ceRNA network construction and protein–protein interaction network. (A) A lncRNA-miRNA-mRNA ceRNA network was constructed by 33 lncRNAs, 21 miRNAs, and 135 mRNAs. (B) A PPI network was constructed based on the STRING database. The rectangle represents microRNAs, the circle represents mRNAs and the triangle represents lncRNAs; the red represents up-regulation in IS-high and the green represents down-regulation in IS-high; the size of the dot represents the regulatory capacity of the mRNA, and larger points indicate stronger regulatory capability. ceRNA, competing endogenous RNAs; PPI: protein–protein interaction.
