The effect of FA pretreatment on IR-induced changes of Bax, Bcl-2, cleaved caspase-3, and procaspase-3 in HLECs. (a) Representative blots of Bax, Bcl-2, cleaved caspase-3, procaspase-3, and GAPDH. (b) Bar graphs of relative protein expression of Bax, Bcl-2, and caspase-3 in each group. HLECs were pretreated with FA (50, 100, and 200 μM) for 2 hours followed by exposure to 4 Gy X-ray radiation and then incubated for 72 h. All data were expressed as means ± SD. ^∗P < 0.05 vs. the control group; ^#P < 0.05 vs. the IR group.
