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

DEC1 is a transcription repressor that is induced by Hypoxia-Inducible Factor-α/β (HIF-α/β). In this study, we found that either hypoxic treatment or ectopic expression of DEC1 blocks induction of a master adipogenic transactivator, peroxisome proliferative activated receptor-γ2 (PPARγ2) in 3T3-L1 cells. DEC1 did not prevent C/EBPβ, which is an upstream transactivator for PPARγ2, from occupying the PPARγ2 promoter. DEC1 occupied the PPARγ2 promoter by interacting with DNA-bound C/EBPβ. DEC1 occupancy was accompanied by a reduction of acetylated histones and an increase in histone deacetylase 1 (HDAC1) occupancy on the PPARγ2 promoter. Based on the fact that DEC1 interacts with HDAC1, this study suggests that DEC1 blocks adipogenesis by reinforcing HDAC1 recruitment to the PPARγ2 promoter. This study implies that DEC1 is one of the mediators that reset the pattern of PPARγ2 expression in response to hypoxia.
