Matrix Rigidity Mechanoprimes Microglia for Inflammation Through Cytoskeletal‐to‐Nuclear Signaling and 3D Spatio‐Epigenomic Remodeling

Advanced Science, EarlyView.
Pathological tissue rigidity mechanoprimes microglia by enhancing actin cytoskeleton–nucleus coupling and chromatin opening at rigidity‐responsive cis‐regulatory elements (mechanoCREs). Subsequent NF‐κB/p65 signaling converges on this permissive regulatory state to amplify inflammatory gene expression and microglial activation.

Repressive and non-repressive chromatin at native telomeres in Saccharomyces cerevisiae [PDF]

, 2009
Background In Saccharomyces cerevisiae genes that are located close to a telomere can become transcriptionally repressed by an epigenetic process known as telomere position effect.

Cell cycle dependent methylation of Dam1 contributes to kinetochore integrity and faithful chromosome segregation.

PLoS Genetics
The kinetochore, a megadalton structure composed of centromeric (CEN) DNA and protein complexes, is required for faithful chromosome segregation in eukaryotes.

CHD8‐Dependent Chromatin Licensing Sustains Trophoblast Stem Cell Transcriptional Programs

Advanced Science, EarlyView.
In this study, Huang et al., identify chromatin remodeler CHD8 as an essential factor in TSC maintenance and placental development. CHD8‐dependent chromatin accessibility supports the occupancy of key trophoblast TFs and is coupled to KMT2A‐associated H3K4me3 deposition at TSC stem and cell cycle genes, providing a permissive chromatin environment for ...

Plant Metabolites Screening Identifies 7‐epi‐10‐Deacetyltaxol Inhibiting Cell Division by Interfering With the Cell Cycle and Microtubule Organization

Advanced Science, EarlyView.
In this study, an efficient screening system is developed for plant metabolites to find a compound, 7‐epi‐10‐deacetyltaxol, inhibits tissue elongation. It suppresses plant growth through brassinosteroid and microtubule pathways. It is later applied to animal cells and human tumor organoids, resulting in similar cell division suppression. These findings

3D chromatin maps of a brown alga reveal U/V sex chromosome spatial organization

Nature Communications
Nuclear three dimensional (3D) folding of chromatin structure has been linked to gene expression regulation and correct developmental programs, but little is known about the 3D architecture of sex chromosomes within the nucleus, and how that impacts ...

Aspirin‐Derived Salicyl‐CoA Drives Histone Lysine Salicylation Regulated by CBP and SIRT2

Advanced Science, EarlyView.
Aspirin‐derived salicyl‐CoA serves as a previously unrecognized acyl donor for protein lysine salicylation. This study identifies histone lysine salicylation as a reversible epigenetic modification regulated by CBP and SIRT2, expanding the biochemical actions of aspirin beyond its canonical acetylation‐dependent mechanisms and providing a new framework

H3 K36 Methylation Helps Determine the Timing of Cdc45 Association with Replication Origins [PDF]

, 2009
BackgroundReplication origins fire at different times during S-phase. Such timing is determined by the chromosomal context, which includes the activity of nearby genes, telomeric position effects and chromatin structure, such as the acetylation state of ...

Effect of irinotecan on HMGB1, MMP9 expression, cell cycle, and cell growth in breast cancer (MCF-7) cells

Tumor Biology, 2017
Irinotecan is a natural alkaloid agent widely used in cancer therapy. High-mobility group protein B1 as a non-histone chromosomal protein plays a fundamental role in gene expression and inflammation.

Epigenetic Silencing of CYYR1 Promotes Lung Adenocarcinoma Progression Through TRIM21‐Dependent Regulation of HMMR Stability

Advanced Science, EarlyView.
CYYR1 as an epigenetically dysregulated tumor‐suppressive factor that influences oncoprotein stability through TRIM21‐dependent HMMR regulation and reveals a potential therapeutic vulnerability in CYYR1‐deficient LUAD. The graphical illustration was created using FigDraw (www.figdraw.com).
