RNA synthesis and number of transcribing polymerase molecules in ischemic liver nuclei.
Nuclei isolated from ischemic liver show a consistent reduction of their RNA synthesis. The reduction persists at high ionic strength and in the presence of heparin, when RNA synthesis in vitro is fully activated and occurs in the presence as well as in the absence of alpha-amanitin. Both the number of transcribing polymerase molecules and the rate of elongation of initiated polynucleotide chains seem to be equally affected.
