SNL results in the expression profiling changes of lncRNA and mRNA. Scatter plot comparing global lncRNA (a) or mRNA (b) gene expression profiles in the spinal cord between the SNL and sham mice. Green lines indicate twofold differences in either direction in lncRNA and mRNA expression. Heat map showing hierarchical clustering of overall lncRNAs (c) or mRNA (d) expression pattern of reliably measured probe sets. Heat map showing hierarchical clustering of LncRNAs (e) or mRNA (f), whose expression changes were more than twofold. In clustering analysis, up- and down-regulated genes are colored in red and green, respectively.
