Budding Yeast Wapl Controls Sister Chromatid Cohesion Maintenance and Chromosome Condensation [PDF]

Current Biology, 2013
The establishment of stable sister chromatid cohesion during DNA replication requires acetylation of the chromosomal cohesin complex by the replication fork-associated acetyltransferase Eco1. Cohesin acetylation is thought to facilitate replication fork progression by counteracting an as yet ill-defined cohesion "antiestablishment" activity imposed by ...

Early detection of plant community responses to climate warming along mountain roads

Journal of Ecology, Volume 113, Issue 9, Page 2575-2589, September 2025.
Plants are rapidly shifting to higher elevations along mountain roads in Switzerland. These shifts result in a significant community warming of 0.13°C within 10 years. However, because species gained or lost in communities tend to have low cover, this signal is only detectable in unweighted estimates of community‐inferred temperatures—highlighting the ...

In Favor of Establishment: Regulation of Chromatid Cohesion in Plants

Frontiers in Plant Science, 2017
In eukaryotic organisms, the correct regulation of sister chromatid cohesion, whereby sister chromatids are paired and held together, is essential for accurate segregation of the sister chromatids and homologous chromosomes into daughter cells during ...

Non-redundant roles in sister chromatid cohesion of the DNA helicase DDX11 and the SMC3 acetyl transferases ESCO1 and ESCO2.

PLoS ONE, 2020
In a process linked to DNA replication, duplicated chromosomes are entrapped in large, circular cohesin complexes and functional sister chromatid cohesion (SCC) is established by acetylation of the SMC3 cohesin subunit.

EBV Latency Programs: Molecular and Epigenetic Regulation and Its Role in Disease Pathogenesis

Journal of Medical Virology, Volume 97, Issue 7, July 2025.
ABSTRACT Epstein‐Barr virus (EBV) asymptomatically infects over 95% of the global population, and poses a great threat to human health. This review summarizes the complex mechanisms underlying EBV latency programs and their roles in both viral persistence and disease development.

Effect of benzo[a]pyrene exposure during pregnancy on learning and memory functions of rat offspring and expression levels of related genes

环境与职业医学
BackgroundPolycyclic aromatic hydrocarbons represented by benzo[a]pyrene are among the most significant occupational and environmental pollutants. Exposure to benzo[a]pyrene during pregnancy can cause delayed intellectual development in offspring, and ...

Migration of Deep Convection Center in Subpolar North Atlantic Around 6 ka Suggested by a Dinocyst Proxy of Mixed Layer Depth

Paleoceanography and Paleoclimatology, Volume 40, Issue 6, June 2025.
Abstract This study explores the relationship between dinoflagellate cyst (dinocyst) assemblages and the mixed layer depth (MLD) using canonical correspondence analyses. Our results suggest that wintertime deepening of MLD, in response to deep convection events, can influence dinocyst assemblages and especially the relative abundance of ...

Absolute quantification of cohesin, CTCF and their regulators in human cells

eLife, 2019
The organisation of mammalian genomes into loops and topologically associating domains (TADs) contributes to chromatin structure, gene expression and recombination. TADs and many loops are formed by cohesin and positioned by CTCF. In proliferating cells,

Current Advances in Genome Modeling Across Length Scales

WIREs Computational Molecular Science, Volume 15, Issue 3, May/June 2025.
ABSTRACT The physical organization of DNA within the nucleus is fundamental to a wide range of biological processes. The experimental investigation of the structure of genomic DNA remains challenging due to its large size and hierarchical arrangement. These challenges present considerable opportunities for combined experimental and modeling approaches.
