Pulse cytophotometric analysis of cell cycle perturbation with bleomycin in vitro

B Barlogie et al. Cancer Res. 1976 Mar.

Abstract

The kinetic response of a human lymphoma cell line to bleomycin has been analyzed, using an ICP-11 pulse cytophotometer. Bleomycin induced a delay of the cell-cycle traverse in G2 phase, the extent and recovery of which depended on drug concentration, exposure time, and cell cycle stage where treatment was applied. Different phase sensitivity for lethal damage (G2 phase) and kinetic response (early S phase) were documented. Recovery from G2 block did not predict for unimpaired reproductive capacity.
