Proteomic characterization of the arsenic response locus in S. cerevisiae.
Article in Epigenetics, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Arsenic exposure is a global health problem. Millions of people encounter arsenic through contaminated drinking water, consumption, and inhalation. The arsenic response locus in budding yeast is responsible for the detoxification of arsenic and its removal from the cell. This locus constitutes a conserved pathway ranging from prokaryotes to higher eukaryotes. The goal of this study was to identify how transcription from the arsenic response locus is regulated in an arsenic dependent manner. An affinity enrichment strategy called CRISPR-Chromatin Affinity Purification with Mass Spectrometry (CRISPR-ChAP-MS) was used, which provides for the proteomic characterization of a targeted locus. CRISPR-ChAP-MS was applied to the promoter regions of the activated arsenic response locus and uncovered 40 nuclear-annotated proteins showing enrichment. Functional assays identified the histone acetyltransferase SAGA and the chromatin remodelling complex SWI/SNF to be required for activation of the locus. Furthermore, SAGA and SWI/SNF were both found to specifically organize the chromatin structure at the arsenic response locus for activation of gene transcription. This study provides the first proteomic characterization of an arsenic response locus and key insight into the mechanisms of transcriptional activation that are necessary for detoxification of arsenic from the cell.
