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

objectiveId2 (inhibitor of DNA-binding 2), a member of the helix-loop-helix family of transcription regulators, plays important roles in cell proliferation and differentiation. Recent reports have documented that Id2 is up-regulated during vascular lesion formation and overexpression of Id2 promotes vascular smooth muscle cell (VSMC) proliferation. However, the transcriptional regulation of Id2 gene expression in VSMC remains unexplored. METHODS AND

resultsUsing Northern- and Western-blot analyses, we documented that interleukin-1beta (IL-1beta) induced Id2 gene expression in VSMC in a time- and dose-dependent manner. Overexpression of early growth response-1 (Egr-1) in VSMC induced Id2 expression while IL-1beta-induced Id2 expression was abrogated in VSMC by the Egr-1 repressor, NGFI-A binding protein 2 (NAB2), expressed from an adenovirus. Overexpression of Egr-1 transactivated the Id2 promoter in reporter assays dependent on the presence of intact putative Egr-1 binding sites as determined by mutagenesis. Finally, electrophoretic mobility shift assays (EMSA) demonstrated that the Egr-1 protein can bind the Egr-1 sites derived from the human Id2 promoter in vitro and chromatin immunoprecipitation identified the putative Egr-1 site between -723 to -712 as the functional Egr-1 binding site in vivo.

conclusionsOur data demonstrate that IL-1beta-induced Id2 expression in VSMC is mediated by the transcription factor Egr-1 in VSMC.
