Figure 4. ceRNA sub-network of specific lncRNAs expressed only in keloid-prone individuals and qPCR verification of DElncRNAs in keloid and normal fibroblasts. (A) Sub-network of DLEU2. (B) Sub-network of AP000317.2. (C) Sub-network of downregulated lncRNAs. Green indicates downregulated molecules, red indicates upregulated molecules, diamonds indicate lncRNAs, circles indicate miRNAs, and squares indicate mRNAs. (D) qPCR verification of DElncRNAs in keloid and normal fibroblasts. *p<0.05.
