Relative to untreated MDA-MB-231 tumor xenografts, the xenografts from mice treated with UTI, TAX, and UTI+TAX showed decreased expression of IL-6 (Figure 5, Figure 6), IL-8 (Figure 7, Figure 8), and TNF-α (Figure 9 Figure 10) proteins. This evidence concerns the gene IL6 and bacterial urinary tract infection.
