BAC transgenic zebrafish reveal hypothalamic enhancer activity around obesity associated SNP rs9939609 within the human FTO gene.

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
Single Nucleotide Polymorphisms in FTO intron 1 have been associated with obesity risk, leading to the hypothesis that FTO is the obesity-related gene. However, other studies have shown that the FTO gene is part of the regulatory domain of the neighboring IRX3 gene and that enhancers in FTO intron 1 regulate IRX3. While Irx3 activity was shown to be necessary in the hypothalamus for the metabolic function of Irx3 in mouse, no enhancers with hypothalamic activity have been demonstrated in the risk-associated region within FTO. In order to identify potential enhancers at the human FTO locus in vivo, we tested regulatory activity in FTO intron 1 using BAC transgenesis in zebrafish. A minimal gata2 promoter-GFP cassette was inserted 1.3 kb upstream of the obesity associated SNP rs9939609 in a human FTO BAC plasmid. In addition to the previously identified expression domains in notochord and kidney, human FTO BAC:GFP transgenic zebrafish larvae expressed GFP in the ventral posterior tuberculum, the posterior hypothalamus and the anterior brainstem, which are also expression domains of zebrafish irx3a. In contrast, an in-frame insertion of a GFP cassette at the FTO start codon resulted in weak ubiquitous GFP expression indicating that the promoter of FTO does likely not react to enhancers located in the obesity risk-associated region.
