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

An allosteric ribozyme consisting of a metabolite-sensing riboswitch and a group I self-splicing ribozyme was recently found in the pathogenic bacterium Clostridium difficile. The riboswitch senses the bacterial second messenger c-di-GMP, thereby controlling 5'-splice site choice by the downstream ribozyme. The proximity of this allosteric ribozyme to the open reading frame (ORF) for CD3246 suggests that coenzyme-mediated regulation of splicing controls expression of this putative virulence gene. In the presence of c-di-GMP, the allosteric ribozyme in the CD3246 precursor transcript generates a spliced transcript that retains the riboswitch aptamer. In the absence of c-di-GMP, the ribozyme mediates an alternative GTP attack that results in a truncated transcript (alternative GTP-attack product). Using reporter assays in Escherichia coli, we investigated the difference in gene expression between the spliced product and the alternative GTP-attack product. We provide evidence that CD3246 gene expression is activated if allosteric ribozyme splicing creates a ribosome binding site (RBS) for translation from a UUG start codon. In addition, biochemical and genetic analyses reveal that the riboswitch may further control CD3246 expression by revealing or occluding this newly formed RBS. Therefore, this architecture provides the riboswitch with a mechanism for extended regulation after splicing has occurred or as a backup mechanism for suppression of translation in the event of misregulated splicing.
