In the present study we investigated the possible involvement of the mitogen-activated protein kinase family members extracellular-regulated kinase 1/2 ( ERK1/2 ) and c- Jun N-terminal kinase ( JNK ) in mediating IL-6 gene expression in human monocytes , in particular their role in enhancing NF-kappa B activity .
 ( protein: ERK1/2, None) , ( protein: extracellular-regulated kinase 1/2, None) , ( protein: IL-6, None) , ( protein: JNK, None) , ( protein: Jun N-terminal kinase, None) , ( protein: NF-kappa B, None) , ( protein: mitogen-activated protein kinase family, None) , ( cell type: human monocytes, None)
