8902523 Liu Y, Guyton KZ, Gorospe M, Xu Q, Lee JC, Holbrook NJ: Differential activation of ERK, JNK/SAPK and P38/CSBP/RK map kinase family members during the cellular response to arsenite. Free Radic Biol Med. 1996;21(6):771-81.

Exposure of cells to either proliferative or stressful stimuli elicits a complex response involving one or more distinct phosphorylation cascades culminating in the activation of multiple members of the mitogen-activated protein kinase (MAPK) family, including extracellular signal regulated kinase (ERK), stress-activated c-Jun N-terminal kinase (JNK/SAPK), and p38/RK/CSBP protein kinase.
In the present study, we examined ERK, JNK/SAPK, and p38 activation in cells treated with the sulfhydryl-reactive agent sodium arsenite.

Here we describe that activation of p38 mitogen-activated protein kinase in human polymorphonuclear leukocytes and in Mono Mac 6 cells leads to activation of downstream kinases, which can subsequently phosphorylate 5-LO in vitro.
Different agents activated the 5-LO kinase activities, including stimuli for cellular leukotriene biosynthesis (A23187, thapsigargin, N-formyl-leucyl-phenylalanine), compounds that up-regulate the capacity for leukotriene biosynthesis (phorbol 12-myristate 13-acetate, tumor necrosis factor alpha, granulocyte/macrophage colony-stimulating factor), and well known p38 stimuli as sodium arsenite and sorbitol.

Here, we report that the expression of mitogen-activated protein (MAP) kinase/extracellular signal-regulated kinase kinase kinase 1 (MEKK1), transforming growth factor-beta-activated kinase (TAK1), and apoptosis signal-regulating kinase (ASK1) in HepG2 cells activated the ARE reporter gene, whereas the expression of their dominant-negative mutants impaired ARE activation by the chemicals sodium arsenite and mercury chloride.

In the present study, the protective effect of melatonin on sodium arsenite (arsenite)-induced apoptosis was investigated.
Furthermore, melatonin attenuated arsenite-induced increases in heat shock protein 70 and heme oxygenase-1 as well as phosphorylation of p38 mitogen-activated protein kinase and elevations in cyclooxygenase II and inducible nitric oxide synthase expression.

We demonstrate that p38beta mitogen-activated protein (MAP) kinase augments ATF-2 transactivation activity on the PEPCK-C promoter, which is consistent with the interpretation that PEPCK-C promoter activity is maintained under stress through a p38 MAP kinase dependent pathway.
In this regard, we show that treatment with sodium arsenite, a known activator of p38 MAP kinases, also stimulates expression from the PEPCK promoter.

Eur J Biochem. 1995 Jan 15;227(1-2):416-27.

The kinase activity in extracts of cells stimulated by heat shock, H2O2, sodium arsenite, TNF or growth factors was identified by in-gel renaturation and purified approximately 8000-fold by sequential chromatography.
In all cases, the induced kinase activity was entirely associated with two polypeptides of 45 kDa and 54 kDa, identified as mitogen-activated-protein kinase-activated protein (MAPKAP) kinase-2 based on its reactivation in vitro by 42/44-kDa MAP kinases, its antigenic properties and its substrate specificity.

Phosphorylation of Ago2 at serine-387 was significantly induced by treatment with sodium arsenite or anisomycin, and arsenite-induced phosphorylation was inhibited by a p38 MAPK (mitogen-activated protein kinase) inhibitor, but not by inhibitors of JNK (c-Jun N-terminal kinase) or MEK [MAPK/ERK (extracellular-signal-regulated kinase) kinase].
Finally, mutation of serine-387 to an alanine residue or treatment of cells with a p38 MAPK inhibitor reduced the localization of Ago2 to processing bodies.

The stress-activated c-Jun N-terminal protein kinase (JNK) and p38 mitogen-activated protein (MAP) kinase (p38) regulate apoptosis induced by several forms of cellular insults.
Here we report evidence that sodium arsenite-induced apoptosis in PC12 cells may be due to direct phosphorylation of Bim (EL) at Ser-65 by p38.

In this study, we sought to explore the signaling pathway triggered by sodium arsenite and its implication for endothelial phenotype.

We have previously shown that osmotic stress activates both the mitogen-activated protein kinase (MAPK) cascade and the stress-activated protein kinase (SAPK, also known as JNK) cascade in rat fibroblastic 3Y1 cells and rat PC12 cells.
Here, we show that treatment of these cells with sodium arsenite, a chemical compound that mimics the effects of heat shock, or anisomycin, a protein synthesis inhibitor, induces activation of SAPKs potently.

Here we demonstrate that several stimuli of cell stress such as osmotic shock (sorbitol, NaCl), oxidative stress (hydrogen peroxide, diamide), chemical stress sodium arsenite, and inflammatory cytokines enhanced cellular 5-LO activity in a B cell line (BL41-E95-A), when added simultaneously with ionophore plus arachidonate.
These stimuli also activated p38 mitogen-activated protein (MAP) kinase and downstream MAP kinase-activated protein kinases in BL41-E95-A cells, which could phosphorylate 5-LO or heat shock protein 27 in vitro.
