Description
| - Loss of programmed cell death pathways is one of the features of malignancy that complicate the response of cancer cells to therapy. Activation of alternative death pathways offers a promising approach to enhance efficiency of cancer chemotherapy. We analysed programmed cell death pathways of v-myb-transformed BM2 monobolasts induced by arsenic trioxide, cycloheximide and camptothecin. We show that cell death is not executed by caspases but rather by alternative cell death pathways: camptothecin induces the lysosome-dependent cell death, arsenic trioxide induces autophagy, and most of cycloheximide-treated BM2 cells die by necrosis. The fact that alternative cell death pathways can be switched in cells with defects in activation and/or function of caspases suggests that understanding and targeting of these pathways could improve therapy on cancer cells suffering from defective apoptosis.
