Abstract

Nucleosomes "talk" to each other about their modification state to form extended domains of modified histones independently of the underlying DNA sequence. At the same time, DNA elements promote modification of nucleosomes in their vicinity. How do these site-specific and histone-based activities act together to regulate spreading of histone modifications along the genome? How do they enable epigenetic memory to preserve cell identity? Many models for the dynamics of repressive histone modifications emphasize the role of strong positive feedback loops, which reinforce histone modifications by recruiting histone modifiers to preexisting modifications. Recent experiments question that repressive histone modifications are self-sustained independently of their genomic context, thereby indicating that histone-based feedback is relatively weak. In the present review, current models for the dynamics of histone modifications are compared and it is suggested that limitation of histone-based feedback is key to intrinsic confinement of spreading and coexistence of short- and long-term memory at different genomic loci.

Attention Score in Context

This research output has an Altmetric Attention Score of 11. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 13 November 2017.
All research outputs
#1,073,559
of 11,350,788 outputs
Outputs from BioEssays
#238
of 2,021 outputs
Outputs of similar age
#44,110
of 266,305 outputs
Outputs of similar age from BioEssays
#13
of 40 outputs
Altmetric has tracked 11,350,788 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 90th percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 2,021 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.4. This one has done well, scoring higher than 88% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 266,305 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 83% of its contemporaries.
We're also able to compare this research output to 40 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 67% of its contemporaries.
