title: Cytokine action and oxidative stress response in differentiated neuroblastoma SH-SY5Y cells.
abstract: In the retinoic acid-differentiated neuroblastoma SH-SY5Y cells, IL-1 induced binding activity of NFkappaB and up-regulated the expression and activity of MnSOD. The IL-1-elicited effects were partly reversed by IL-4 and IL-6. It is proposed that IL-4 and IL-6 may participate in the regulation of the imbalanced oxidant status induced by IL-1 in differentiated neuroblastoma cells. In the SH-SY5Y cell line, TNFalpha neither activated NFkappaB nor induced MnSOD expression and activity, but was capable of modulating the IL-1 effects. Pyrrolidine dithiocarbamate (PDTC), an inhibitor of NFkappaB activation, down-regulated the expression and activity of MnSOD, which may suggest that the regulation of MnSOD by IL-1 in retinoic acid-differentiated neuroblastoma cells was mediated by the nuclear factor kappaB.
