We found that leukemic cells from ATL patients , like HTLV-I -infected T-cell lines , display constitutive NF-kappaB DNA binding activity and increased degradation of IkappaBalpha (an inhibitor of NF-kappaB ).
 ( protein: NF-kappaB, None) , ( cell line: HTLV-I -infected T-cell lines, None) , ( cell type: leukemic cells, None) , ( protein: NF-kappaB, None) , ( protein: IkappaBalpha, None)
