L. Hannibal, Roberta B. Chuong, Edward Carlos Rivera-Mulia, Juan M. Gilbert, David Valouev, Anton C. Baker, Julie UR domains are heterochromatic. <p><b>A</b>. UR domains correlate with histone marks. Screen shot from the UCSC genome browser of the last half of chromosome 14 (schematic shown above screen shot) showing the following: 3SEQ from <i>in vivo</i> e9.5 TGCs and <i>in vitro</i> d7 TGCs (black), active histone marks (H3K27ac, H3K4me1, H3K4me3; dark purple) and repressive histone marks (H3K9me3, H3K27me3; orange) for cultured TS cells and TGCs, and aCGH and WGS data from <i>in vivo</i> e9.5 TGCs (pink/red). Histone mark mean is darker color, maximum is lighter color. UR domains boxed in pink. <b>B</b>. UR domains are a subset of heterochromatin in TS cells. The Pearson correlation (R) between NLog2 values of TGC vs. embryo (WGS) and fold enrichment (FE) for histone marks. Data points represent 1 Mb windows in the genome. UR domains (negative NLog2 values) are correlated with high values for repressive histone marks (negative R values). UR domains (negative NLog2 values) are negatively correlated with high values for active histone marks (positive R values). Red lines represent the lowess line (locally weighted scatterplot smoothing) of the data points. UR domains boxed in pink. <b>C</b>. UR domains are a subset of heterochromatin in TGCs.
