Biochemical analyses of transcriptional regulatory mechanisms in a chromatin context.
Article in Methods (San Diego, Calif.), 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
We have optimized a recombinant chromatin assembly system that properly incorporates core histones and histone H1 into a chromatin template containing a natural promoter sequence. This article provides a step-by-step procedure for expression and purification of the proteins required for assembling well-defined chromatin templates. We describe how to measure the degree of chromatin assembly in the absence and presence of histone H1 using topological analysis and how to perform micrococcal nuclease digestion to confirm H1 incorporation and determine the quality of in vitro chromatin templates. Further, we describe the use of sucrose gradient ultracentrifugation to verify that no unincorporated H1 remains as a second means for deciding on the proper H1 to core histone ratio during assembly. Additionally, we discuss the use of both yeast and Drosophila NAP-1 (yNAP-1 and dNAP-1, respectively) in the assembly of H1-containing chromatin. Finally, we provide detailed description of functional assays for investigating the mechanism of transcriptional regulation in a chromatin context (transcription, histone acetyltransferase activity, and protein association with promoter-bound complexes using immobilized chromatin templates).
