Figure 7: Effects of Florin extracts on caspase-3, -8, and -9 activities in TCCSUP cells. After treatment with 25 μg/mL of Florin extracts for 12, 24, and 48 h, cell lysates were prepared and enzymatic activities of caspase-3, -8, and -9 were measured by colorimetric assay. The caspase-3, -8, and -9 activities in control cells were taken as 1-fold, and the relative changes of these activities in the treated cells were estimated (* , ** ).
