tokens: To examine the molecular basis of constitutive NF-kappaB DNA-binding activity in HIV1 -infected cells , we analyzed the phosphorylation and turnover of IkappaBalpha protein , the activity of the double-stranded RNA-dependent protein kinase ( PKR ) and the intracellular levels of NF-kappaB subunits in the PLB-985 and U937 myeloid cell models .
