a simple gas chromatographic method for the assay of phospholipase A2 (PLA2) has been described in which arachidonic acid released from endogenous phospholipid pools is measured following its extraction and derivatization to pentafluorobenzyl esters. Using this assay, PLA2 activities in

Ceramide is a novel second messenger generated by hydrolysis of membrane sphingomyelin by a neutral sphingomyelinase (nSMase). Cytokines such as tumor necrosis factor-alpha (TNF-alpha) have been shown to increase intracellular ceramide through phospholipase A2 (PLA2)-dependent activation of nSMase. TNF-alpha has

Activity of the epithelial Na+ channel (ENaC) is the limiting step for discretionary Na+ reabsorption in the cortical collecting duct. Xenopus laevis kidney A6 cells were used to investigate the effects of cytosolic phospholipase A2 (cPLA2) activity on Na+ transport.

Globoid cell leukodystrophy (Krabbe disease) is an inherited neurological disorder caused by the pathogenomic accumulation of psychosine (galactosylsphingosine), a substrate for the deficient enzyme galactocerebroside beta-galactosidase. This study underscores the mechanism of action of psychosine in the regulation of oligodendrocyte

In this paper we show that exposure of a rat brain synaptosome fraction to the amyloid beta peptide fragment betaA(25-35), but not the inverted peptide betaA(35-25), stimulated production of reactive oxygen species (ROS) in a concentration- and time-dependent manner. The
