Here we show that deregulated expression of a single viral gene , ORF 50 , which encodes a transactivator able to selectively upregulate delayed-early viral genes , suffices to disrupt latency and induce the lytic gene cascade in latently infected B cells .
 ( cell type: latently infected B cells, None) , ( DNA: delayed-early viral genes, None) , ( DNA: ORF 50, None) , ( DNA: viral gene, None)
