Figure 4. Maf1 knockdown mitigates rapamycin inhibition of mitochondrial function in response to IR in A549 cells. (A, B) Mitochondrial membrane potential was evaluated by JC-1 staining followed by flow cytometry. Representative results are shown in (A) and the quantifications of 2 biological replicates are shown in (B). (C, D) Intracellular ROS levels were detected by H2DCFCA probes, followed by flow cytometry. Representative results are shown in (C) and the quantifications of 2 biological replicates are shown in (D). For all bar graph, the error bars stand for Standard Deviation (SD) of the mean. Statistical significance was evaluated by 2-tailed, paired student’s t-test (ns, not significant, *, P<0.05).
