Chromatin is highly organized within discrete chromosome territories, into compartments of active or inactive chromatin, self-interacting domains, and loops between specific loci (reviewed in refs. 1,2). However, the relationship between the three-dimensional (3D) organization of chromatin and the regu...
3b). Significant cis-meQTL SNPs were mostly found within 100 kb of target DMPs (Fig. 3c), and those DMPs were more likely to be enriched in kidney enhancer regions (OR = 6.99, P = 9.0×10−14), overall suggesting that the observed methylation changes are strongly impacted ...
the nucleosome, is composed of DNA wrapped around the histone octamer made of a H3/H4 tetramer flanked by two H2A/H2B dimers. A fifth histone called the H1 linker also participates in the chromatin structure. Chromatin enables DNA compaction within the constraint of nuclear space. Besides this ...
A special iteration procedure is developed to find if there are phase relationships between different periodically repeating dinucleotides of chromatin DNA. A very specific symmetrical pattern of preferences of different dinucleotides to certain positions within a repeating 10.5 base frame is indeed found....
Linker DNA was found to be critical for the specific docking of ISW2 with nucleosomes as shown by mapping the physical contacts of ISW2 with nucleosomes at base-pair resolution. Hydroxyl radical footprinting revealed that ISW2 not only extensively interacts with the linker DNA, but also approach...
steps to detectDNA modificationsorhistonemodifications, our approach is fast, cheap and robust. By coupling cell separation, chromatinpurificationand epigenetic mark quantification, we demonstrate a facile approach where the whole operation can be accomplished within 8h, which otherwise would take 2–3 ...
Treatment with prom-A siRNA induced enrichment of H3K9me2 not only at the targeted site within the promoter region but also well upstream in the U3 region and well downstream into the coding region of the genome. HDAC1 is enriched throughout the promoter region but not in the coding region....

We validated the prediction results in the ENCODE regions by calculating how many predicted promoters are supported by annotated TSSs in RefSeq. The adjacent 3 log-odds (1, 2) are averaged. If multiple peaks of promoters or enhancers are found within 1.5 kb, only the highest log-odd is sele...
However, many genes are also found in regions of closed chromatin structure. This raised the question as to why would genes be maintained in closed chromatin if this meant they were simply less accessible for transcription. One possibility is that they need to be subject to especially tight ...
