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

A new type of DNA transposon, Mutyl, has been identified in the sequenced genome of the yeast Yarrowia lipolytica. This transposon is 7,413 bp long and carries two open reading frames (ORFs) which potentially encode proteins of 459 and 1,178 amino acids, respectively. Whereas the first ORF shows no significant homology to previously described proteins, the second ORF shows sequence similarities with various Mutator-like element (MULE)-encoded transposases, including the bacterial transposase signature sequence. Other MULE features shared by Mutyl include a zinc finger motif in the putative transposase, a 22-bp-long imperfect inverted repeat at each end, and a 9- to 10-bp duplication of its target site in the chromosome. Of the five copies of Mutyl present in the genome, one has a deletion of the first 8 bases, and the others are full length with a single base change in one element. The first potential gene of Mutyl, mutB, was shown to be expressed in exponentially growing cells. Its sequence contains a predicted intron with two 5' splice sites, a single branch point, and two 3' splice sites. Its mRNA is alternatively spliced, as judged by reverse transcription-PCR, and generates four mRNAs corresponding to protein-coding sequences of 128, 156, 161, and 190 amino acids. Of the three distinct lineages characterized in Y. lipolytica, strains from the German lineage and the French lineage do not carry Mutyl. A study of the distribution of Mutyl in strains of the French lineage evidenced a recent transposition event. Taken together, these results indicate that Mutyl is still active.
