Constitutive heterochromatin distribution in pig (Sus scrofa) chromosomes [PDF]
Caryologia, 1998 Constitutive heterochromatin (HC = C-banding) distribution was studied in pig (Sus5crofa) chromosomes from 20 animals belonging to Cinta Senese and Calabrese breeds raised in southern Italy. The use of CBG-banding, sequential GBG/CBA-banding and sequential GBG/ Ag-NOR/CBA-banding techniques allowed more detailed characterization of C-banding patterns ...

The Proteomic Composition and Organization of Constitutive Heterochromatin in Mouse Tissues. [PDF]
CellsPericentric heterochromatin (PCH) forms spatio-temporarily distinct compartments and affects chromosome organization and stability. Albeit some of its components are known, an elucidation of its proteome and how it differs between tissues in vivo is lacking.

Cytologic characterization of human constitutive heterochromatin
, 2000 A study was conducted to cytologically map certain subsets of constitutive heterochromatin onto specific portions of human chromosomes. This involved sequentially staining metaphase chromosomes from lymphocytes first with the Centromeric Dot, Giemsa-11, G-banding or Lateral Asymmetry staining techniques, which are cytochemical methods which stain ...

On the evolution of Yeti, a Drosophila melanogaster heterochromatin gene. [PDF]
PLoS ONE, 2014 Constitutive heterochromatin is a ubiquitous and still unveiled component of eukaryotic genomes, within which it comprises large portions. Although constitutive heterochromatin is generally considered to be transcriptionally silent, it contains a ...

On the relations of phase separation and Hi-C maps to epigenetics [PDF]
Royal Society Open Science, 2020 The relationship between compartmentalization of the genome and epigenetics is long and hoary. In 1928, Heitz defined heterochromatin as the largest differentiated chromatin compartment in eukaryotic nuclei.

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.
