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.
