Volcano plots (A, B) and heat maps (C, D) showing expression profiles of lncRNAs and mRNAs between diabetic and nondiabetic patients. A Volcano plot of the differentially expressed lncRNAs. Red points denote up-regulated mRNAs, and blue points denote down-regulated mRNAs. B Volcano plot of the differentially expressed mRNAs. C Heatmap depicting expression levels of the lncRNAs. The red stand for the up-regulated DEGs and the blue stand for down-regulated DEGs. D Heatmap depicting expression levels of the differentially expressed mRNAs
