title: Rapid inactivation of Ca2+, Mg2+-dependent endonuclease of rat liver nuclei after cycloheximide treatment.
abstract: Ca2+, Mg2+ dependent endonuclease activity of isolated nuclei from rat liver disappeared completely within one to two hours after intraperitoneal administration of inhibitors of eukaryotic protein synthesis such as cycloheximide or puromycin. Actinomycin D, on the other hand, revealed no inhibition of the endonuclease activity, but even reversed the effect of cycloheximide by simultaneous addition.
