Hierarchical clustering analysis of gene expression levels between H.pylori-infected groups and control groups. 303 lncRNAs a and 565 mRNAs b were significantly changed in response to H.pylori infection. The clustering analysis was performed by Cluster 3.0 software with average linkage clustering algorithm and visualized by Treeview. “S” and “C” represent H.pylori-infected groups and control groups. “Red” and “green” indicate up-regulated and down-regulated transcripts, respectively
