Setting of graded levels of a protein in yeast by a t-degron technique as applied to phosphoglycerate mutase.
Article in BMC genetics, 2002. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundSetting of graded levels of a protein for in vivo studies by controlled gene expression has inconveniences, and we here explore the use of the t-degron technique instead.
resultsIn a yeast t-degron (ubiquitin-argDHFR(ts))- phosphoglycerate mutase (GPM1) fusion strain, increasing periods of exposure to the non-permissive temperature 37 degrees C, even in the presence of cycloheximide, gave decreasing function, as assessed at 23 degrees C in vivo by glucose metabolism and confirmed by immunoblot.
conclusionAn ideal system would set a range of lower levels of a protein, do so without compensating protein synthesis, and give stable activity for in vitro comparisons. Although the first two aims appear obtainable, the third was not in this example of the application, limiting its uses for some but not all purposes.
