The ability of ascorbate to enhance cytoplasmic inhibitory IkBalpha protein degradation correlates completely with its capacity to induce NF-kappaB binding to DNA and to potentiate NF-kappaB -mediated transactivation of the HIV-1 long terminal repeat promoter in TNF-alpha -stimulated Jurkat cells but not in cells stimulated with PMA plus ionomycin .
