  • Title: POLIOVIRUS: GROWTH IN NON-NUCLEATE CYTOPLASM.
    Author: CROCKER TT, PFENDT E, SPENDLOVE R.
    Journal: Science; 1964 Jul 24; 145(3630):401-3. PubMed ID: 14172604.
    Abstract:
    Cytoplasmic fragments were produced by micromanipulation of cells from a human amnion cell line cultured on coverslips. The cultures were infected with type 1 (Mahoney) poliovirus, and incubated for 7 hours with tritiated uridine (H3U). Fluorescent antibody to the poliovirus indicated antigenic sites in a number of non-nucleate fragments. By autoradiography the incorporation of H3U was demonstrated at some of the same sites. The occurrence of poliovirus antigen at the same site as induced synthesis of RNA in non-nucleate cytoplasm of mammalian cells indicates that poliovirus infection and growth occurred independently of immediate contribution from the nucleus.
