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

Many details of structure, function and substrate specificity of eukaryotic proteasomal systems have been elucidated. This information far-exceeds that available for the archaeal and bacterial counterparts. While structural and functional studies have provided some insight into the workings of prokaryotic proteasomes, the question of substrate targeting and global cellular influence remain largely unaddressed. In this communication, we report an over 720-fold increase in the half-life of the DNA-sliding clamp protein proliferating cell nuclear antigen after knockout of the panA gene, encoding a proteasome-activating nucleotidase A, on the chromosome of the halophilic archaeon Haloferax volcanii. This discovery marks the first identification of a protein stabilized by an archaeal proteasome mutation and provides a starting point for investigations into substrate recognition mechanisms. The findings also begin to address the functional role of proteasomal systems within the scope of the archaeal cell.
