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

Sgs1 is a member of the RecQ family of DNA helicases, which have been implicated in genomic stability, cancer and ageing. Srs2 is another DNA helicase that shares several phenotypic features with Sgs1 and double sgs1srs2 mutants have a severe synthetic growth phenotype. This suggests that there may be functional overlap between these two DNA helicases. Consistent with this idea, we found the srs2Delta mutant to have a similar genotoxin sensitivity profile and replicative lifespan to the sgs1Delta mutant. In order to directly test if Sgs1 and Srs2 are functionally interchangeable, the ability of high-copy SGS1 and SRS2 plasmids to complement the srs2Delta and sgs1Delta mutants was assessed. We report here that SGS1 is a multicopy suppressor of the methyl methanesulphonate (MMS) and hydroxyurea sensitivity of the srs2Delta mutant, whereas SRS2 overexpression had no complementing ability in the sgs1Delta mutant. Domains of Sgs1 directly required for processing MMS-induced DNA damage, most notably the helicase domain, are also required for complementation of the srs2Delta mutant. Although SGS1 overexpression was unable to rescue the shortened mean replicative lifespan of the srs2Delta mutant, maximum lifespan was significantly increased by multicopy SGS1. We conclude that Sgs1 is able to partially compensate for the loss of Srs2.
