Figure 2: Bioinformatic analysis of gastric cancer secretome data.

(A) A volcano plot of gene expression analysis of 1,181 genes. Up-regulated and down-regulated genes are highlighted in red (51 genes) or blue circles (31 genes), respectively. (B) Gene ontology enrichment analysis of the cellular component of 51 up-regulated genes. (C) Cluster analysis among the six gastric cancer cell lines using 51 up-regulated genes. DGC and IGC cell lines are labeled with purple and orange, respectively.
