And that honor was probably the king, because if South had the singleton king, he surely would have led it at Trick 2. So West was marked with both red aces.
This pattern of repressed genes being marked with both H3K27 and H3K4 trimethylation, which we also observed on the p16INK4A promoter [11], is termed a 'bivalent' or 'poised' chromatin domain and has been identified in association with developmentally regulated genes in embryonic stem cells [60].
H3K27me3, however, marks silenced genes, and appears to be dominant over other activating marks; genes that are marked with both K3K27me3 and H3K4me3 are typically silent.
SOX11 has been shown to be regulated by epigenetic events in pluripotent embryonic stem cells and is marked with both activating (H3K4me3) and repressive (H3K27me3) histone marks [ 5].
Specific genomic regions in ES cells are marked with both H3K4me3 and H3K27me3 and are termed "bivalent" domains, which are transcriptionally inactive regions that are poised for transcriptional activation (24).
Recent studies showed that susceptible CGI in several cell types are enriched significantly for targets of polycomb group proteins, which are marked with both active and repressive histone modifications in embryonic stem cells (Teschendorff et al., 2010).
The 60th anniversary of the truce deal that ended the Korean War has been marked with ceremonies in both the North and the South.
For reasons of visibility not all the facets are marked with symbols in both images.
Another set of reports, in which the chromatin profile of ES cells, somatic stem cells and their differentiated progeny were contrasted, provided collective evidence that many developmental regulators genes in ES cells are primed for future expression, being marked with histone modifications associated with both active and repressed chromatin [ 19, 20].
Those products have been a particular annoyance for consumers because they generally are marked with suggested prices for both countries, making for easy comparisons.
