1 Treatment of macrophages with vanadate results in the activation of both NF-kappaB and c-Jun N-terminal kinase (JNK). Vanadates mitogen-activated protein kinase 8 Homo sapiens
2 Treatment of macrophages with vanadate results in the activation of both NF-kappaB and c-Jun N-terminal kinase (JNK). Vanadates mitogen-activated protein kinase 8 Homo sapiens
3 Conversely, blockage of JNK activation by transfection of a kinase-inactive form of SEK1 resulted in partially inhibition of vanadate-induced IkappaBalpha degradation. Vanadates mitogen-activated protein kinase 8 Homo sapiens
4 Both vanadate-induced degradation of IkappaBalpha and activation of JNK were potently inhibited by pretreatment of cells with N-acetylcysteine or dimercaprol. Vanadates mitogen-activated protein kinase 8 Homo sapiens
5 These results demonstrate that early activation of stress kinases or change of cellular redox states plays a key role in vanadate-induced activation of NF-kappaB and JNK. Vanadates mitogen-activated protein kinase 8 Homo sapiens
