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

Although RNA polymerases (RNAPs) are able to use RNA as template, it is unknown how they recognize RNA promoters. In this study, we used an RNA fragment derived from the hepatitis delta virus (HDV) genome as a model to investigate the recognition of RNA promoters by RNAP II. Inhibition of the transcription reaction using an antibody specific to the largest subunit of RNAP II and the direct binding of purified RNAP II to the RNA promoter confirmed the involvement of RNAP II in the reaction. RNA affinity chromatography established that an active RNAP II preinitiation complex forms on the RNA promoter and indicated that this complex contains the core RNAP II subunit and the general transcription factors TFIIA, TFIIB, TFIID, TFIIE, TFIIF, TFIIH and TFIIS. Binding assays demonstrated the direct binding of the TATA-binding protein and suggested that this protein is required to nucleate the RNAP II complex on the RNA promoter. Our findings provide a better understanding of the events leading to RNA promoter recognition by RNAP II.
