a. Jurkat cells were treated with 25 uM Camptothecin for 6 hours with or without 1 hour pretreatment with 2 nM PGE2. Caspase-3/7 activity was assayed using a fluorescent substrate as described in Methods. Activity is expressed as Relative Fluorescence Units (RFLU). Data represent the mean ± standard error of 5 experiments in triplicate. B. Cells were treated as above and harvested after 12 hours, stained with propidium iodide for FACS analysis of apoptosis as described in Methods. Data are from representative experiment, N=3.
