Figure 8. The downregulated ceRNA network in renal tissue. (A) Paired downregulated mRNA and corresponding circRNA and miRNA; the CeRNA network is composed of circRNA, miRNA and mRNA in renal tissue. The green node represents circRNA, the red node represents miRNA, and the blue node represents mRNA. (B) KEGG analysis of ceRNA pairing. (C) Screened network of key RNA nodes. Key nodes are represented by larger circles; the darker is the color, the greater is the number of related nodes.
