10779545 Werz O, Klemm J, Samuelsson B, Radmark O: 5-lipoxygenase is phosphorylated by p38 kinase-dependent MAPKAP kinases. Proc Natl Acad Sci U S A. 2000 May 9;97(10):5261-6.

When polymorphonuclear leukocytes were incubated with sodium arsenite (strong activator of 5-LO kinases), platelet-activating factor and exogenous AA, there was a 4-fold increase in 5-LO activity as compared with incubations with only platelet-activating factor and AA.

This study showed that various forms of cell stress, such as chemical stress (sodium arsenite), osmotic stress, or heat shock lead to substantial formation of 5-LO products in freshly isolated human polymorphonuclear leukocytes (PMNLs), when exogenous arachidonic acid (10 microM) was present.

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.

Our results reveal a significant increase in the degree of atherosclerotic plaque stenosis within the innominate artery of ApoE-/-/LDLr-/- mice treated with 10 ppm sodium arsenite (133 microM) in drinking water for 18 weeks compared to controls.
In addition, there is a significant increase in the 5-lipoxygenase (5-LO) product, leukotriene E4 (LTE4), in the serum of arsenic-treated mice.
