Abstract
Friend spleen focus-forming virus shuts down its gene expression frequently (ca. 10(-3) per generation) in a cis-dominant hereditable fashion in various murine cells but much less frequently in rat cells (less than 10(-6) per generation). Thus, nonexpresser variants were isolated at high frequency from murine cell lines by immunoselection directed against virus-encoded cell surface glycoproteins and also simply by subcloning cells from lines which had been cultured for many generations. Studies of independently infected cell clones indicate that shutdown is a property of the cell line rather than of the specific proviral site. Nucleic acid blot analyses suggest that shutdown correlates with decreased transcription. Moreover, preliminary evidence indicates that other murine retroviruses also shut down frequently in murine but not in rat cells and that shutdown of replication-competent murine leukemia viruses with accompanying loss in interference to superinfection may be the rate-limiting reaction enabling cells to acquire multiple proviruses in their chromosomes. High-frequency shutdown in vivo would have important pathological consequences.
