1 When Jurkat T cells were treated with 1.25-5.0mM L-canavanine for 36 h, apoptotic cell death accompanying several biochemical events such as caspase-3 activation, degradation of poly(ADP-ribose) polymerase (PARP), and apoptotic DNA fragmentation was induced in a dose-dependent manner; however, cytochrome c release from mitochondria was not detected.

2 These results demonstrate that the cytotoxic effect of L-canavanine on Jurkat T cells is attributable to the induced apoptosis and that L-canavanine-induced apoptosis is mediated by a cytochrome c-independent caspase-3 activation pathway that can be interrupted by Bcl-2 or Bcl-xL.
