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

Vimentin, a member of the intermediate filament protein family, exhibits tissue- as well as development-specific expression. Transcription factors that are involved in expression of the chicken vimentin gene have been described and include a cis-acting silencer element (SE3) that is involved in the down-regulation of this gene (F. X. Farrell, C. M. Sax, and Z. E. Zehner, Mol. Cell. Biol. 10:2349-2358, 1990). In this study, we report the identification of two additional silencer elements (SE1 and SE2). We show by transfection analysis that all three silencer elements are functionally active and that optimal silencing occurs when multiple (at least two) silencer elements are present. In addition, the previously identified SE3 can be divided into three subregions, each of which is moderately active alone. By gel mobility shift assays, all three silencer elements plus SE3 subregions bind a protein which by Southwestern (DNA-protein) blot analysis is identical in molecular mass (approximately 95 kDa). DNase I footprinting experiments indicate that this protein binds to purine-rich sites. Therefore, multiple elements appear to be involved in the negative regulation of the chicken vimentin gene, which may be important in the regulation of other genes as well.
