To gain further insight into yeast acetic acid-induced programmed cell death (AA-PCD) we analyzed the effects of the antioxidant N-acetyl-l-cysteine (NAC) on cell viability, hydrogen peroxide (H(2)O(2)) production, DNA fragmentation, cytochrome c (cyt c) release and caspase-like activation in wild type (wt) and metacaspase and/or cyt c-lacking cells. We found that NAC prevents AA-PCD in wt cells, by scavenging H(2)O(2) and by inhibiting both cyt c release and caspase-like activation. This shows the occurrence of a reactive oxygen species (ROS)-dependent AA-PCD. Contrarily no NAC dependent change in AA-PCD of mutant cells was detectable, showing that a ROS-independent AA-PCD can also occur.CI - Copyright (c) 2010 Federation of European Biochemical Societies.
