While Cxcl10 ascites concentrations were not affected by Cxcl9 overexpression in Brca2−/− tumour-bearing mice (median 38.6 vs. 23.8 pg/mg total protein; P = 0.23; Fig. 3c), they were more than fivefold higher in Brca2−/− than in BrcaWT tumour-bearing mice (median 8.2 vs. 45.5 pg/mg total protein; P = 0.0002; Fig. 3d). This evidence concerns the gene CXCL9 and neoplasm.
