Induction of apoptosis and changes in calpain and COX-2 activities by TNF-α and their attenuation by calpain inhibitor. Cells were treated with TNF-α (100 ng/ml) for 24 hr. Calpeptin (1 and 5 μM) was added 5 min after the TNF-α addition. (A) Photomicrographs showing representative cells from each treatment following ApopTag assay. The arrows indicate apoptotic cells. (B) Determination of apoptosis based on ApopTag assay and percent changes in calpain and COX-2 activities (n = 3).
