The designation of the groups in Fig. 3 is incorrect. The white dot indicates “Hcy 100 μM,” and the black dot indicates “Control.” The correct figure appears on the following page. In addition, on page 586, in line 2, the figure reference should read “(Fig. 1C)” instead of “(Fig. 1A).”

Fig. 3. Homocysteine (Hcy) enhances the activity of caspase-9 and caspase-3 but not caspase-8. Activities of specific caspases were measured in HS-5 cells using commercially available assay kit (A–C). After treatment with or without 100 μM of Hcy for indicated times, the enzyme activity was measured as the fluorescence produced by cleavage of substrate by the respective caspase. (D) HS-5 cells were treated with 50 μM of caspase-8 inhibitor (Ac-DEVD-CHO) and caspase-9 inhibitor (LEHD-CHO) 2 h prior to Hcy 100 μM treatment. After 24 h of incubation, the cells were prepared to measure caspase-3 activity. All experiments were repeated three times of triplicate measurements. Shown are the mean (+SD) percentages of the untreated control levels at 0 h. *P < 0.01 vs. untreated control, †P < 0.01 vs. Ac-DEVDCHO-treated control.
