Euchromatin and Pericentromeric Heterochromatin: Comparative Composition in the Tomato Genome [PDF]
Genetics, 2006 Abstract Eleven sequenced BACs were annotated and localized via FISH to tomato pachytene chromosomes providing the first global insights into the compositional differences of euchromatin and pericentromeric heterochromatin in this model dicot species.

Current Analytical Strategies in Studying Chromatin-Associated-Proteome (Chromatome)
Molecules, 2021 Chromatin is a dynamic structure comprising of DNA and proteins. Its unique nature not only help to pack the DNA tightly within the cell but also is pivotal in regulating gene expression DNA replication.

Transcription establishes microenvironments that organize euchromatin [PDF]
bioRxiv, 2017 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.

Genome Biology, 2022 Background Interactions of chromatin with the nuclear lamina via lamina-associated domains (LADs) confer structural stability to the genome. The dynamics of positioning of LADs during differentiation, and how LADs impinge on developmental gene expression,

The hierarchical packing of euchromatin domains can be described as multiplicative cascades.
PLoS Computational Biology, 2021 The genome is packed into the cell nucleus in the form of chromatin. Biochemical approaches have revealed that chromatin is packed within domains, which group into larger domains, and so forth.

Phosphorylated Lamins in Euchromatin: New Clues to Progeria [PDF]
Developmental Cell, 2020 Lamin proteins not only form the nuclear lamina, but some are also found in the nuclear interior. In this issue of Developmental Cell, Ikegami et al. describe that phosphorylated Lamin C in the nuclear interior interacts with enhancer-like elements and link this to deregulated transcription in progeria.

Pre-implantation mouse embryos cultured In vitro under different oxygen concentrations show altered ultrastructures [PDF]
, 2020 Assisted Reproductive Technologies routinely utilize different culture media and oxygen (O2) concentrations to culture human embryos. Overall, embryos cultured under physiological O2 tension (5%) have improved development compared to embryos cultured ...

Pericentromeric heterochromatin is hierarchically organized and spatially contacts H3K9me2 islands in euchromatin. [PDF]
, 2020 Membraneless pericentromeric heterochromatin (PCH) domains play vital roles in chromosome dynamics and genome stability. However, our current understanding of 3D genome organization does not include PCH domains because of technical challenges associated ...
