Identification of DEGs in GSE 15372, GSE33482, GSE45553, GSE58470 and GSE73935. Heat maps and volcano plots of DEGs obtained from the GSE15372 dataset (A), GSE33482 dataset (B), GSE45553 dataset (C), GSE58470 dataset (D), GSE73935 dataset (E). Hierarchical clustering analysis of DEGs, which were differentially expressed between cisplatin-sensitive and cisplatin-resistant cell lines of OC (> twofold different in expression and P < 0.05). Volcano plots were constructed using fold-change value and adjusted P. The red point in the plot represents the up- regulated genes and green point represents the down- regulated genes with statistical significance
