Analyses of differentially expressed lncRNAs and their targets in the RNA-Seq libraries and qPCR. Twenty-four differentially expressed lncRNAs were selected from the EC, ICpEC and GE samples. Heat maps were constructed for (a) relative expression levels in qPCR (b) and log2 (FPKM) values in the RNA-Seq library. The colors ranging from red to green indicate high to low correlation. c Expression patterns of nine lncRNAs corresponding to the heat map and their potential target genes. DlRan3B was used as a reference gene to normalize lncRNA and mRNA expression data
