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 RNA polymerase II core promoter is a diverse and complex regulatory element. To gain a better understanding of the core promoter, we examined the motif 10 element (MTE), which is located downstream of the transcription start site and acts in conjunction with the initiator (Inr). We found that the MTE promotes the binding of purified TFIID to the core promoter and that the TAF6 and TAF9 subunits of TFIID appear to be in close proximity to the MTE. To identify the specific nucleotides that contribute to MTE activity, we performed a detailed mutational analysis and determined a functional MTE consensus sequence. These studies identified favored as well as disfavored nucleotides and demonstrated the previously unrecognized importance of nucleotides in the subregion of nucleotides 27 to 29 (+27 to + 29 relative to A(+1) in the Inr consensus) for MTE function. Further analysis led to the identification of three downstream subregions (nucleotides 18 to 22, 27 to 29, and 30 to 33) that contribute to core promoter activity. The three binary combinations of these subregions lead to the MTE (nucleotides 18 to 22 and 27 to 29), a downstream core promoter element (nucleotides 27 to 29 and 30 to 33), and a novel "bridge" core promoter motif (nucleotides 18 to 22 and 30 to 33). These studies have thus revealed a tripartite organization of key subregions in the downstream core promoter.
