  • Title: Requirement of the human chromosome 11 long arm for replication of herpes simplex virus type 1 in nonpermissive Chinese hamster x human diploid fibroblast hybrids.
    Author: Francke U, Francke B.
    Journal: Somatic Cell Genet; 1981 Mar; 7(2):171-91. PubMed ID: 6270835.
    Abstract:
    Somatic cell hybrids between Chinese hamster (CH) lung cells (V79/380-6), nonpermissive for productive infection by herpes simplex type 1 (HSV-1), and permissive human diploid cells support productive HSV-1 infection as long as they retain human chromosome 11. Human chromosome 3 has been reported to complement nonpermissivity in (CH) Don cells (1). Intraspecies hybrids between Don/a3 and V79/380-6 cells, however, did not support HSV-1 replication, indicating lack of complementation. The block in both nonpermissive CH cell lines was determined to involve a step beyond replication of the parental viral DNA. In cell hybrids between nonpermissive Don/a23 cells and human fibroblasts containing a t(11;15) (p11;p12) translocation, HSV-1 production was dependent solely on the presence of either human chromosome 11 or the der(11) (p11 leads to qter) translocation product containing the long arm of chromosome 11. Chromosome 3 was excluded by a discordancy rate of 59%. We conclude that the long arm of human chromosome 11 carries one or more genes coding for host functions necessary for the production of progeny HSV-1 DNA.
