1 · What the graph read from it

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.

2 · The registry

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

Evidence indicates that mitogen-activated protein kinase (MAPK) pathways play a crucial role in the neurobiology of the nervous system. In the present study, dopamine receptor-mediated regulation of extracellular signal-regulated kinases (ERKs) was examined in rats in which the nigrostriatal dopaminergic pathway was unilaterally lesioned by 6-hydroxydopamine (6-OHDA). Subcutaneous injections of the D(2) receptor agonist quinpirole significantly increased tyrosine-phosphorylated ERK1/2 in lesioned striatum, whereas the D(1) receptor agonist SKF38393 failed to activate ERKs. Quinpirole-induced phosphorylation of ERK1/2 was seen as early as 3 min and peaked at 15 min after the challenge. In parallel, striatal ERK kinase activity, measured by the in vitro kinase assay, was increased 2.5-fold on the lesioned side after the administration of quinpirole. Immunohistochemical examination of brain sections after quinpirole administration revealed significant increases in ERK1/2 immunostaining in perinuclear and intranuclear areas of striatal neurons. This increase was much more pronounced on the lesioned than the intact side. Furthermore, quinpirole-induced contralateral rotation was decreased by 48.7 and 50.7%, respectively, when the striatal ERK pathway was selectively inhibited by a single intrastriatal injection of the MAPK/ERK kinase inhibitor PD098059 or after a continuous 7 d intrastriatal infusion of ERK1/2 antisense oligodeoxynucleotide. The results demonstrate, for the first time, that the ERK signaling pathway is activated in denervated striatum in response to stimulation of D(2) dopamine receptors and that the resulting imbalance in striatal ERK activity contributes, at least in part, to neuronal plasticity that underlies D(2) dopamine receptor-mediated contralateral rotation in unilateral 6-OHDA denervated rats.
