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

Transcriptional activation by nuclear receptors is achieved through autonomous activation functions (AFs), a constitutive N-terminal AF-1 and a C-terminal, ligand-dependent AF-2 that comprises a motif conserved between nuclear receptors. We have performed an extensive mutational analysis of the putative AF-2 domain of chicken thyroid hormone receptor alpha (cT3R alpha). We show that the AF-2 region mediates transactivation as well as transcriptional interference (squelching), not only between the thyroid hormone and vitamin (type II) receptors, but also between type II and steroid hormone (type I) receptors. Transcriptional activation and interference require equivalent doses of the cognate ligand, and mutations in the conserved motif that reduce ligand-induced transactivation also impair transcriptional interference. When fused to the Gal4 DNA binding domain, a 35 amino acid long fragment containing the conserved motif is able to transactivate and squelch, albeit in a ligand-independent manner. Our results define the AF-2 of cT3R alpha as an autonomous transactivation domain that, in its natural context, is governed by ligand. We propose that AF-2 is probably part of a surface for interaction with either a general transcription factor or a putative bridging factor, that might be utilized by type I and II receptors.
