IHC analyses showed that compared with the control group, BA patients have significant higher expression levels of IL-33 (3.9 ± 0.5 vs. 1.0 ± 0.3, p = 0.0447, Figures 1A,B), TGF-β1 (3.3 ± 0.3 vs. 1.0 ± 0.2, p = 0.0071, Figures 1D,E), and IL-13 (3.6 ± 0.4 vs. 1.0 ± 0.3, p = 0.0270, Figures 1G,H). This evidence concerns the gene IL33 and breast angiosarcoma.
