  • Title: [Representation of the leader region of Rous sarcoma virus genome RNA in double-stranded RNA produced in virus-transformed cells].
    Author: Perevozchikov AP, Sizonenko GI.
    Journal: Mol Biol (Mosk); 1987; 21(5):1179-85. PubMed ID: 2824985.
    Abstract:
    Restriction fragments of recombinant plasmids containing a proviral sequence of Rous sarcoma virus (RSV) were Southern hybridized with double-stranded (ds) RNA isolated from the cells transformed with RSV. Hybridization data show that the major subpopulation of dsRNA molecules is homologous to the 5'-end region of the viral genome including the leader sequence. We have analysed the RNAs of RSV-transformed cells by the Northern procedure hybridizing them with the proviral fragment containing double long terminal repeats. The results demonstrate that the 14-16S RNA fraction is enriched in sequences which are homologous to the proviral end regions. We consider this RNA fraction to be homologous to the 5'-terminal region of the viral genome and (or) to its antisense strand.
