Fig. 5. — Effects of X-ray or carbon ion radiation on the expression levels of Bax, Bcl-2, the PI3K/Akt/mTOR signalling path way and cyclin B1 in MDA-MB-231 and MCF-7 cells. The blots show the expression levels of the cell apoptosis-related proteins Bax and Bcl-2, the expression levels and phosphorylation level of the Akt/mTOR/p70S6K signalling pathway, and cyclin B1 in MDA-MB-231 (A, C) and MCF-7 (B, D) cells measured by western blotting assay 48 h after X-ray or carbon ion radiation at doses of 0, 2, 4 and 8 Gy. The bar graphs show the ratio of p-Akt/Akt, p-mTOR/mTOR and p-p70S6K/p70S6K in MDA-MB-231 (E) and MCF-7 (F) cells. β-Actin was used as the internal control. Data are the mean ± SD of three independent experiments. ^*P < 0.05, ^**P < 0.01 and ^***P < 0.001 by one-way ANOVA.
