Analysis of the gene expression profile of 69 pancreatic tumor tissues and 61 adjacent nontumor tissues in the GSE62452 database, revealed that the expression of CXCL5 was significantly higher in pancreatic cancer tissues than in adjacent nontumor tissues (p<0.0001, Mann-Whitney U test, Fig. 1C). This evidence concerns the gene CXCL5 and pancreatic neoplasm.
