A ChIP-on-chip tiling array approach detects functional histone-free regions associated with boundaries at vertebrate HOX genes.
Article in Genomics data, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Hox genes impart segment identity to body structures along the anterior-posterior axis and are crucial for proper development. A unique feature of the Hox loci is the collinearity between the gene position within the cluster and its spatial expression pattern along the body axis. However, the mechanisms that regulate collinear patterns of Hox gene expression remain unclear, especially in higher vertebrates. We recently identified novel histone-free regions (HFRs) that can act as chromatin boundary elements demarcating successive murine Hox genes and help regulate their precise expression domains (Srivastava et al., 2013). In this report, we describe in detail the ChIP-chip analysis strategy associated with the identification of these HFRs. We also provide the Perl scripts for HFR extraction and quality control analysis for this custom designed tiling array dataset.
