Figure Lengend Snippet: Monitoring of apoptosis reporter in live cells. (A) HEK293 EGFP #4-8 cells were cultured with or without 1 μM STA, and images were obtained every 30 min for 48 h; scale bar 50 μm. Relative EGFP fluorescence intensity was measured using ImageJ software (N = 3). (B) Protein levels of GFP, caspase-3, cleaved caspase-3, cytochrome C , PARP, and GAPDH by Western blotting in HEK293 EGFP #4-8 cells incubated with STA. Graph, protein levels (N = 3). (C) HEK293 EGFP #4-8 cells were cultured with 1 μM STA co-treated with or without 20 μM Z-DEVD-FMK and 10 μM Z-YVAD-FMK, and images were obtained every 30 min for 48 h. Relative EGFP fluorescence intensity was measured using ImageJ software (N = 3). (D) HEK293 EGFP #4-8 cells were cultured with 100, 200, and 500 μM H 2 O 2 , and images were obtained every 30 min for 24 h. Relative EGFP fluorescence intensity was measured using ImageJ software (N = 3). Error bars are ± SD. *P < 0.05. **P < 0.01. ***P < 0.001. ****P < 0.0001.
