FIGURE5 The PPI network of mRNAs from ceRNA network. (A) The results of the STRING database showed the protein-protein interaction network. Yellow line, interactions form textmining; blue-green line, known interactions from curated databases; dark blue, predicted interactions form gene co-occurrence; black line, interactions form co-expression; purple line, known interactions from experimentally determined; light blue, interactions form protein homology. (B) Square shapes represent genes, and lines represent interaction relationships. PPI, protein-protein interaction; mRNAs, messenger RNAs; ceRNA, competing endogenous
