Heterochromatin: On the ADAR Radar? [PDF]
Current Biology, 2005 Vigilin proteins, the absence of which is known to cause abnormalities in heterochromatin, have been found to bind edited RNAs. Molecular complexes including vigilin comprise proteins involved with RNA editing and with DNA repair, making connections between these processes and RNA-based silencing mechanisms.

C-banding, fluorescent staining and NOR location in holokinetic chromosomes of bugs of the Neotropical genus Antiteuchus (Heteroptera: Pentatomidae: Discocephalinae) [PDF]
, 2006 Different cytogenetic techniques including C-banding, base-specific fluorochromes and silver nitrate staining were used to compare the karyotypes of three species of bugs, representatives of the Neotropical genus Antiteuchus, namely A.

Proceedings of the National Academy of Sciences of the United States of America, 2021 Significance In multicellular organisms, a single genome gives rise to a multitude of cell types by enforcing appropriate gene expression patterns. Epigenetic mechanisms involving modification of histones, including tri-methylation of histone H3 lysine 9

Genome mapping and characterization of the
BMC Genomics, 2010 Background Heterochromatin plays an important role in chromosome function and gene regulation. Despite the availability of polytene chromosomes and genome sequence, the heterochromatin of the major malaria vector Anopheles gambiae has not been mapped and

Heterochromatin formation promotes longevity and represses ribosomal RNA synthesis. [PDF]
PLoS Genetics, 2012 Organismal aging is influenced by a multitude of intrinsic and extrinsic factors, and heterochromatin loss has been proposed to be one of the causes of aging. However, the role of heterochromatin in animal aging has been controversial.

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 ...

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.

Genome Research, 2021 Heterochromatin remodeling is critical for various cell processes. In particular, the “loss of heterochromatin” phenotype in cellular senescence is associated with the process of aging and age-related disorders. Although biological processes of senescent
