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 thyroid hormone receptor (TR) regulates the transcription of its target genes by interacting with specific hormone response elements consisting usually of directly repeated half-sites with the consensus sequence AGGTCA. To investigate the role of the spacer sequences separating the half-sites, heterodimers formed by TRalpha and the retinoid-X receptor (RXR) were used in a PCR based selection and amplification assay. The TRalpha/RXR heterodimer selected for elements with directly repeated half-sites having a spacer of 4 nucleotides (DR4). Preferences for nucleotides in the TR binding half-site motif as well as for the 4 nucleotides separating the two half-sites were found. DNA binding and transfection studies using DR4 elements with different spacer sequences showed the importance of these nucleotides for the activity of the response element: some spacer sequences allowed little or no transactivation from the element, whereas other sequences supported strong transactivation. A pyrimidine nucleotide in position three of the spacer enhanced TRalpha binding and transactivation. Additional experiments showed that heterodimers between RXR and other putative receptors exhibited a similar but distinct specificity for the spacer sequence. Our results thus suggest that the four nucleotides separating the two half-sites in hormone response elements have a major role in determining induction of hormone responsive genes.
