Lamin B1 mapping reveals the existence of dynamic and functional euchromatin lamin B1 domains
Lamina-associated domains (LADs) contact lamins in the nuclear lamina, and lamin B1 was thought to bind heterochromatic regions at the nuclear envelope.

Satellite DNAs are tandemly repeated sequences clustered within heterochromatin. However, in some cases, such as the major TCAST1 satellite DNA from the beetle Tribolium castaneum, they are found partially dispersed within euchromatin.

Intra-Chromosomal Potentials from Nucleosomal Positioning Data [PDF]
No systematic method exists to derive intra-chromosomal potentials between nucleosomes along a chromosome consistently across a given genome. Such potentials can yield information on nucleosomal ordering, thermal as well as mechanical properties of chromosomes.

DNA, NYS and DNFB protein contents were measured cytophotometrically using the Feulgen method in the nuclei of the epidermis from. the basal zone of young leaves and from the basal and apical zones of old leaves in two perennial monocotyledonous species,

Nuclear dynamics of radiation-induced foci in euchromatin and heterochromatin [PDF]
Repair of double strand breaks (DSBs) is essential for cell survival and genome integrity. While much is known about the molecular mechanisms involved in DSB repair and checkpoint activation, the roles of nuclear dynamics of radiation-induced foci (RIF) in DNA repair are just beginning to emerge.

Protocol for detecting chromatin dynamics and screening chromatin relaxer by FRAP assay
Summary: We describe a fluorescence recovery after photobleaching (FRAP) protocol for assessing the dynamics of heterochromatin/euchromatin and identifying chromatin relaxers for cell fate transition.

RNAi-mediated positive feedback loops are pivotal for the maintenance of heterochromatin, but how they are downregulated at heterochromatin-euchromatin borders is not well understood.

Euchromatin Activity Enhances Segregation and Compaction of Heterochromatin in the Cell Nucleus
The large-scale organization of the genome inside the cell nucleus is critical for the cell’s function. Chromatin—the functional form of DNA in cells—serves as a template for active nuclear processes such as transcription, replication, and DNA repair ...

Differential DNA lesion formation and repair in heterochromatin and euchromatin [PDF]
Discretely orchestrated chromatin condensation is important for chromosome protection from DNA damage. However, it is still unclear how different chromatin states affect the formation and repair of nucleotide excision repair (NER) substrates, e.g.

Transcription organizes euchromatin similar to an active microemulsion [PDF]
Chromatin is organized into heterochromatin, which is transcriptionally inactive, and euchromatin, which can switch between transcriptionally active and inactive states. This switch in euchromatin activity is accompanied by changes in its spatial distribution. How euchromatin rearrangements are established is unknown.
