Reports summarize apoptosis research from University of Quebec
January 20th, 2009
According to recent research from Laval, Canada, "Arsenic trioxide (ATO) is known for treating acute promyelocytic leukemia and for inducing apoptosis and mitogen-activated protein kinases (MAPKs) in promyelocytes and cancer cells. We recently reported that ATO induces neutrophil apoptosis." "The aim of this study was to establish whether or not ATO recruits MAPKs in neutrophils, as well as to further investigate its agonistic properties. We found that ATO activates p38 and that, unlike H2O2, this response was not inhibited by exogenous catalase. Also, we demonstrated that ATO-induced p38 activation occurs before H2O2 generation and without a calcium burst. We next...
