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

Nuclei of digitonin-permeabilized cells that had been preloaded with a model transport substrate in a cytosol-dependent import reaction were subsequently incubated to investigate which conditions would result in export of transport substrate. We found that up to 80% of the imported substrate was exported when recombinant human Ran and GTP were present in the export reaction. Ran-mediated export was inhibited by nonhydrolyzable GTP analogs and also by wheat germ agglutinin but was unaffected by a nonhydrolyzable ATP analog. Moreover, a recombinant human Ran mutant that was deficient in its GTPase activity inhibited export. These data indicate that export of proteins from the nucleus requires Ran and GTP hydrolysis but not ATP hydrolysis. We also found that digitonin-permeabilized cells were depleted of their endogenous nuclear Ran, thus allowing detection of Ran as a limiting factor for export. In contrast, most endogenous karyopherin alpha was retained in nuclei of digitonin-permeabilized cells. Unexpectedly, exogenously added, fluorescently labeled Ran, although it accessed the nuclear interior, was found to dock at the nuclear rim in a punctate pattern, suggesting the existence of Ran-binding sites at the nuclear pore complex.
