1 We also found that arsenite-induced phosphorylation of extracellular signal-regulated kinases (ERK) or c-Jun NH(2)-terminal kinases (JNK) was markedly suppressed by Tpl2 kinase inhibitor or Tpl2 short hairpin RNA. arsenite mitogen-activated protein kinase 8 Homo sapiens
2 We also found that arsenite-induced phosphorylation of extracellular signal-regulated kinases (ERK) or c-Jun NH(2)-terminal kinases (JNK) was markedly suppressed by Tpl2 kinase inhibitor or Tpl2 short hairpin RNA. arsenite mitogen-activated protein kinase 8 Homo sapiens
3 Inhibition of arsenite-induced ERK or JNK signaling using a pharmacologic inhibitor of ERK or JNK substantially blocked COX-2 expression. arsenite mitogen-activated protein kinase 8 Homo sapiens
4 Inhibition of arsenite-induced ERK or JNK signaling using a pharmacologic inhibitor of ERK or JNK substantially blocked COX-2 expression. arsenite mitogen-activated protein kinase 8 Homo sapiens
5 Our results show that Tpl2 plays a key role in arsenite-induced COX-2 expression and PGE(2) production and further elucidate the role of Tpl2 in arsenite signals that activate ERK/JNK and NF-kappaB/AP-1 in JB6 P+ cells. arsenite mitogen-activated protein kinase 8 Homo sapiens
