SB 203580 29-37 nuclear factor kappa B subunit 1 Homo sapiens 47-69 10960075-4 2000 In fact, 5 and 10 microM SB203580 enhanced rather than inhibited NF-kappaB-mediated promoter activity by 2 fold, which was independent of phosphorylation of the p65 subunit. SB 203580 25-33 nuclear factor kappa B subunit 1 Homo sapiens 65-74 10960075-5 2000 The SB203580-mediated increase in NF-kappaB transcriptional activity was associated with enhanced phosphorylation of extracellular signal-regulated kinase (ERK)1/2 and c-Jun N-terminal kinase (JNK), but not p38 kinase. SB 203580 4-12 nuclear factor kappa B subunit 1 Homo sapiens 34-43 10960075-6 2000 Overexpression of kinase-deficient mutants belonging to the ERK1/2, JNK, and p38 pathways showed that only dominant-negative Raf-1 abrogated SB203580-enhanced NF-kappaB activity. SB 203580 141-149 nuclear factor kappa B subunit 1 Homo sapiens 159-168 10960075-7 2000 This would implicate the involvement of the ERK1/2 pathway in the enhancing effects of SB203580 on NF-kappaB-mediated gene transcription. SB 203580 87-95 nuclear factor kappa B subunit 1 Homo sapiens 99-108 10960075-9 2000 SB203580 at higher concentrations activates the ERK pathway, which subsequently enhances NF-kappaB transcriptional activity. SB 203580 0-8 nuclear factor kappa B subunit 1 Homo sapiens 89-98
