Chloroquine inhibits glioma cell growth and viability in culture. (A) Assessment of cell growth rates in glioma cells with known functional status of p53.³¹ Cells were treated with a range of chloroquine concentrations indicated in the legends. (B) Assessment of cell death rates in glioma cells lines with wtp53 (left panel) or deficient p53 function (middle and right panels). Values represent the mean of 6 replicates.
