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 human aryl hydrocarbon receptor (hAHR) and mouse aryl hydrocarbon receptor (mAHR(b)) share limited (58%) transactivation domain (TAD) sequence identity. Compared to the mAHR(b) allele, the hAHR displays 10-fold lower relative affinity for prototypical ligands, such as 2,3,7,8 tetrachlorodibenzo-p-dioxin (TCDD). However, in previous studies, we have demonstrated that the hAHR can display a higher relative ligand-binding affinity than the mAHR(b) for specific AHR ligands, such as indirubin. Each receptor has also been shown to differentially recruit LXXLL coactivator motif proteins and to utilize different TAD subdomains in gene transactivation. Using hepatocytes isolated from C57BL/6J mice (Ahr(b/b)) and AHR(Ttr) transgenic mice, which express hAHR protein specifically in hepatocytes, we investigated whether the hAHR and mAHR(b) differentially regulate genes. DNA microarray and quantitative PCR analysis of Ahr(b/b) and AHR(Ttr) primary mouse hepatocytes treated with 10nM TCDD revealed that a number of established AHR target genes such as Cyp1a1 and Cyp1b1 are significantly induced by both receptors. Remarkably, of the 1752 genes induced by mAHR(b) and 1186 genes induced by hAHR, only 265 genes (approximately 18%) were significantly activated by both receptors in response to TCDD. Conversely, of the 1100 and 779 genes significantly repressed in mAHR(b) and hAHR hepatocytes, respectively, only 462 (approximately 49%) genes were significantly repressed by both receptors in response to TCDD treatment. Genes identified as differentially expressed are known to be involved in a number of biological pathways, including cell proliferation and inflammatory response, which suggest that compared to the mAHR(b), the hAHR may play contrasting roles in TCDD-induced toxicity and endogenous AHR-mediated gene regulation.
