Abstract:
:Closed circular unintegrated DNA of the SEATO strain of gibbon ape leukemia virus (GaLV-S) was isolated from canine thymus fibroblasts after cocultivation with chronically infected bat lung fibroblasts. Restriction endonuclease HindIII cleaves GaLV-S DNA once, thus allowing isolation and cloning of HindIII-digested unintegrated DNA in a permitted form. Two clones isolated in the vector, Charon 21A, were nearly identical by restriction enzyme mapping to each of the two types of GaLV-S previously observed. These two types differ at a single SalI site. Unlike previous maps of GaLV-S proviral DNA, however, both clones lack SstI sites in the long-terminal-repeat units. Both the GaLV-S clones and the major species of GaLV-S proviral DNA contain an EcoRI site in the long-terminal-repeat units. The presence of this EcoRI site and the absence of an SstI site in the GaLV-S long-terminal-repeat units differentiate it from all other known GaLV strains and from the closely related nononcogenic simian sarcoma-associated virus. Heteroduplex comparisons of each of the two clones to clones of simian sarcoma-associated virus show no obvious deletion or substitution loops. This suggests that the ability of GaLV-S to induce myeloid leukemia in gibbon apes in not due to an acquired onc gene.
