3115798-1	1987	A selection strategy to obtain cells deficient in poly(ADP-ribose) polymerase was developed based on the fact that treatment with high levels of N-methyl-N"-nitro-N-nitrosoguanidine results in sufficient activation of poly(ADP-ribose) polymerase to cause NAD and ATP depletion leading to cessation of all energy-dependent processes and rapid cell death.	Nitrosoguanidines	165-181	poly(ADP-ribose) polymerase 1	Homo sapiens	50-77
