Similar to the results in TCGA datasets, the expression levels of CXCL5/8/9/10/13/14/16 were significantly elevated in pancreatic cancer tissues, while the expression levels of CXCL2/4/7/12 were significantly reduced in tumor tissues, and there was no noticeable discrepancy in the expression of CXCL1/3/6/11/17 between the pancreatic cancer tissues and the normal pancreatic tissues (Figure 13). Here, CXCL5 is linked to neoplasm.
