Identification of differentially expressed lncRNA in pancreatic cancer tissues.

LncRNA expression profiles were obtained from pancreatic tumor and non-tumor tissues derived from three patients via microarray. All analyzed lncRNAs were plotted in part (a). Twenty-six downregulated and 10 upregulated lncRNAs (fold change ≥ 2 and P value < 0.05) were further analyzed with unsupervised hierarchical clustering, and presented in a heat map (b).
