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

A group of cytoprotective genes is regulated by heterodimers composed of the cap'n'collar (CNC) family member Nrf2 and one of the small Maf (sMaf) proteins (MafF, MafG, or MafK) through the antioxidant response element (ARE, also referred to as the CNC-sMaf binding element [CsMBE]). Many lines of evidence support this model; however, a direct and specific evaluation of the Nrf2-sMaf heterodimer remains to be executed. To address this issue, we constructed a tethered Nrf2-MafG (T-N2G) heterodimer using a flexible linker peptide. We then introduced the T-N2G construct into cells lacking all three sMaf proteins to specifically evaluate the function of the tethered heterodimer without interference from other endogenous CNC-sMaf heterodimers or sMaf homodimers. In response to an Nrf2 activator, diethyl maleate, the T-N2G protein can widely activate the target genes of Nrf2 but not those of Nrf1, such as proteasome subunit genes. Genome-wide binding analysis showed that the T-N2G protein preferentially bound to the CsMBE motifs in the regulatory regions of the Nrf2 target genes. These results provide direct evidence that the Nrf2-MafG heterodimer acts as a transcriptional activator of Nrf2-dependent genes and show that this assay system will be a powerful tool to specifically examine the function of other CNC-sMaf heterodimers.
