The selective ability of paraquat and rotenone to induce apoptosis in different cell lines correlates with their ability to activate c-Jun N-terminal protein kinase (JNK) and p38 mitogen-activated protein kinases.

The downstream signaling pathways that govern the production of IL-8 include NF-kappaB and p38 MAPK.
We found that exposure of RPE cells to H (2) O (2), paraquat, or A2E-mediated photooxidation resulted in increased expression and secretion of IL-8.

Application of the mitogen-activated protein kinase kinase inhibitor caused the constitutive induction of the sodCc1, trxh, and grx genes and the activation of CORE without methyl viologen treatment.

Cyclo (His-Pro) attenuated reactive oxygen species production, and prevented glutathione depletion caused by glutamate, rotenone, paraquat and beta-amyloid treatment.
Finally, pharmacological inhibition of p-38 MAPK partially prevented both cyclo (His-Pro)-mediated Nrf2 activation and cellular protection.

Mitogen-activated protein kinase (MAPK) cascades function in biotic and abiotic stress responses in plants.
In leaves, ATMPK6 was activated by paraquat and 3-amino-1,2,4-triazole (a catalase inhibitor).

Bcl-xFNK might gain a new function to activate the mitogen-activated protein kinase in a cell-type specific manner.
When overexpressed in Jurkat cells, Bcl-xFNK was markedly more potent in prolonging survival following apoptosis-inducing treatment with a kind of cell death cytokines (anti-Fas), a protein kinase inhibitor (staurosporine), cell cycle inhibitors (TN-16, camptothecin, hydroxyurea, and trichostatin A), or oxidative stress (hydrogen peroxide and paraquat) than wild-type Bcl-x (L).

We also learned that the MAPK kinases MEK-1 and SEK-1, and the p53 antagonist protein ABL-1, are essential for stress-induced germ cell apoptosis.

16919916 Mitra S, Abraham E: Participation of superoxide in neutrophil activation and cytokine production. Biochim Biophys Acta. 2006 Aug;1762(8):732-41. Epub 2006 Jul 8.

These results demonstrate that increased intracellular superoxide concentrations are proinflammatory in neutrophils, acting through a p38 MAPK dependent mechanism that results in enhanced nuclear accumulation of NF-kappaB and increased expression of NF-kappaB dependent proinflammatory cytokines.
To examine the role of superoxide in neutrophil activation, we exposed resting neutrophils and neutrophils stimulated with LPS to paraquat, an agent that specifically increases intracellular superoxide concentrations.
