HMGD1 and H1 density are correlated with distance from DNaseI hypersensitive sites. Box plots show (A) the distribution of HMGD1 and (B) H1 densities calculated from non-overlapping 1 kb regions. The box represents the inter-quartile range of the distribution and the bar represents the median. The whiskers extend to the most extreme data point that is no more than 1.5 times the interquartile range from the box. Regions are grouped by their distance to the nearest DNase I hypersensitive site (DHS). (C) Distributions of HMGD1/H1 ratio for DHS regions less than 2 kb from the nearest annotated TSS.
