8702935 Sapirstein A, Spech RA, Witzgall R, Bonventre JV: Cytosolic phospholipase A2 (PLA2), but not secretory PLA2, potentiates hydrogen peroxide cytotoxicity in kidney epithelial cells. J Biol Chem. 1996 Aug 30;271(35):21505-13.

Phospholipase A2 (PLA2) and reactive oxygen species have been implicated both individually and synergistically in various forms of cellular injury.
Exposure to hydrogen peroxide or menadione, but not mercuric chloride, resulted in significantly greater lactate dehydrogenase release in LLC-cPLA2 cells when compared with control cells.

Therefore, arachidonic acid release from prelabelled cells as well as arachidonic acid incorporation into different phospholipid species under the influence of mercuric chloride (HgCl2), ethylmercurithiosalicylate (thimerosal), p-hydroxymercuribenzoic acid (PHMB), 0-(3-hydroxymercuri-3-methoxypropyl) carbamoyl-phenoxyacetic acid (mersalyl), N-ethylmaleimide (NEM), and ethacrynic acid were examined.
Additionally, direct effects of those substances on corresponding enzyme activities, i.e. phospholipase A2 (PLA2), acyl-CoA synthetase, and lysophospholipid acyltransferase (LAT), on glutathione levels, and on cell viability were estimated.

The rate of collapse of a proton gradient across the apical membrane of rat kidney proximal tubule increases upon treatment with calcium, mercuric chloride and mellitin, substances which activate phospholipase A2.

3364578 Chaudhari A, Kirschenbaum MA: Alterations in rabbit renal microvascular prostanoid synthesis in acute renal failure. Am J Physiol. 1988 May;254(5 Pt 2):F684-8.

This study assessed whether changes in two microvascular vasodilator prostanoids would correlate with changes seen in renal hemodynamics in rabbits with nephrotoxic renal injury produced by either uranyl nitrate or mercuric chloride.
These data suggest that the biosynthesis of prostacyclin and PGE2 may contribute to the maintenance of renal blood flow in the first few days after acute renal injury and further suggest that a mechanism for this increase may be stimulation of phospholipase A2.
