Figure 5. Structural patterns of six differentially expressed circular (circ)RNAs. The features of four upregulated circRNAs, including hsa_circ_0000673, hsa_circ_0008274, hsa_circ_0060144, and hsa_circ_0072088 (A–D), and two downregulated circRNAs, including hsa_circ_0139402 and hsa_circ_0001714 (E and F), were visualized by Cancer-Specific CircRNAs Database.
