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 high-affinity receptor for immunoglobulin E (IgE), FcepsilonRI, is specifically expressed in mast cells and basophils and plays a key role in IgE-mediated allergic reactions. The transcription factor Elf-1 has been previously identified to bind to the promoter of the human FcepsilonRI alpha-chain, which is essential for the function and expression of FcepsilonRI. In the present study, Elf-1 siRNA was conducted to evaluate the effects of Elf-1 on FcepsilonRI alpha-chain expression in the primary mouse mast cells, bone marrow-derived mast cells (BMMC). Introduction of Elf-1 siRNA effectively reduced expression levels of Elf-1 mRNA and protein in BMMC. Transient reporter assay showed that the knockdown of Elf-1 by siRNA resulted in increased FcepsilonRI alpha-chain promoter activity, while overexpression of Elf-1 suppressed alpha-chain promoter activity in BMMC. Elf-1 siRNA-treated BMMC exhibited marked upregulation of FcepsilonRI alpha-chain transcription, whereas beta-chain mRNA was not affected by Elf-1 siRNA. Chromatin immunoprecipitation assay showed that the amount of transcription factor PU.1, recognizing the cis-element close to the Elf-1-site on the FcepsilonRI alpha-chain promoter, was significantly increased by introduction of Elf-1 siRNA. These results indicate that Elf-1 negatively regulates FcepsilonRI alpha-chain expression by suppressing PU.1-mediated transcription of the alpha-chain in BMMC.
