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

The yKu protein of Saccharomyces cerevisiae is important for genome stability by repressing recombination involving telomeric sequences. The mechanism of this repression is not known, but silent heterochromatin such as HML, HMR, and telomeres are compartmentalized at the nuclear periphery and yKu is proposed to interact with these regions and to play a role in telomeric silencing and tethering. We have utilized ChIP on chip, quantitative PCR, and quantitative recombination assays to analyze yKu binding and its effect on genome stability in wild-type and mutant backgrounds. Our data suggest that, although yKu binds to the TG1-3 repeats and other parts of the genome when needed, such as during nonhomologous end-joining, it specifically binds to core X sequences in addition to the mating-type loci, HML and HMR. Association with core X occurred in the absence of Sir proteins, and enhanced binding was observed at silenced ends compared to nonsilenced ends. In contrast, binding to HML and HMR was totally dependent on Sir2-4p and partially dependent on Sir1p with a stronger association at HML in both MATa and MATalpha strains. Using yku80 separation-of-function mutants, we show a direct correlation between core X binding and recombination rate. We believe our findings support our hypothesis that yKu and core X play a pivotal role in maintaining genome stability through nuclear architecture by mediating a defensive fold-back structure at yeast chromosome ends.
