title: ADP-ribosyl-protein conjugate subclasses in various tissues. Specific influence of thyroid hormone on liver conjugates.
abstract: The amounts of endogenous mono (ADP ribose)-protein conjugates and their hydroxyl-amine-sensitive and hydroxylamine-resistant subfractions in various tissues of the mouse were determined and compared with poly (ADP-ribose) conjugates. Total mono-(ADP-ribose) conjugates did not correlate with poly (ADP-ribose) residues or the cellularity of a tissue, but were related to the protein content and the amounts of NAD+ +NADH. The hydroxylamine-resistant subfraction, which in liver is mainly associated with the mitochondria [Adamietz, Wielckens, Bredehorst, Lengyel & Hilz (1981) Biochem. Biophys. Res, Commun. 101, 96-103], did not correlate with the tissue content of cytochrome c oxidase. In hypothyroid mice hydroxylamine-resistant mono (ADP-ribose) conjugates of the liver were increased by a factor of two while the hydroxylamine-sensitive conjugates did not change significantly under these conditions. Upon administration of thyroxine the hydroxylamine-resistant subfraction returned to normal.
