Fig. 1From: Identification of candidate genes or microRNAs associated with the lymph node metastasis of SCLCThe heatmap and volcano plot of DEGs. a The heatmap of DEGs. Green colour corresponds to lowest and red to the highest level of gene expression. By unsupervised clustering, the samples all correctly segregate themselves. b Volcano plots for all the genes. The green dots indicate that up- and down-regulated DEGs were significant at p values less than 0.05Back to article page
