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

Intracellular trafficking of tRNA was long thought to be a one-way trip from the site of biogenesis in the nucleus to the translation machinery in the cytoplasm. This view has recently been challenged, however, by the discovery that tRNA can move retrograde from the cytoplasm back to the nucleus in Saccharomyces cerevisiae and rat hepatoma H4IIE cells during nutrient stress and in S. cerevisiae after intron-containing pre-tRNAs are spliced in the cytoplasm. Contrary to studies reported, we present data suggesting that nutrient stress does not cause retrograde transport of cytoplasmic tRNAs to the nucleus in rat hepatoma H4IIE cells, human HeLa and HEK293 cells, and the yeasts Kluyveromyces lactis and S. cerevisiae. However, the efficiency of nuclear re-export of retrograded spliced tRNA was severely affected in S. cerevisiae and two other Saccharomyces species deprived of nutrient. Collectively, the data suggest that nutrient stress does not cause nuclear import of cytoplasmic tRNA; instead, nutrient stress specifically regulates nuclear re-export of retrograded spliced tRNAs but not nuclear export of tRNAs made from intronless pre-tRNAs in Saccharomyces species. Furthermore, we provide evidence suggesting that Mtr10p and the Gsp1pGTP/Gsp1pGDP cycle are not involved in nuclear tRNA import in S. cerevisiae during nutrient stress.
