Last, interrogation of The Cancer Genome Atlas (TCGA) pancreatic adenocarcinoma (PAAD) cohort showed that both CCR1, the cognate receptor for Ccl9, and CCL23, the human homolog of murine Ccl9 (33), correlated with a TAN gene signature (Supplemental Figure 11). This evidence concerns the gene CCL23 and pancreatic adenocarcinoma.
