Adenovirus vector-directed expression of the neurotrophin-3 receptor (TrkC) in mouse astrocytes.

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
In the present article we report the generation of a neurovirological reagent, an adenovirus vector that efficiently delivers the gene for the Neurotrophin-3 (NT-3) receptor, TrkC. Using this AdTrkC vector, we examined the induction of the expression of the above neurotrophin receptor in pure cultures of mouse astrocytes, a glial cell type that does not constitutively express this gene. Infection of astrocytes at an optimal dose of 100-200 plaque forming units (p.f.u.) per cell, induced expression of specific mRNA, as demonstrated by RT-PCR and Northern blot. This mRNA was translated to produce a mean of 20,157 biologically active receptor molecules per astrocyte with a Kd of 4.1 x 10(-11) M, as demonstrated by 125I-NT-3 binding. After 2D electrophoresis, the mature glycoprotein and some precursors were recognised by antibodies raised against the carboxy-terminal peptide of Trk. Binding of the ligand induced autophosphorylation ofTrkC and 3H-thymidine incorporation in transduced cells. These results demonstrate that our AdTrkC vector efficiently mediates the expression of high-levels of biologically active NT-3 receptors.
