Fig. 2From: Identification and potential mechanisms of a 4-lncRNA signature that predicts prognosis in patients with laryngeal cancera Heatmap of differentially expressed lncRNAs. We conducted gene expression profiling to identify lncRNAs that were differentially expressed between 111 tumor tissue samples and 12 normal tissue samples. b Volcano plot of differentially expressed lncRNAs. Each red dot represents an upregulated gene, and each green dot represents a downregulated geneBack to article page
