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

Promoter recognition is the first and the most important step during gene expression. Our studies of the yeast (Saccharomyces cerevisiae) mitochondrial (mt) transcription machinery provide mechanistic understandings on the basic problem of how the mt RNA polymerase (RNAP) with the help of the initiation factor discriminates between promoter and non-promoter sequences. We have used fluorescence-based approaches to quantify DNA binding, bending, and opening steps by the core mtRNAP subunit (Rpo41) and the transcription factor (Mtf1). Our results show that promoter recognition is not achieved by tight and selective binding to the promoter sequence. Instead, promoter recognition is achieved by an induced-fit mechanism of transcription factor-dependent differential conformational changes in the promoter and non-promoter DNAs. While Rpo41 induces a slight bend upon binding both the DNAs, addition of the Mtf1 results in severe bending of the promoter and unbending of the non-promoter DNA. Only the sharply bent DNA results in the catalytically active open complex. Such an induced-fit mechanism serves three purposes: 1) assures catalysis at promoter sites, 2) prevents RNA synthesis at non-promoter sites, and 3) provides a conformational state at the non-promoter sites that would aid in facile translocation to scan for specific sites.
