IL6 and breast cancer: Surprisingly, when BC cells were challenged by Amy-F before RT a remarkable suppression in TGF-β protein expression (56.6%) was accompanied by a much more reduction in VEGF, INF-γ, IL-2, and IL-6 levels by 60.6, 60.2, 74.1 and 68.5%, respectively, was observed in MCF-7 cells, whereas a comparable impact was detected in MDA-MB-231 cells as indicated by reduced TGF-β expression (49.3%) as well as a significant decrease in VEGF, INF-γ, IL-2, and IL-6 levels by 66.3, 61.9, 83.3 and 75.6%, respectively, compared to control.
