As the results, the apoptosis was repressed by various PARP inhibitors especially by 3 - aminobenzamide ( 3 – ABA ), which is a potent inhibitor forPARP reaction. On the contrary, 3-ABA was no more inhibitory in a cell-free apoptosissystem. This result suggests that the inhibitory effect of 3 - ABA is effective only before apoptotic cytosol is made up in the cells, i.e., in an early stage of the apoptotic process. But NAD inhibited the apoptosis in the same system depending on NAD concentration. So the inhibition of apoptosis by NAD may be concerned in a later step of apoptosis.}, pages = {73--85}, title = {Effects of poly (ADP-ribose) polymerase inhibitors and NAD on the apoptosis induced by actinomycin D in human leukemia cells HL-60}, volume = {21}, year = {1999} }
