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.

Somatic cell reprogramming for Parkinson's disease treatment

Ibrain, Volume 11, Issue 1, Page 59-73, Spring 2025.
The fundamental purpose of cell reprogramming to treat Parkinson's disease is to generate dopaminergic neurons (DAN) and do transplantation. There are two ways to accomplish this. One method is to induce cells into induced DA neurons (iDAN) directly or to induce cells into induced pluripotent stem cells and ultimately into iDAN in vitro. Another option

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.

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 ...

DNA Methylation and Transcriptomic Profiles of Wilms Tumour Reveal New Deregulated Genes and Epigenetic Processes Relevant for Tumour Stratification and Management

International Journal of Cancer, EarlyView.
ABSTRACT Wilms Tumour (WT), the most common kidney cancer in children, presents features of altered kidney development and frequently exhibits molecular alterations at the 11p15.5 imprinted locus, affecting the IGF2 and H19 genes, which contribute to tumour growth and predisposition.

Strategies and mechanisms of precision genome engineering: From gene editing to genome writing

iMetaOmics, EarlyView.
In this review, we examined the progression of genome manipulation from stochastic nuclease‐mediated cutting toward precise editing and programmable genome writing. We discussed tools like multi‐kilobase RNA‐guided integrators and Artificial Intelligence (AI)‐designed effectors and showed how these advances enable researchers to treat genomes as ...

Hyperoside alleviates endometrial stromal cell senescence in unexplained recurrent spontaneous abortion via DHX9‐mediated R‐loop resolution

iMeta, EarlyView.
This study suggests that the food‐derived flavonoid hyperoside may act as a natural DExH‐box helicase 9 (DHX9) modulator, directly targeting Thr419 of DHX9 to help resolve pathological R‐loop accumulation. Consequently, it suppresses cyclic GMP‐AMP synthase‐stimulator of interferon genes (cGAS‐STING)‐driven endometrial stromal senescence and restores ...

Transcriptional Scaffolds for Heterochromatin Assembly [PDF]

, 2009
Heterochromatin is dynamically regulated during the cell cycle and in response to developmental signals. Recent findings from diverse systems suggest an extensive role for transcription in the assembly of heterochromatin, highlighting the emerging theme ...

High-resolution mapping of heterochromatin redistribution in a Drosophila position-effect variegation model

Epigenetics & Chromatin, 2009
Background Position-effect variegation (PEV) is the stochastic transcriptional silencing of a gene positioned adjacent to heterochromatin. white-mottled X-chromosomal inversions in Drosophila are classic PEV models that show variegation of the eye color ...
