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

In many organisms, meiotic recombination occurs preferentially at a limited number of sites in the genome known as hotspots. In the fission yeast Schizosaccharomyces pombe, simple sequence motifs determine the location of at least some, and possibly most or all, hotspots. Recently, we showed that a large number of different sequences can create hotspots. Among those sequences we identified some recurring motifs that fell into at least five distinct families, including the well-characterized CRE family of hotspots. Here we report the essential sequence for activity of two of the novel hotspots, the oligo-C and CCAAT hotspots, and identify associated trans-acting factors required for hotspot activity. The oligo-C hotspot requires a unique 8-bp sequence, CCCCGCAC, though hotspot activity is also significantly affected by adjacent nucleotides. The CCAAT hotspot requires a more complex and degenerate sequence, including the originally identified seven nucleotide CCAATCA sequence at its core. We identified transcription factors, the CCAAT-binding factor (CBF) and Rst2, which are required specifically for activity of the CCAAT hotspots and oligo-C hotspots, respectively. Each of these factors binds to its respective motifs in vitro. However, unlike CRE, the sequence required for hotspot activity is larger than the sequence required for binding, suggesting the involvement of additional factors.
