tokens: 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 ) .
