Quantitative Analysis of Catecholamines in the Pink1 -/- Rat Model of Early-onset Parkinson's Disease.

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
Parkinson's disease (PD) related to homozygous mutations in the Pink1 gene is associated with nigrostriatal dopamine depletion and a wide range of sensorimotor deficits. In humans and animal models of PD, not all sensorimotor deficits are levodopa-responsive. We hypothesized that the underlying mechanisms of locomotion, limb control, and vocal communication behavior include other pathologies. Here, Pink1 -/- rats were treated with an oral dose of levodopa and limb motor and vocal communication behaviors were measured. Levodopa significantly improved some aspects of locomotion but did not improve ultrasonic vocalization intensity or frequency. Catecholamine concentrations in the striatum (SR), substantia nigra (SN), and locus coeruleus (LC) were analyzed to test the hypothesis that behavioral deficits would correlate to altered protein levels. There were no differences in dopamine concentrations in the SR and SN of Pink1 -/- animals compared to wild-type controls. There was a significant increase in norepinephrine concentration in the SN of Pink1 -/- animals. Moreover, an observed decrease in norepinephrine concentrations in the LC is consistent with the hypothesis that early-stage PD includes noradrenergic loss in the brainstem, and is congruent with a significant increase in catechol-O-methyltransferase expression in the LC of Pink1 -/- animals. Pearson's correlations showed that increases in time to traverse a tapered balance beam are significantly associated with reductions in striatal dopamine. Ultrasonic vocalization complexity was positively correlated with LC norepinephrine concentrations. These data support the evolving hypothesis that differences in neural substrates and early-onset noradrenergic mechanisms in the brainstem may contribute to pathogenesis in the Pink1 -/- rat.
