SUV39 SET domains mediate crosstalk of heterochromatic histone marks

open access: yeseLife, 2021
The SUV39 class of methyltransferase enzymes deposits histone H3 lysine 9 di- and trimethylation (H3K9me2/3), the hallmark of constitutive heterochromatin.

Quantitative analysis of chromatin compaction in living cells using FLIM-FRET [PDF]

open access: yes, 2009
FRET analysis of cell lines expressing fluorescently tagged histones on separate nucleosomes demonstrates that variations in chromosome compaction occur during ...

Candida albicans repetitive elements display epigenetic diversity and plasticity [PDF]

open access: yes, 2016
Transcriptionally silent heterochromatin is associated with repetitive DNA. It is poorly understood whether and how heterochromatin differs between different organisms and whether its structure can be remodelled in response to environmental signals. Here,

Epigenetic plasticity safeguards heterochromatin configuration in mammals

open access: yesNucleic Acids Research, 2023
Heterochromatin is a key architectural feature of eukaryotic chromosomes critical for cell type-specific gene expression and genome stability. In the mammalian nucleus, heterochromatin segregates from transcriptionally active genomic regions and exists ...

CHROMOSOMAL POLYMORPHISMS OF CONSTITUTIVE HETEROCHROMATIN AND INVERSIONS IN DROSOPHILA [PDF]

open access: yesGenetics, 1977
ABSTRACT A simple technique for preparing mitotic metaphases from a larval ganglion of Drosophila is described. Parallel examination of polytene and metaphase chromosome groups shows that inversion polymorphism in chromosome 3 of D.

Karyotype, C-and fluorescence banding pattern, NOR location and FISH study of five Scarabaeidae (Coleoptera) species

open access: yesGenetics and Molecular Biology, 2005
Meiotic chromosomes obtained from members of the coleopteran subfamilies Rutelinae and Dynastinae were studied using standard and silver nitrate staining, C-banding, base-specific fluorochromes and fluorescent in situ hybridization (FISH).

Constitutive heterochromatin reorganization during somatic cell reprogramming [PDF]

open access: yesThe EMBO Journal, 2011
Induced pluripotent stem (iPS) cell reprogramming is a gradual epigenetic process that reactivates the pluripotent transcriptional network by erasing and establishing repressive epigenetic marks. In contrast to loci-specific epigenetic changes, heterochromatin domains undergo epigenetic resetting during the reprogramming process, but the effect on the ...

Distribution of chromosome 18 and X centric heterochromatin in the interphase nucleus of cultured human cells [PDF]

open access: yes, 1990
In situ hybridization of human chromosome 18 and X-specific alphoid DNA-probes was performed in combination with three dimensional (3D) and two dimensional (2D) image analysis to study the interphase distribution of the centric heterochromatin (18c and ...

Pericentromeric heterochromatin is hierarchically organized and spatially contacts H3K9me2 islands in euchromatin. [PDF]

open access: yes, 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 ...
