  • Title: Turnover of ribosomal 28S and 18S rRNA during rat liver regeneration.
    Author: Nikolov EN, Dabeva MD.
    Journal: Biosci Rep; 1983 Aug; 3(8):781-8. PubMed ID: 6626711.
    Abstract:
    The turnover of 28S and 18S rRNA was studied in the course of 12 d after partial hepatectomy, including the proliferative (1st to 5th d) and post-proliferative (6th to 12th d) phases of liver regeneration. Turnover data, as the day-to-day rates of synthesis and degradation of 28S and 18S rRNA, were obtained by employing a suitable experimental procedure for the estimation of the increase of the amount of rRNA in the regenerating liver. It was found that 28S and 18S rRNA are accumulated into the cytoplasm and degraded at identical rates both in the proliferative and post-proliferative phases. The turnover of both rRNA moieties is markedly slower during the first 3 d of liver regeneration.
