[Autoradiographic study of RNA synthesis and secretion into the cytoplasm during the early stages of liver regeneration].
Autoradiographic experiments with regeneration of rat liver showed that RNA transport from nucleus to cytoplasm occurs more quickly in 3h following partial hepatectomy while the total RNA synthesis increases insignificantly. Nucleolar RNA synthesis at this time grows in some hepatocytes and decreases in others though it does not differ on the average from the control one. By the 6th h after partial hepatectomy total RNA synthesis significantly increases simultaneously with the acceleration of RNA transport to cytoplasm. Nucleolar RNA synthesis intensifies in all hepatocytes.
