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, None) , ( protein: bcl-xl, None) , ( protein: Tax, None) , ( protein: bax, None) , ( protein: bcl-2, None) , ( cell line: CTLL-2 cells, None) , ( protein: bad, None) , ( protein: bcl-xs, None) , ( protein: bak, None)
