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

Glial cell line-derived neurotrophic factor (GDNF) gene therapy could offer a disease-modifying treatment for Parkinson's disease (PD). Here, we report that plasmid DNA nanoparticles (NPs) encoding human GDNF administered intranasally to rats induce transgene expression in the brain and protect dopamine neurons in a model of PD. To first test whether intranasal administration could transfect cells in the brain, rats were sacrificed 1 week after intranasal pGDNF NPs or the naked plasmid. GDNF ELISA revealed significant increases in GDNF expression throughout the brain for both treatments. To assess whether expression was sufficient to protect dopamine neurons, naked pGDNF and pGDNF DNA NPs were given intranasally 1 week before a unilateral 6-hydroxydopamine lesion in a rat model of PD. Three to four weeks after the lesion, amphetamine-induced rotational behavior was reduced, and dopaminergic fiber density and cell counts in the lesioned substantia nigra and nerve terminal density in the lesioned striatum were significantly preserved in rats given intranasal pGDNF. The NPs afforded a greater level of neuroprotection than the naked plasmid. These results provide proof-of-principle that intranasal administration of pGDNF DNA NPs can offer a non-invasive, non-viral gene therapy approach for early-stage PD.
