Interaction between Polycomb and SSX Proteins in Pericentromeric Heterochromatin Function and Its Implication in Cancer

Cells, 2020
The stability of pericentromeric heterochromatin is maintained by repressive epigenetic control mechanisms, and failure to maintain this stability may cause severe diseases such as immune deficiency and cancer.

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.

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.

CAF-1 is essential for heterochromatin organization in pluripotent embryonic cells. [PDF]

PLoS Genetics, 2006
During mammalian development, chromatin dynamics and epigenetic marking are important for genome reprogramming. Recent data suggest an important role for the chromatin assembly machinery in this process. To analyze the role of chromatin assembly factor 1

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.

Comprehensive Mapping of Functional Enhancers in Chinese Hamster Ovary Cells

Biotechnology and Bioengineering, EarlyView.
In this study, the authors identified regions with enhancer activity in the CHO cell genome using genome‐wide and targeted STARR‐seq. The analysis revealed thousands of newly identified enhancer sequences, where some of the most active sequences could drive transgene expression at levels similar to or higher than strong viral enhancers.

Chromatin phase separation and nuclear shape fluctuations are correlated in a polymer model of the nucleus

Nucleus
Abnormal cell nuclear shapes are hallmarks of diseases, including progeria, muscular dystrophy, and many cancers. Experiments have shown that disruption of heterochromatin and increases in euchromatin lead to nuclear deformations, such as blebs and ...

Dynamic expression of lamin B1 during adult neurogenesis in the vertebrate brain

Developmental Dynamics, EarlyView.
Abstract Background In mammals, specific brain regions such as the dentate gyrus (DG) of the hippocampus and the subventricular zone (SVZ) of the lateral ventricles harbor adult neural stem/progenitor cells (ANSPCs) that give rise to new neurons and contribute to structural and functional brain plasticity.
