Ethanolic extracts of G. tenuistipitata (EEGT) induced activation of generic caspase in Ca9-22 oral cancer cells. (a) Cells treated with different concentrations (0 to 2.5 mg/mL) of EEGT for 24 h were stained with 1 μL 500X TF2-VAD-FMK. Positive % is indicated in each panel; (b) Quantificative analysis of pan-caspase fluorescent intensity. Data are presented as mean ± S.D. (n = 3). Differences between treatments of different concentrations containing the same capital letter at the top of each column are not significant.
