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

Phospholipid biosynthetic genes encode enzymes responsible for phospholipid biosynthesis. They are coordinately regulated by the availability of phospholipid precursors through the inositol-sensitive upstream activating sequence (UAS(INO)). However, not all phospholipid genes are UAS(INO)-containing genes and not all UAS(INO)-containing genes have the same response to the phospholipid precursors. Therefore, the transcriptional regulation of phospholipid genes in response to the availability of phospholipid precursors is still unclear. Here, 22 out of 47 phospholipid biosynthetic genes were identified as UAS(INO)-containing genes, including EKI1, EPT1, INM1, IPK2, KCS1, PAH1, and PIK1 which have never been reported before. We also showed, using qRT-PCR technique, that 12 UAS(INO)-containing genes are down-regulated by 100 μM inositol in the wild type cells and up-regulated by 100 μM inositol in the ino2Δ cells. Therefore, it is possible that these genes are transcriptionally regulated by the UAS(INO) through the negative response of Ino2p to inositol. One other UAS(INO)-containing gene might be regulated by the positive response of Ino2p to 100 μM inositol. Surprisingly, we found 9 UAS(INO)-containing genes are not dependent on the response of Ino2p to 100 μM inositol, indicating that they may be regulated by other pathway. Furthermore, we identified 9 and 3 non-UAS(INO)-containing genes that are possibly regulated by the negative and positive response of Ino2p to 100 μM inositol, respectively. Therefore, these observations provide insight into the understanding of the co-regulated phospholipid biosynthetic genes expression.
