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

The DNA-binding domains (DBDs) of class I steroid receptors-androgen, glucocorticoid, progesterone and mineralocorticoid receptors-recognize a similar cis-element, an inverted repeat of 5'-AGAACA-3' with a 3-nt spacer. However, these receptors regulate transcription programs that are largely receptor-specific. To address the role of the DBD in and of itself in ensuring specificity of androgen receptor (AR) binding to chromatin in vivo, we used SPARKI knock-in mice whose AR DBD has the second zinc finger replaced by that of the glucocorticoid receptor. Comparison of AR-binding events in epididymides and prostates of wild-type (wt) and SPARKI mice revealed that AR achieves selective chromatin binding through a less stringent sequence requirement for the 3'-hexamer. In particular, a T at position 12 in the second hexamer is dispensable for wt AR but mandatory for SPARKI AR binding, and only a G at position 11 is highly conserved among wt AR-preferred response elements. Genome-wide AR-binding events agree with the respective transcriptome profiles, in that attenuated AR binding in SPARKI mouse epididymis correlates with blunted androgen response in vivo. Collectively, AR-selective actions in vivo rely on relaxed rather than increased stringency of cis-elements on chromatin. These elements are, in turn, poorly recognized by other class I steroid receptors.
