TOP2A is involved in p53 pathway. A. By analyzing GEO and TCGA databases, 148 mRNAs were found in TOP2A high and low groups. KEGG pathway enrichment analysis showed the top 3 most enriched pathways were Oocyte meiosis, p53 signaling pathway and Viral carcinogenesis, respectively. B. The heat map indicated significantly differentially expressed genes of P53 pathway between TOP2A-high and TOP2A-low group. CCNB1, CCNE2, CDK1, CCNB2, RRM2, CHEK1 and PMAIP1 were significantly upregulated in TOP2A high expression group. C. The expression levels of CCNB1, CCNB2 and CHEK1 were further identified by the violet plots, which demonstrated these genes expression levels were positively related to TOP2A. D. The expression levels of p53 related genes (cyclinB1 (CCNB1), cyclinB2 (CCNB2), CHEk1, MDM2, p53) in GLC82 and A549 cells with transfected TOP2A siRNA or control were identified by Western blot. Downregulation of the expression levels of CCNB1, CCNB2 and CHEk1 was observed in lung adenocarcinoma cells with siRNA compared with control. There was no difference in the expression levels of p53 and MDM2 between siRNA and control groups. These results indicated that TOP2A regulates the expression levels of p53 pathway related genes.
