Effects of overexpression of Bcl-2 in Jurkat cells on their susceptibility to tumor-mediated DNA degradation.
Bcl-2 or control Neo-transfected Jurkat cells were labeled with [3H]TdR and coincubated with tumor cells at a tumor-to-lymphocyte cell ratio of 40:1. As controls, these cells were treated with agonistic anti-Fas Ab (CH-11, 200 ng/mL) or VP-16 (20 μmol/L). Target cell apoptosis was determined at the indicated time points by measuring loss in 3H-labeled DNA in the JAM assay. The error bars represent the SEM of 8 replicates.
