Abstract:

A technique of protein-DNA flow cytometry was applied to characterize cell cycling, and to assess the cytotoxicity of cladribine (2-chloro-2’deoxyadenosine) toward seven dissociated cultures of human primary brain tumors (anaplastic astrocytoma and glioblastoma multiforme) grown in vitro from surgical biopsies. Control cytograms were suggestive of that a clonogeneic fraction of the cell population consists mainly of cells with low protein content, which do not require increase in protein content before entering the S phase of the cell cycle. Following 24 or 48 hours exposure to cladribine, 1 nM -1 M, no cytotoxic effect was evident in 4 cultures, whereas in two cases dose-dependent progressive block of the phaseof the cell cycle was noted. In one case a massive cytotoxic effect resulted in disintegration of culture exposed to 100 nM ofthe drug. However, the treatment with cladribine was ineffective in a patient bearing the tumor which was the source forthe last culture, suggesting that cytotoxicity in vitro may not be predictive of clinical response.
