lncRNA GAS5 expression was downregulated in breast cancer cells and inhibited by IR. (a) Expression levels of lncRNA GAS5 in different breast cancer cell lines, including MCF-10A, MCF-7, and MDA-231. (b) Expression levels of lncRNA GAS5 in MCF-7 cells at different times (0, 4, 8, and 12 h) after 8 Gy irradiation. (c) Expression levels of lncRNA GAS5 in MCF-7 cells after 4 and 8 Gy irradiation at a dose rate of 1 Gy/min. ∗P < 0.05, ∗∗P < 0.01, and ∗∗∗P < 0.001 vs. the control group.
