PG - 1372-7 AB - To elucidate the regulation of IL-27p28 gene, we analyzed the promoter region of the gene in DC2.4 cells with or without lipopolysaccharide (LPS)-treatment. The results indicate that a region (-648 to -364) of p28 promoter was responsible for LPS-induction. EMSA with DNA probes within the region reveals that binding of GATA motif bound proteins was decreased by LPS-treatment. We identified one of the proteins as non-POU domain-containing octamer binding protein (NonO). Taken together, LPS-induced activation of IL-27p28 gene can be accounted for by the displacement of bound NonO protein from the IL-27p28 promoter.
