PPI network and core circRNA-miRNA-mRNA network. A PPI network composed of 165 nodes and 170 edges, and hub genes identified from the PPI network by Cytoscape. B The core circRNA-miRNA-mRNA network based on 1circRNA, 10 miRNAs, and the 18 hub genes. circRNA, circular RNA; miRNA, microRNA; mRNA, messenger RNA; PPI, protein-protein interaction
