Poly(ADP-ribosyl)ation studies in situ. 1986

D M Duhl, and L S Hnilica

We have studied the poly(ADP-ribosyl)ation of nuclear proteins in situ by examining the incorporation of [3H]NAD-derived ADP-ribose into polymers. We have devised a way to deliver [3H]NAD to cells growing in vitro, and we have determined the kinetics of uptake and incorporation into nuclear proteins using this delivery system. Incorporation into the histone fraction, known acceptors of poly(ADP-ribose), was examined and shown to be sensitive to the poly(ADP-ribose) polymerase inhibitor 3-aminobenzamide. Polyacrylamide gel electrophoresis of 3H-labeled proteins revealed radioactivity associated with known poly(ADP-ribose)-accepting proteins such as poly(ADP-ribose) polymerase and histones. These results were confirmed when we immunoreacted gel-separated proteins with anti-(ADP-ribose) generated in our laboratory.

D004247	DNA	A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).
