Properties of Chromatin in Human Cells as Characteristics of the State of Human Organism: A Review [PDF]

open access: yesAdv Complement Alt Med. 1(1). ACAM.000505. 2018. http://crimsonpublishers.com/acam/volume1-issue1-acam.php, 2018
The state of chromatin in individual cells is directly related to the state of the whole organism and may be used for assessment of the state of the whole organism. Many hereditary diseases are connected with chromatin rearrangements. Chromatin distribution in cell nucleus is an important characteristic which may be applied for determination of disease

Karyotype evolution in progress: A new diploid number in Belostoma candidulum (Heteroptera: Belostomatidae) from Argentina leading to new insights into its ecology and evolution [PDF]

open access: yes, 2014
A novel chromosome complement (2n = 14 = 12 + XY/XX; male/female sex chromosomes), male meiosis behaviour, heterochromatin characterization, and frequency and distribution of chiasmata are described for the first time in specimens from a natural ...

The Antiviral Activity of Polyphenols

open access: yesMolecular Nutrition &Food Research, EarlyView.
Polyphenols demonstrate remarkable antiviral properties by effectively disrupting multiple biochemical processes essential for viral replication. ABSTRACT Polyphenols are secondary metabolites produced by a large variety of plants. These compounds that comprise the class of phenolic acids, stilbenes, lignans, coumarins, flavonoids, and tannins have a ...

Integrative genomics analysis identifies pericentromeric regions of human chromosomes affecting patterns of inter-chromosomal interactions [PDF]

open access: yesarXiv, 2014
Genome-wide analysis of distributions of densities of long-range interactions of human chromosomes with each other, nucleoli, nuclear lamina, and binding sites of chromatin state regulatory proteins, CTCF and STAT1, identifies non-random highly correlated patterns of density distributions along the chromosome length for all these features.

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 ...

Key Regulators of Parasite Biology Viewed Through a Post‐Translational Modification Repertoire

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Parasites are the leading causes of morbidity and mortality in both humans and animals, imposing substantial socioeconomic burdens worldwide. Controlling parasitic diseases has become one of the key issues in achieving “One Health”. Most parasites have sophisticated life cycles exhibiting progressive developmental stages, morphologies, and ...

The histone chaperone FACT facilitates heterochromatin spreading by regulating histone turnover and H3K9 methylation states

open access: yesCell Reports, 2021
Summary: Heterochromatin formation requires three distinct steps: nucleation, self-propagation (spreading) along the chromosome, and faithful maintenance after each replication cycle.

The Extremely Low Mechanical Force Generated by Nano‐Pulling Induces Global Changes in the Microtubule Network, Nuclear Morphology, and Chromatin Transcription in Neurons

open access: yesSmall, EarlyView.
Nano‐pulling induces stabilization, reorganization, and reorientation of the microtubule network. The nucleus of stretched cells experiences increased lateral tension, becomes more spherical, and develops surface grooves. At the level of gene expression regulation, changes in nuclear morphology induce global chromatin remodeling, leading to reduced ...

Karyotypes and heterochromatin variation (C-bands) in Melipona species (Hymenoptera, Apidae, Meliponinae)

open access: yesGenetics and Molecular Biology, 1998
We describe the karyotypes of eight bee species of the genus Melipona and compare them in terms of heterochromatin content and location (C-banding technique).

On the Heterogeneity of Heterochromatin

open access: yesCaryologia, 1982
SUMMARY The properties of constitutive heterochromatin so far described, perhaps with the exception of the possibility of being C-banded, are not all common to all the species examined. The use of staining techniques or in vivo treatments makes it possible to demonstrate the existence of a marked heterogeneity of fractions of heterochromatin sometimes ...
