Cytological detection of poly (ADP-ribose) polymerase

Experimental Cell Research, 1976
Abstract An attempt was made to demonstrate poly (ADP-ribose) polymerase cytologically. In vitro incorporation from the nucleotide, [ 3 H]NAD was detected in frozen sections of onion embryo and meristematic tissue by autoradiography. In meristematic tissue, there was a correlation between the number of cells displaying intensein vitro incorporation ...

Poly(ADP-ribose) polymerases: managing genome stability

The International Journal of Biochemistry & Cell Biology, 2005
The importance of poly(ADP-ribose) metabolism in the maintenance of genomic integrity following genotoxic stress has long been firmly established. Poly(ADP-ribose) polymerase-1 (PARP-1) and its catabolic counterpart, poly(ADP-ribose) glycohydrolase (PARG) play major roles in the modulation of cell responses to genotoxic stress.

Interaction of poly(ADP-ribose)polymerase with DNA polymerase ?

Molecular and Cellular Biochemistry, 1994
Homogeneously purified poly(ADP-ribose) polymerase (PARP) specifically stimulated the activity of immunoaffinity-purified calf or human DNA polymerase alpha by about 6 to 60-fold. Apparently, poly(ADP-ribosyl)ation of DNA polymerase alpha was not necessary for the stimulation.

Activity Assays for Poly-ADP Ribose Polymerase

2004
Poly(ADP-ribose) polymerase (PARP-1) is a nuclear enzyme that has traditionally been thought to require discontinuous or "damaged" DNA (dcDNA) as a coenzyme, a preconception that has limited research mainly to its role in cell pathology, i.e., DNA repair and apoptosis.

Detection of poly(ADP-ribose) polymerase and its reaction product poly(ADP-ribose) by immunocytochemistry

The Histochemical Journal, 1996
Poly(ADP-ribose) polymerase catalyses the formation of ADP-ribose polymers covalently attached to various nuclear proteins, using NAD+ as substrate. The activity of this enzyme is strongly stimulated upon binding to DNA single or double strand breaks. Poly(ADP-ribosyl)ation is an immediate cellular response to DNA damage and is thought to be involved ...

Poly(ADP-ribose) polymerase and aging

2001
Publisher Summary Poly(ADP-ribose) polymerase (PARP) is a major nuclear protein associated with chromatin that contains zinc fingers and binds to either double- or single-strand DNA breaks. Upon binding to DNA, PARP is activated and forms covalent homopolymers of poly(ADP-ribose) (PAR) attached to a number of nuclear proteins, including itself and ...

Inhibition of poly(ADP-ribose) polymerase in cancer

Current Opinion in Pharmacology, 2006
Inhibition of the DNA repair enzyme poly(ADP-ribose) polymerase-1 (PARP-1) has been extensively investigated in the pre-clinical setting as a strategy for chemo- or radio-potentiation. Recent evidence has suggested that PARP inhibitors might be active as single agents in certain rare inherited cancers that carry DNA repair defects.
