Abstract:
:Retroviruses have been isolated from the tissues of human leukemia patients. Previous studies have shown that these isolates share some antigenic determinants with the family of viruses isolated from the woolly monkey and gibbon ape and that they exhibit partial nuclei acid homology with this same group of viruses. We have compared the RNAs of the viruses by two-dimensional polyacrylamide gel electrophoresis of the large RNase T1-resistant oligonucleotides. The degree of sequence identity between the RNAs was determined by the similarity of their RNase T1-resistant oligonucleotide pattern on gels, fingerprints, and in some cases by partial sequence analysis of individual oligonucleotides. This technique permits us to determine the degree of sequence identity among related RNA species. From our studies we conclude that viruses isolated from the tissues of two human leukemia patients, A1476 and SKA 21-3, as well as some subcultures of a virus isolated from the leukemic tissues of a third patient, HL23V, are closely related to the wooly monkey virus. However, the fingerprints of other HL23 viral isolates are very similar to that of GaLVSF, a gibbon ape leukemia virus isolated from a lymphosarcoma.
