The replacement histone H2A.Z in a hyperacetylated form is a feature of active genes in the chicken [PDF]
, 2005 The replacement histone H2A.Z is variously reported as being linked to gene expression and preventing the spread of heterochromatin in yeast, or concentrated at heterochromatin in mammals.

De Novo Polycomb Recruitment: Lessons from Latent Herpesviruses
Viruses, 2021 The Human Herpesviruses persist in the form of a latent infection in specialized cell types. During latency, the herpesvirus genomes associate with cellular histone proteins and the viral lytic genes assemble into transcriptionally repressive ...

DNA methylation dynamics in aging: How far are we from understanding the mechanisms? [PDF]
, 2018 DNA methylation is currently the most promising molecular marker for monitoring aging and predicting life expectancy. However, the mechanisms underlying age-related DNA methylation changes remain mostly undiscovered.Here we discuss the current knowledge ...

Mediator directs co-transcriptional heterochromatin assembly by RNA interference-dependent and -independent pathways. [PDF]
PLoS Genetics, 2013 Heterochromatin at the pericentromeric repeats in fission yeast is assembled and spread by an RNAi-dependent mechanism, which is coupled with the transcription of non-coding RNA from the repeats by RNA polymerase II. In addition, Rrp6, a component of the

Accessibility of promoter DNA is not the primary determinant of chromatin-mediated gene regulation [PDF]
, 2019 DNA accessibility is thought to be of major importance in regulating gene expression. We test this hypothesis using a restriction enzyme as a probe of chromatin structure and as a proxy for transcription factors.
