Naturally Occurring Amino Acids in Helix 10 of the Thyroid Hormone Receptor Mediate Isoform-Specific TH Gene Regulation.

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.
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
Thyroid hormone (TH) action is mediated by the products of two genes, TH receptor (THR)α (THRA) and THRβ (THRB) that encode several closely related receptor isoforms with differing tissue distributions. The vast majority of THR isoform-specific effects are thought to be due to tissue-specific differences in THR isoform expression levels. We investigated the alternative hypothesis that intrinsic functional differences among THR isoforms mediate these tissue-specific effects. To achieve the same level of expression of each isoform, we created tagged THR isoforms and tested their DNA and functional properties in vitro. We found significant homodimerization and functional differences among the THR isoforms. THRA1 was unable to form homodimers on direct repeat separated by 4 bp DNA elements and was also defective in TH-dependent repression of Tshb and Rxrg in a thyrotroph cell line, TαT1.1. In contrast, THRB2 was both homodimer sufficient and fully functional on these negatively regulated genes. Using domain exchanges and individual amino acid switches between THRA1 and THRB2, we identified three amino acids in helix 10 of the THRB2 ligand-binding domain that are required for negative regulation and are absent in THRA1.
