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.

Insights into organelle forming RNAs: Diversity, functions and future perspectives

Animal Models and Experimental Medicine, EarlyView.
RNA molecules play crucial roles in the formation and maintenance of cellular structures and organelles. These ‘organelle formation RNAs’ include ribosomal RNAs, paraspeckle‐forming RNAs, nuclear speckle‐forming RNAs, nucleolus‐forming RNAs, and cytoskeleton‐forming RNA.

The Emerging Roles of Heterochromatin in Cell Migration

Frontiers in Cell and Developmental Biology, 2020
Cell migration is a key process in health and disease. In the last decade an increasing attention is given to chromatin organization in migrating cells. In various types of cells induction of migration leads to a global increase in heterochromatin levels.

The HSV-1 Latency-Associated Transcript Functions to Repress Latent Phase Lytic Gene Expression and Suppress Virus Reactivation from Latently Infected Neurons [PDF]

, 2016
open access articleHerpes simplex virus 1 (HSV-1) establishes life-long latent infection within sensory neurons, during which viral lytic gene expression is silenced.

Adropin modulates pancreatic cell proliferation and glutathione levels in an animal model of type 1 diabetes mellitus

Animal Models and Experimental Medicine, EarlyView.
Adropin is related to the energy homeostasis‐associated gene. It significantly increased glutathione reductase enzyme levels in the pancreas of experimental diabetic rats. Adropin may reduce the severity of diabetes and its complications. Cell proliferation in the exocrine is reduced after the administration of adropin.

Inheritance of H3K9 methylation regulates genome architecture in Drosophila early embryos

The EMBO Journal
Constitutive heterochromatin is essential for transcriptional silencing and genome integrity. The establishment of constitutive heterochromatin in early embryos and its role in early fruitfly development are unknown. Lysine 9 trimethylation of histone H3

Gene regulation and epigenotype in Friedreich's ataxia [PDF]

, 2008
Friedreich??????s ataxia (FRDA) is known to be provoked by an abnormal GAA-repeat expansion located in the first intron of the FXN gene. As a result of the GAA expansion, patients exhibit low levels of FXN mRNA, leading to FRDA.

Epigenotoxicity: Decoding the epigenetic imprints of genotoxic agents and their implications for regulatory genetic toxicology

Environmental and Molecular Mutagenesis, EarlyView.
Abstract Regulatory genetic toxicology focuses on DNA damage and subsequent gene mutations. However, genotoxic agents can also affect epigenetic marks, and incorporation of epigenetic data into the regulatory framework may thus enhance the accuracy of risk assessment.

H3K27me3 and the PRC1-H2AK119ub pathway cooperatively maintain heterochromatin and transcriptional silencing after the loss of H3K9 methylation

Epigenetics & Chromatin
Background Heterochromatin is a fundamental component of eukaryotic chromosome architecture, crucial for genome stability and cell type-specific gene regulation.
