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

FoxA1-3 (formerly HNF3alpha, -beta, and -gamma), members of the FoxA subfamily of forkhead transcription factors, function as initial chromatin-binding and chromatin-remodeling factors in a variety of tissues, including liver and pancreas. Despite essential roles in development and metabolism, regulation of FoxA factors is not well understood. This study examines a potential role for acetylation in the regulation of FoxA chromatin binding and remodeling. Using in silico analysis, we have identified 11 putative p300 acetylation sites within FoxA1, five of which are located within wings 1 and 2 of its winged-helix DNA-binding domain. These polypeptide structures stabilize FoxA DNA and chromatin binding, and we have demonstrated that acetylation attenuates FoxA binding to DNA and diminishes its ability to remodel chromatin. FoxA acetylation is inhibited by chromatin binding. We propose a model whereby stable chromatin binding protects the FoxA DNA-binding domain from acetylation to preserve chromatin binding and remodeling by FoxA factors in the absence of extracellular cues.
