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

Giardia lamblia, the protist that causes diarrhea, makes an Asn-linked-glycan (N-glycan) precursor that contains just two sugars (GlcNAc(2)) attached by a pyrophosphate linkage to a polyprenol lipid. Because the candidate cis-prenyltransferase of Giardia appears to be more similar to bacterial enzymes than to those of most eukaryotes and because Giardia is missing a candidate dolichol kinase (ortholog to Saccharomyces cerevisiae SEC59 gene product), we wondered how Giardia synthesizes dolichol phosphate (Dol-P), which is used to make N-glycans and glycosylphosphatidylinositol (GPI) anchors. Here we show that cultured Giardia makes an unsaturated polyprenyl pyrophosphate (dehydrodolichol), which contains 11 and 12 isoprene units and is reduced to dolichol. The Giardia cis-prenyltransferase that we have named Gl-UPPS because the enzyme primarily synthesizes undecaprenol pyrophosphate is phylogenetically related to those of bacteria and Trypanosoma rather than to those of other protists, metazoans and fungi. In transformed Saccharomyces, the Giardia cis-prenyltransferase also makes a polyprenol containing 11 and 12 isoprene units and supports normal growth, N-glycosylation and GPI anchor synthesis of a rer2Delta, srt1Delta double-deletion mutant. Finally, despite the absence of an ortholog to SEC59, Giardia has cytidine triphosphate-dependent dolichol kinase activity. These results suggest that the synthetic pathway for Dol-P is conserved in Giardia, even if some of the important enzymes are different from those of higher eukaryotes or remain unidentified.
