Tyrosine phosphorylation of insulin receptor substrates during ischemia/reperfusion-induced apoptosis in rat liver.
Article in Langenbeck's archives of surgery, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundPhosphoregulation of signal transduction pathways is a complex series of reactions that may modulate the cellular response to ischemia-reperfusion (I-R). The aim of this study was to evaluate the effect of normothermic liver I/R-induced apoptosis on phosphorylation and activation of signal proteins in tyrosine kinase pathways. MATERIALS AND
methodsIn rats, a segmental normothermic ischemia of the liver was induced for 120 min. Liver apoptosis was determined using terminal deoxynucleotide-transferase-mediated deoxyuridine triphosphate nick end labeling assay, and activity of caspases-3 and -7 was determined by fluorescence. Liver tyrosine phosphorylation of proteins was examined by Western blot analysis.
resultsNormothermic I-R resulted in increased in vivo caspases-3 and -7 activity and in liver apoptosis. Shc tyrosine phosphorylation and activation of ERK1/2 were increased after reperfusion, while tyrosine phosphorylation of IRS-1 and activation of PKB/Akt were decreased.
conclusionsNormothermic liver I-R leads to increased apoptosis and to modifications in protein tyrosine phosphorylation pathways.
