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

In previous reports we have demonstrated that the 60-aa peptide corresponding to the homeodomain of the Drosophila protein Antennapedia (pAntp) translocates through the membrane of neurons in culture, accumulates in neuronal nuclei, and promotes neurite growth. To analyze the importance of specific pAntp DNA-binding properties in this phenomenon we have constructed three mutant versions of pAntp that differ in their ability to translocate through the membrane and to bind specifically the cognate sequence for homeodomains present in the promoter of HoxA5. We demonstrate that removing two hydrophobic residues of the third helix inhibits pAntp internalization and suppresses its neurotrophic activity. We also show that pAntp neurotrophic activity is lost when mutations are introduced in positions preserving its penetration and nuclear accumulation but abolishing its capacity to bind specifically the cognate DNA-binding motif for homeoproteins. Our results strongly suggest that pAntp neurotrophicity requires both its internalization and its specific binding to homeobox cognate sequences. We propose that homeoproteins might regulate important events in the morphological differentiation of the postmitotic neuron.
