These experiments clearly demonstrate that caspase inhibitors can be remarkably effective at attenuating the toxicological consequences of caspase activation and caspase inhibition can apparently rescue cells that are committed to die. FMK can block non-receptor mediated apoptosis but does not confer clonogenic viability. FMK may act downstream of the commitment point so that cells can still die but by a slower non-apoptotic form of cell death (Ashkenazi and Dixit, 1998).
