this study provides an integrated computational perspective on CDK1/TOP2A-associated oncogenic signaling and prioritizes Naringin as a preliminary candidate for future experimental investigation in epithelial ovarian cancer.
