Cross-talk between enhancers, structural elements and activating transcription factors maintains the 3D architecture and expression of the CFTR 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
Robust protocols to examine 3D chromatin structure have greatly advanced knowledge of gene regulatory mechanisms. Here we focus on the cystic fibrosis transmembrane conductance regulator (CFTR) gene, which provides a paradigm for validating models of gene regulation built upon genome-wide analysis. We examine the mechanisms by which multiple cis-regulatory elements (CREs) at the CFTR gene coordinate its expression in intestinal epithelial cells. Using CRISPR/Cas9 to remove CREs, individually and in tandem, followed by assays of gene expression and higher-order chromatin structure (4C-seq), we reveal the cross-talk and dependency of two cell-specific intronic enhancers. The results suggest a mechanism whereby the locus responds when CREs are lost, which may involve activating transcription factors such as FOXA2. Also, by removing the 5' topologically-associating domain (TAD) boundary, we illustrate its impact on CFTR gene expression and architecture. These data suggest a multi-layered regulatory hierarchy that is highly sensitive to perturbations.
