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

Adv 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

Nuclear Translocation of S100A9 Triggers Senescence of Human Amnion Fibroblasts by De‐Repressing LINE1 Via Heterochromatin Erosion at Parturition

Advanced Science, Volume 12, Issue 21, June 5, 2025.
This study shows that the classical secretory protein S100 calcium‐binding protein A9 (S100A9) can translocate to the nucleus upon de‐phosphorylation at Thr 113 in human amnion fibroblasts at parturition, where S100A9 induces heterochromatin erosion through segregation of the heterochromatin maintenance protein, resulting inLong Interspersed Nuclear ...

Distribution of constitutive heterochromatin in Triatoma melanocephala (Hemiptera, Triatominae)

Genetics and Molecular Research, 2014
In principle, Triatoma melanocephala was included in the Brasiliensis subcomplex on the basis of morphological parameters and geographical layout, since there were no other relevant data available in the literature. On the basis of karyotype, it has been proposed to exclude T. melanocephala, as well as of T. vitticeps and T.

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

arXiv, 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.

MeCP2 Lactylation Protects against Ischemic Brain Injury by Transcriptionally Regulating Neuronal Apoptosis

Advanced Science, Volume 12, Issue 21, June 5, 2025.
MeCP2 lactylation protects against ischemic stroke by reducing brain infarct volume and improving neurological outcomes. Lactylation at K210/K249 exerts neuroprotective effects by repressing the transcription of apoptosis‐associated genes, including Pdcd4 and Pla2g6. HDAC3 and p300 serve as key regulatory enzymes for MeCP2 lactylation following stroke.

Chromosome banding of two Litoria species (Anura, Hylidae) [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2013
This research was the first cytogenetic studies of green-eyed tree frog (Litoria genimaculata) and Nyakala frog(L. nyakalensis). The mitotic chromosomes were prepared directly from bone marrow after in vivo colchicine treatment andanalysed following ...

Somatic Pairing in Drosophila virilis Mitosis [PDF]

, 1975
In neuroblast cells homologous chromosomes tend to pair during prophase of mitosis. Heterochromatic elements of homologous chromosomes are widely separated in very early prophase, at which time the euchromatin is poorly stained.
