Our study was designed to explore the impact of MDM2 overexpression on the levels of various cell cycle regulatory proteins including Aurora kinase-B (AURK-B), CDC25C and CDK1, which are known to promote tumor progression and increase metastatic potential.
Cell viability, DNA damage and the mRNA expression of the CDC25C (cell division cycle 25C), CDKN1A (cyclin dependent kinase inhibitor 1A) and CHEK1 (checkpoint kinase 1), SQSTM1 (sequestosome 1) and ULK1 (unc-51 like autophagy activating kinase 1), RELA (RELA proto-oncogene, NF-κB subunit) and TP53BP1 (tumor protein p53 binding protein 1) genes important in cell cycle regulation, autophagy and cancer progression were investigated.
