Additional file 3: of Celastrol mediates autophagy and apoptosis via the ROS/JNK and Akt/mTOR signaling pathways in glioma cells

Figure S3. Apoptotic nuclear morphological changes were evaluated by Hoechst 33342 staining and observed under a fluorescence microscope. The proportion of apoptotic cells was quantified. Red arrows indicate chromatin condensation and nuclear fragmentation. Scale bars = 100 μm. Data are presented as the Mean ± SD (n = 3). **P < 0.01, ***P < 0.001, significantly different compared with the untreated control group. (DOCX 820 kb
