Using gene expression array data from the Expression Project for Oncology database (E-GEOD-2109), we observed strikingly low expression of CXCL9 and CXCL10 in human PDAC compared to other cancer types (Figure 2C), possibly indicating escape from anti- tumor surveillance by downregulation of chemokines that would normally recruit NK and T cells. Here, CXCL10 is linked to neoplasm.
