Cervical squamous cell carcinoma (CESC) is the fourth most common malignancy and the fourth leading cause of cancer deaths in women worldwide. Despite advances in treatment, cisplatin-based radiotherapy remains the primary treatment option. However, cisplatin resistance is a major challenge, leading to poor prognosis. Therefore, understanding the molecular mechanisms underlying cisplatin resistance is crucial for developing novel therapeutic strategies. Through bioinformatics analysis, we investigated the expression of CDKN2A in the CESC database. WB, IHC, qPCR, and CCK-8 were used for clinical analysis of CDKN2A expression and its correlation with CESC cell proliferation. Through qPCR, CCK-8, ROS, MDA, Fe
