title: [Induction of infectious Friend virus after treatment with 5-azacytidine of a non-virus-producing erythroleukemia line (HFL/b)].
abstract: A Friend virus induced erythroleukemia cell line (HFL/b cells) did not produce infectious MuLV and only expressed the defective SFFV component of Friend virus (SFFV (+), F-MuLV (-)). This line temporarily produced infectious F-MuLV following 5 azacytidine treatment. These results suggest that the F-MuLV expression is specifically repressed in these cells by a mechanism which does not affect the F-MuLV related SFFV genome.
