There was an up-regulated gene enrichment by BC in both GO: MF chemokine activity (GO:0008009) and GO: MF CXCR chemokine receptor binding (GO:0045236), sharing the same genes: CXCL1, CXCL3, CXCL5, CXCL6, CXCL8, and PF4V1 from 6:50 genes and 6:18 genes, respectively. This evidence concerns the gene CXCL6 and breast cancer.
