An ability of the Epstein-Barr virus latent membrane protein LMP1 to enhance the survival of infected B cells through upregulation of the bcl-2 oncogene was first suggested by experiments involving gene transfection and the selection of stable LMP1 + clones (S.Henderson, M. Rowe, C.Gregory, F.Wang, E.Kieff, and A.Rickinson, Cell 65:1107-1115, 1991).
