Studies from L. Mondragon and colleagues reveal new findings on apoptosis
March 31st, 2009
According to recent research published in the journal Apoptosis, "QM31 represents a new class of cytoprotective agents that inhibit the formation of the apoptosome, the caspase activation complex composed by Apaf-1, cytochrome c, dATP and caspase-9. Here, we analyzed the cellular effects of QM31, as compared to the prototypic caspase inhibitor Z-VAD-fmk." "QM31 was as efficient as Z-VAD-fmk in suppressing caspase-3 activation, and conferred a similar cytoprotective effect. In contrast to Z-VAD-fmk, QM31 inhibited the release of cytochrome c from mitochondria, an unforeseen property that may contribute to its pronounced cytoprotective activity. Moreover, QM31...
