Cytosolic phospholipase A(2)α protects against Fas- but not LPS-induced liver injury.
Article in Journal of hepatology, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND &
aimsCytosolic phospholipase A(2)α (cPLA(2)α) is a rate-limiting key enzyme controlling the release of arachidonic acid (AA) substrate for the synthesis of prostaglandins and leukotrienes. This study was designed to explore the role of hepatocyte cPLA(2)α in Fas-mediated liver injury, in vivo.
methodsTransgenic mice with targeted expression of cPLA(2)α under control of the albumin-promoter enhancer and wild-type mice were injected intraperitoneally with anti-Fas antibody Jo2 or lipopolysaccharide plus d-galactosamine and monitored for liver injury and survival at various time points.
resultsThe cPLA(2)α Tg mice resist Fas-induced liver failure, as reflected by the lower serum transaminase levels, fewer apoptotic hepatocytes, reduced caspase activation, and reduced PARP cleavage when compared to the matched wild type mice. Inhibition of cPLA(2)α by its pharmacological inhibitor, pyrrolidine, enhanced Jo2-induced liver injury in both cPLA(2)α Tg and wild type mice. Hepatic overexpression of cPLA(2)α increases the expression of EGFR in the liver and the EGFR inhibitor, AG1478, exacerbated Jo2-mediated liver injury. The cPLA(2)α transgenic mice develop more prominent liver tissue damage than wild-type mice after LPS/d-galactosamine injection.
conclusionsHepatocyte cPLA(2)α protects against Fas-induced liver injury and this effect is mediated at least in part through the upregulation of EGFR.
