ID3 deficiency alters chromatin accessibility at DSB sites and enhances vulnerability to HDAC inhibition

open access: yesInternational Journal of Cancer, Volume 158, Issue 12, Page 3173-3186, 15 June 2026.
What's new? Errors in DNA double‐strand break (DSB) repair can lead to mutations, chromosomal instability, and ultimately cancer. Inhibitor of DNA‐binding 3 (ID3), a transcriptional repressor, is crucial to promoting DSB repair and helping maintain genome stability. Here, the authors investigated ID3 regulation of DNA repair via chromatin accessibility

Regulation of Sister Chromatid Cohesion between Chromosome Arms [PDF]

open access: yesCurrent Biology, 2004
Sister chromatid separation in anaphase depends on the removal of cohesin complexes from chromosomes. In vertebrates, the bulk of cohesin is already removed from chromosome arms during prophase and prometaphase, whereas cohesin remains at centromeres until metaphase, when cohesin is cleaved by the protease separase. In unperturbed mitoses, arm cohesion

The Polymers of Life: Exploring Cellular Function Through Polymer Concepts

open access: yesAdvanced Science, Volume 13, Issue 33, 15 June 2026.
Biomolecular phase separation reveals that a hidden layer of cellular organization is governed by the principles of polymer science. This review bridges polymer physics and cell biology, offering a primer on fundamental concepts, proposing a framework for interrogating cellular function, and synthesizing biophysical methods for decoding macromolecular ...

The chromosomal association of the Smc5/6 complex depends on cohesion and predicts the level of sister chromatid entanglement.

open access: yesPLoS Genetics, 2014
The cohesin complex, which is essential for sister chromatid cohesion and chromosome segregation, also inhibits resolution of sister chromatid intertwinings (SCIs) by the topoisomerase Top2. The cohesin-related Smc5/6 complex (Smc5/6) instead accumulates

Evolutionary Patterns of the Genes Involved in the Integrity and Segregation of Chromosomes in Sawflies (Hymenoptera: Symphyta)

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
This study identifies and characterizes the genes encoding cohesin and condensin complexes across Symphytan superfamilies, revealing their structural and functional roles with conserved motifs in maintaining genome stability. Phylogenetic analyses indicate that SMC genes originated from ancient duplication events, with notable gene loss (e.g., CAPG2 ...

Pitfalls and missing links in current understanding of 4D genomes

open access: yesQuantitative Biology, Volume 14, Issue 2, June 2026.
Abstract The spatial and temporal organization of the genome—collectively termed the 4D genome—is pivotal for regulating gene expression, maintaining genome stability, and guiding development. The convergence of chromosome conformation capture technologies, super‐resolution microscopy, and single‐cell epigenomics has transformed our understanding of ...

Chl1 DNA helicase and Scc2 function in chromosome condensation through cohesin deposition.

open access: yesPLoS ONE, 2017
Chl1 DNA helicase promotes sister chromatid cohesion and associates with both the cohesion establishment acetyltransferase Eco1/Ctf7 and the DNA polymerase processivity factor PCNA that supports Eco1/Ctf7 function.

From Mesenchymal Stromal Cells to Extracellular Vesicles: Scalable Strategies for Ovarian Stroma Regeneration

open access: yesMolecular Reproduction and Development, Volume 93, Issue 5, May 2026.
ABSTRACT Ovarian aging is characterized by the reduction of the follicular pool and a progressive loss in oocyte quality. Although these changes have initially been attributed to oocyte alterations, increasing evidence indicates that stromal deterioration plays a central role in this process.

Spatiotemporal regulation of Aurora B recruitment ensures release of cohesion during C. elegans oocyte meiosis

open access: yesNature Communications, 2018
During meiosis, step-wise release of sister chromatid cohesion mediated by REC-8 cohesin is required for the formation of haploid gametes. Here, the authors show that in C.

Age‐Dependent Alterations of Chromosomal Passenger Complex Members During Implantation and Decidualization in the Mouse Uterus

open access: yesAging Cell, Volume 25, Issue 5, May 2026.
Aging in females reduces the number of implantation sites and leads to specific, compartment‐dependent changes in components of the chromosomal passenger complex (pIncenp, Aurora B, Survivin, Borealin) during mouse uterine implantation and decidualization.
