1 In this study we identify a selective and potent antisense oligonucleotide to RhoA (ISIS 17131) and investigate its effect on JNK activation induced by IL-1beta and H2O2 in A549 cells. Hydrogen Peroxide mitogen-activated protein kinase 8 Homo sapiens
2 The RhoA antisense oligonucleotide was able to inhibit JNK activation when A549 cells were stimulated by H2O2, but did not have any effect on IL-1beta induced JNK activation. Oligonucleotides mitogen-activated protein kinase 8 Homo sapiens
3 The RhoA antisense oligonucleotide was able to inhibit JNK activation when A549 cells were stimulated by H2O2, but did not have any effect on IL-1beta induced JNK activation. Hydrogen Peroxide mitogen-activated protein kinase 8 Homo sapiens
4 Additionally, Wortmannin, a potent inhibitor of the PI 3-kinase and phospholipase A2 (PLA2), and AACOCF3, also a PLA2 inhibitor, were able to inhibit JNK activation induced by H2O2, but they had no effect on JNK activation when stimulated by IL-1beta. Wortmannin mitogen-activated protein kinase 8 Homo sapiens
5 Additionally, Wortmannin, a potent inhibitor of the PI 3-kinase and phospholipase A2 (PLA2), and AACOCF3, also a PLA2 inhibitor, were able to inhibit JNK activation induced by H2O2, but they had no effect on JNK activation when stimulated by IL-1beta. Wortmannin mitogen-activated protein kinase 8 Homo sapiens
6 Additionally, Wortmannin, a potent inhibitor of the PI 3-kinase and phospholipase A2 (PLA2), and AACOCF3, also a PLA2 inhibitor, were able to inhibit JNK activation induced by H2O2, but they had no effect on JNK activation when stimulated by IL-1beta. Hydrogen Peroxide mitogen-activated protein kinase 8 Homo sapiens
7 Additionally, Wortmannin, a potent inhibitor of the PI 3-kinase and phospholipase A2 (PLA2), and AACOCF3, also a PLA2 inhibitor, were able to inhibit JNK activation induced by H2O2, but they had no effect on JNK activation when stimulated by IL-1beta. Hydrogen Peroxide mitogen-activated protein kinase 8 Homo sapiens
8 These results suggest that, in A549, IL-1beta and H2O2 induce JNK activation by two independent pathways. Hydrogen Peroxide mitogen-activated protein kinase 8 Homo sapiens
