ALTERATIONS OF ADP-RIBOSYLATION AND DNA-BREAKS IN AGING BRAIN CELLS
Neuronal and astroglial cells were prepared from whole brain of three month and 30-month- old rats for study of alterations in the nuclear poly ADP-ribosylation and DNA breaks with age. The relative purity of the cell preparations was confirmed by the determination of the neurofilament (low molecular weight) and glutamine synthetase content of the cells using ELISA. An increase (75%) in th...
متن کاملStimulation of choleragen enzymatic activities by GTP and two soluble proteins purified from bovine brain.
Choleragen (cholera toxin) activates adenylate cyclase by catalyzing ADP-ribosylation of Gs alpha, the stimulatory guanine nucleotide-binding protein. It was recently found (Tsai, S.-C., Noda, M., Adamik, R., Moss, J., and Vaughan, M. (1987) Proc. Natl. Acad. Sci. U. S. A. 84, 5139-5142) that a bovine brain membrane protein known as ADP-ribosylation factor or ARF, which enhances ADP-ribosylatio...
متن کاملReversible mono‐ADP‐ribosylation of DNA breaks
Adenosine diphosphate (ADP)-ribosylation is a chemical modification of macromolecules that plays an important role in regulation of quintessential biological processes such as DNA repair, transcription, chromatin remodelling, stress response, apoptosis, bacterial metabolism and many others. ADP-ribosylation is carried out by ADP-ribosyltransferase proteins, such as poly (ADP-ribose) polymerases...
متن کاملIntracellular Mono-ADP-Ribosylation in Signaling and Disease
A key process in the regulation of protein activities and thus cellular signaling pathways is the modification of proteins by post-translational mechanisms. Knowledge about the enzymes (writers and erasers) that attach and remove post-translational modifications, the targets that are modified and the functional consequences elicited by specific modifications, is crucial for understanding cell b...
متن کاملDifferential activation of the stimulatory and inhibitory guanine nucleotide-binding proteins by fluoroaluminate in cells and in membranes.
Fluoroaluminate had no effect on cAMP levels in cells but inhibited agonist-stimulated cAMP accumulation. In membranes, fluoroaluminate stimulated adenylate cyclase activity between 1 and 10 mM but not at higher concentrations, and it inhibited agonist-stimulated adenylate cyclase activity at concentrations greater than 1 mM. Fluoroaluminate is known to activate Gs and Gi, the guanine nucleotid...
