Integrated study reveals molecular mechanisms by which bisphenol A promotes ovarian cancer

Bisphenol A (BPA) is an endocrine-disrupting chemical, and long-term low-level exposure is closely associated with ovarian cancer (OC). However, the underlying molecular mechanisms remain unclear. Utilizing the Comparative Toxicogenomics Database (CTD) and the Gene Expression Profiling Interactive Analysis (GEPIA) database, combined with LASSO Cox regression, we constructed a BPA exposure-associated OC risk prognosis model composed of CDKN1B, TIPARP, DYRK1B, EPCAM, and WDR77. Functional analysis indicated that the risk model and its constituent genes are associated with humoral immune activation and cellular immunosuppression. Furthermore, the activation of neuroactive ligand-receptor interaction signaling appears to be a common molecular mechanism through which these risk genes contribute to OC. Molecular docking, molecular dynamics simulations, and cellular experiments confirmed a stable binding interaction between BPA and the CDKN1B protein. These findings provide scientific data for a deeper understanding of the molecular mechanisms linking BPA to OC, aiding risk prediction and personalized prevention for exposed individuals.
