    Snippet: In a previous investigation (5) , we demonstrated that specific inhibitors for DNA topoisomerases I (camptothecin) and II (mAMSA and VM-26) prevent the CTL-induced DNA fragmentation of the target cell's DNA without impairing the disruption of the target cell's plasma membrane. DNA topoisomerases are cdl cycle-regulated enzymes with low to undetectable activity in early G1 and peak activity in the S and GO/M phases of the cell cycle (6) . We there.....
    Document: In a previous investigation (5) , we demonstrated that specific inhibitors for DNA topoisomerases I (camptothecin) and II (mAMSA and VM-26) prevent the CTL-induced DNA fragmentation of the target cell's DNA without impairing the disruption of the target cell's plasma membrane. DNA topoisomerases are cdl cycle-regulated enzymes with low to undetectable activity in early G1 and peak activity in the S and GO/M phases of the cell cycle (6) . We therefore, sought to determine whether the susceptibility of target cells to CTLinduced apoptosis was cdl cycle-related and show here that it is.
