Pink1/PARK2/mROS-Dependent Mitophagy Initiates the Sensitization of Cancer Cells to Radiation

Figure 1

Changes of autophagy, mROS content, and mitochondrial impairment in HeLa and MCF-7 cells. (a) After treatment with 8 Gy IR and NAC (1 mM), representative pictures of autophagy were measured with MDC staining by FCM. (b) Autophagic rates were analyzed by FCM. (c) Western blot analysis of LC3, GAPDH protein was used for loading control, and LC3II/LC3I was quantified. (d) ROS contents were detected by DCFH-DA staining (10 μM) and analyzed by FCM after 8 Gy IR and NAC (1 mM) treatment. (e) The mitochondrial mass was detected by MitoTracker Green (200 nM) staining. Scale bar, 50 μm. Bars represent of triplicate measurements. and , versus 0 Gy; #, versus control.
