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

Bacteria use complex strategies to coordinate temperature-dependent gene expression. Many genes encoding heat shock proteins and virulence factors are regulated by temperature-sensing RNA sequences, known as RNA thermometers (RNATs), in their mRNAs. For these genes, the 5' untranslated region of the mRNA folds into a structure that blocks ribosome access at low temperatures. Increasing the temperature gradually shifts the equilibrium between the closed and open conformations towards the open structure in a zipper-like manner, thereby increasing the efficiency of translation initiation. Here, we review the known molecular principles of RNAT action and the hierarchical RNAT cascade in Escherichia coli. We also discuss RNA-based thermosensors located upstream of cold shock and other genes, translation of which preferentially occurs at low temperatures and which thus operate through a different, more switch-like mechanism. Finally, we consider the potential biotechnological applications of natural and synthetic RNATs.
