Fig. 1From: Integrative analysis of gene expression profiles reveals specific signaling pathways associated with pancreatic duct adenocarcinomaGenes differentially expressed between pancreatic cancer tissues and normal tissues. We analyzed differentially expressed genes in six GEO microarray datasets. Up-regulated: the number of genes whose expression levels were higher in pancreatic cancer tissues than in normal tissues. Down-regulated: the number of genes whose expression levels were lower in pancreatic cancer tissues than in normal tissues.
