In this study, we demonstrate that constitutive expression of bcl-xl but not bcl-2 , bcl-xs , bak , bad , or bax was associated with apoptosis resistance after IL-2 deprivation in CTLL-2 cells that expressed Tax .
 protein: IL-2; protein: bcl-xl; protein: Tax; protein: bax; protein: bcl-2; cell line: CTLL-2 cells; protein: bad; protein: bcl-xs; protein: bak
