  • Title: [Selective inhibition by chloramphenicol of protein biosynthesis in ascites tumor cells].
    Author: Bul'diaeva TV, Bazarnova TM, Kuz'mina SN, Zbarskiĭ IB.
    Journal: Eksp Onkol; 1984; 6(4):35-8. PubMed ID: 6499749.
    Abstract:
    Chloramphenicol in a dose of 50-200 micrograms/ml sharply inhibits the incorporation of 14C-labelled amino acids into proteins of ascites Zajdela hepatoma cells while it has no effect on protein biosynthesis in rat liver cells. In vivo chloramphenicol selectively inhibits this process in ascites tumour cells of rat Zajdela hepatoma and mouse Ehrlich carcinoma and hepatoma 22a, without inhibiting the process in various organs of tumour-bearing animals. The inhibition of labelled amino acid incorporation into nuclear and especially nuclear matrix proteins is more pronounced than into the whole tissue. A certain degree of inhibition was revealed in liver cells as well.
