In this study, we demonstrate that Tax -stimulated nuclear expression of NF-kappa B in both HTLV-I -infected and Tax -transfected human T cells is associated with the phosphorylation and rapid proteolytic degradation of I kappa B alpha .
 ( protein: Tax, None) , ( protein: Tax, None) , ( protein: NF-kappa B, None) , ( protein: I kappa B alpha, None) , ( cell line: HTLV-I -infected and Tax -transfected human T cells, None)
