LncRNA microarray analysis in papillary thyroid cancer (PTC) tissues compared with matched adjacent noncancerous thyroid tissues. a Hierarchical clustering analysis of differentially expressed lncRNAs. Red and green colors indicate high and low expression, respectively. In the heat map, columns represent samples and rows represent each lncRNA. b Volcano plot of differentially expressed lncRNAs between PTC and paired noncancerous thyroid tissue. The vertical lines correspond to 2.0-fold upregulation and downregulation, and the horizontal line represents a P value of 0.05
