Characterization and Functional Assessment of Mouse PPARγ1 Promoter.

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
backgroundPeroxisome Proliferator Activated Receptor gamma (PPARγ), a member of nuclear receptor superfamily, comprises two isoforms in mouse. These two isoforms are encoded by different mRNAs, which are arisen by alternative promoter usage. There are two promoter regions upstream of PPARγ gene. A 3 kb fragment, containing several transcription factor binding sites, acts as PPARγ1 promoter region. Thus, expression pattern of PPARγ1 isoform is due to the potential transcription factors that could influence its promoter activity. PPARγ, Retinoid X Receptor (RXR) and Vitamin D Receptor (VDR), as nuclear receptors could influence PPARγ gene expression pattern during several differentiation processes. During neural differentiation, PPARγ1 isoform expression reaches to maximal level at neural precursor cell formation.
methodsA vast computational analysis was carried out to reveal the PPARγ1 promoter region. The putative promoter region was then subcloned upstream of an EGFP reporter gene. Then the functionality of PPARγ1 promoter was assessed in different cell lines.
resultsResults indicated that Rosiglitazone increased PPARγ1 promoter regulated EGFP expression of neural precursor cells during Embryoid Body (EB) formation. Furthermore vitamin D reduced PPARγ1 promoter regulated EGFP expression of neural precursor cells during EB formation through binding to its receptor.
conclusionThis study suggests that there are potential response elements for PPAR/RXR and VDR/RXR heterodimers in PPARγ1 isoform promoter. Also VDR/RXR heterodimers may decrease PPARγ expression through binding to its promoter.
