    Genetics 165:83-99. 2003
    ..Furthermore, a decrease in the synthesis of Ty1 cDNA is strongly associated with Ty1 CNC. Together our results suggest that Ty1 cosuppression can occur post-transcriptionally, either prior to or during reverse transcription...

    David J Garfinkel
    Gene Regulation and Chromosome Biology Laboratory, Center for Cancer Research, National Cancer Institute, Frederick, Maryland 21701 1201, USA
    Genetics 169:1845-57. 2005

    David J Garfinkel
    National Cancer Institute, P O Box B, Frederick, MD 21702 1201, USA
    J Virol 80:11920-34. 2006
