Role of NF-kappaB and AP-1 on Helicobater pylori-induced IL-8 expression in AGS cells.
Chu SH, Kim H, Seo JY, Lim JW, Mukaida N, Kim KH. Chu SH, et al. Dig Dis Sci. 2003 Feb;48(2):257-65. doi: 10.1023/a:1021963007225. Dig Dis Sci. 2003. PMID: 12643600
As a result, H. pylori induced the expression of mRNA and protein for IL-8 via activation of NF-kappaB and AP-1. NF-kappaB activation accompanied by a decrease in I-kappaBalpha and activated AP-1 complex was a c-jun/c-fos heterodimer in H. pylori-infected AGS cells. …
