Furthermore, differentially transcriptional levels of CXC chemokines in the GEPIA2 online database consistently showed higher transcriptional levels of CXCL1, CXCL3, CXCL4, CXCL5, CXCL6, CXCL8, CXCL9, CXCL10, CXCL13, CXCL14, CXCL16, and CXCL17 in PAAD (all p < 0.01, Figure 2). The gene discussed is CXCL1; the disease is pancreatic adenocarcinoma.
