Distributions of circRNAs in human chromosomes in ovarian cancer stem cells. A Scatter plots representing differentially expressed circRNAs in ovarian cancer stem cells. circRNAs above and below the border green line show more than twofold change in expression. B The volcano plots representing differentially expressed circRNAs between groups. The green vertical line marks twofold changes, while the horizontal line represents a P-value of 0.05. Distribution of differentially upregulated (C) and downregulated D circRNAs between ovarian cancer stem cells and monolayer cells in human chromosomes. The ratio of circRNAs originated from exonic, intronic, and intergenic regions are shown. E The circRNA_004766, circRNA_008603, circRNA_004908 level of the GSE192410 dataset, which contains information on ovarian cancer tumour tissue
