C-banding, fluorescent staining and NOR location in holokinetic chromosomes of bugs of the Neotropical genus Antiteuchus (Heteroptera: Pentatomidae: Discocephalinae) [PDF]

, 2006
Different cytogenetic techniques including C-banding, base-specific fluorochromes and silver nitrate staining were used to compare the karyotypes of three species of bugs, representatives of the Neotropical genus Antiteuchus, namely A.

Seipin deficiency increases chromocenter fragmentation and disrupts acrosome formation leading to male infertility [PDF]

Cell Death & Disease, 2015
AbstractThe Berardinelli–Seip congenital lipodystrophy type 2 (Bscl2, seipin) gene is involved in adipogenesis. Bscl2−/− males were infertile but had normal mating behavior. Both Bscl2−/− cauda epididymis sperm count and sperm motility were ~20 × less than control.

Structure and function of centromeric and pericentromeric heterochromatin in Arabidopsis thaliana

Frontiers in Plant Science, 2015
The centromere is a specific chromosomal region where the kinetochore assembles to ensure the faithful segregation of sister chromatids during mitosis and meiosis. Centromeres are defined by a local enrichment of the specific histone variant CenH3 mostly

Nejire/dCBP-mediated control of H3 acetylation and transcriptional regulation by testis-specific Plus3 domain proteins during Drosophila spermatogenesis [PDF]

, 2018
Spermatogenesis describes the development from germ line stem cells to highly specialized sperm. Drosophila melanogaster spermatogenesis is a good model system for chromatin remodelling processes as many of these processes are similar in mammals and in ...

Characterization of the Drosophila group ortholog to the amino-terminus of the alpha-thalassemia and mental retardation X-Linked (ATRX) vertebrate protein. [PDF]

PLoS ONE, 2014
The human ATRX gene encodes hATRX, a chromatin-remodeling protein harboring an helicase/ATPase and ADD domains. The ADD domain has two zinc fingers that bind to histone tails and mediate hATRX binding to chromatin.

Silencing markers are retained on pericentric heterochromatin during murine primordial germ cell development [PDF]

, 2017
Background: In the nuclei of most mammalian cells, pericentric heterochromatin is characterized by DNA methylation, histone modifications such as H3K9me3 and H4K20me3, and specific binding proteins ...

Chromosome and DNA methylation dynamics during meiosis in autotetraploid Arabidopsis arenosa [PDF]

, 2010
Variation in chromosome number due to polyploidy can seriously compromise meiotic stability. In autopolyploids, the presence of more than two homologous chromosomes may result in complex pairing patterns and subsequent anomalous chromosome ...

Role of dynamic nuclear deformation on genomic architecture reorganization.

PLoS Computational Biology, 2019
Higher-order genomic architecture varies according to cell type and changes dramatically during differentiation. One of the remarkable examples of spatial genomic reorganization is the rod photoreceptor cell differentiation in nocturnal mammals.

Low YTHDC1 Expression Upregulates FSCN1 to Promote Nuclear F‐Actin Formation and Facilitate Double‐strand DNA Breaks Repair in TMZ‐Resistant Glioblastoma

Advanced Science, Volume 13, Issue 13, 3 March 2026.
This study revealed that low expression of YTHDC1 in TMZ‐resistant GBM cells leads to increased FSCN1 expression, which is suppressed by m6A modification. FSCN1 activates the CDC42/N‐WASP/Arp2/3 axis in the cell nucleus by recruiting the guanine nucleotide exchange factor (GEF) family member FGD1, thereby promoting F‐actin polymerization in the nucleus.

Polyploidy and the Cellular and Areal Diversity of Rat Cortical Layer 5 Pyramidal Neurons

Cell Reports, 2017
In many species, polyploidy, in which an increase in nuclear DNA content is accompanied by an increase in cell size, contributes to cellular diversity.
