Neurogenesis and the Epigenetic Landscape: Role of Histone Modifications and Chromatin Remodeling

Brain and Behavior, Volume 16, Issue 2, February 2026.
Histone methylation and acetylation modulate gene expression by inducing chromatin condensation or relaxation, which in turn regulates transcriptional activity and impacts neurogenesis. ABSTRACT Aims The purpose of this review is to examine how epigenetic regulation particularly chromatin modification and histone methylation controls gene expression ...

Analysis of the spatial distribution of centromere/chromocenter: results of statistical tests.

, 2013
For F- and G-functions, the table gives the statistic (D) and the p-value of the bilateral Kolmogorov-Smirnov test that was used to assess differences between observed distributions and completely random patterns. The table also gives the statistic (tau)

Generation and characterization of rat and mouse monoclonal antibodies specific for MeCP2 and their use in X-inactivation studies [PDF]

, 2011
Methyl CpG binding protein 2 (MeCP2) binds DNA, and has a preference for methylated CpGs and, hence, in cells, it accumulates in heterochromatin. Even though it is expressed ubiquitously MeCP2 is particularly important during neuronal maturation. This is

Effects of sodium valproate on the chromatin of triatoma infestans (Klug, 1834) (hemiptera, reduviidae) under in vitro culture conditions

, 2021
Sodium valproate (VPA) is a classic anticonvulsive, a histone deacetylase inhibitor, and a chromatin remodeling inducer. When injected into specimens of Triatoma infestans, a vector of Chagas disease, VPA affects the chromatin supraorganization of ...

Comparative Study of Spermatogenesis and Nucleolar Behavior in Testicular Lobes of Euschistus heros (Heteroptera: Pentatomidae)

Psyche: A Journal of Entomology, 2010
In some testicular lobes of the Pentatomidae there may be occurrence of atypical spermatogenesis or polymegaly, leading to the production of nonfertile sperm.

Novel Drosophila Heterochromatin Protein 1 (HP1)/Origin Recognition Complex-associated Protein (HOAP) Repeat Motif in HP1/HOAP Interactions and Chromocenter Associations*

Journal of Biological Chemistry, 2003
Association of the highly conserved heterochromatin protein, HP1, with the specialized chromatin of centromeres and telomeres requires binding to a specific histone H3 modification of methylation on lysine 9.

Zipping up the Synaptonemal Complex: Pathways to Homologous Chromosome Synapsis

BioEssays, Volume 48, Issue 1, January 2026.
The synaptonemal complex (SC) is a conserved protein structure that assembles between homologous chromosomes during meiosis. Here, we review pathways promoting homologous synapsis across model organisms, examining coordination with homolog pairing and recombination, spatiotemporal regulation of SC assembly, and the conserved molecular modules coupling ...

Changes in nuclear phenotypes following cold shock in Panstrongylus megistus (Burmeister)

Memorias do Instituto Oswaldo Cruz, 2000
The nuclear phenotypes of Malpighian tubule epithelial cells of 5th instar male nymphs of the blood-sucking insect Panstrongylus megistus were studied immediately after a short (1 h) cold shock at 0ºC, and 10 and 30 days later.

Karyotyping and Distribution Patterns of Endemic Chinese Lilies: Insights Into Their Conservation Under Climate Change

Ecology and Evolution, Volume 16, Issue 1, January 2026.
This study integrates cytogenetic and ecological analyses of two endemic Chinese alpine lilies, Lilium lophophorum (2n = 24) and L. nanum (2n = 48), to establish a foundational understanding of their chromosomal diversity and distribution patterns. We document substantial intraspecific karyotypic variation in diploid L.
