FIGURE 3.
Characterization of caspases in 24S-OHC-treated SH-SY5Y cells. The cells were treated with 24S-OHC or STS for the indicated times, and the cell samples were then subjected to the enzyme assay (A) using DEVD-AMC (panel 1) or LEHD-AMC (panel 2) as a substrate and Western blot analysis (B) using an antibody against caspase-3 (panel 1) or caspase-9 (panel 2). **, p < 0.01, when compared with vehicle control (without 24S-OHC).
