Cohesin and condensin extrude DNA loops in a cell cycle-dependent manner
Loop extrusion by structural maintenance of chromosomes (SMC) complexes has been proposed as a mechanism to organize chromatin in interphase and metaphase. However, the requirements for chromatin organization in these cell cycle phases are different, and

Dynamic chromatin: concerted nucleosome remodelling and acetylation [PDF]
The flexibility of chromatin that enables translation of environmental cues into changes in genome utilisation, relies on a battery of enzymes able to modulate chromatin structure in a highly targeted and regulated manner.

This study identifies ARHGAP5, in addition to the frequently mutated ARHGAP35, as significantly mutated in endometrial cancer. Mutations in both genes co‐occur and are associated with their correlated downregulation. Functional CRISPR studies show that both paralogs regulate similar pathways, including actin cytoskeleton organization.

Alterations in 3D chromatin organization contribute to tumorigenesis of EGFR-amplified glioblastoma
Background: EGFR amplification and/or mutation are found in more than half of the cases with glioblastoma. Yet, the role of chromatin interactions and its regulation of gene expression in EGFR-amplified glioblastoma remains unclear.

Pericentric Chromatin Is Organized into an Intramolecular Loop in Mitosis [PDF]
Cohesin proteins link sister chromatids and provide the basis for tension between bi-oriented sister chomatids in mitosis. Cohesin is concentrated at the centromere region of the chromosome despite the fact that sister centromeres can be separated by 800nm in vivo. The function of cohesin at sites of separated DNA is unknown.

Repair of neuronal DNA damage in Alzheimer's disease by KCL‐286. (A) Amyloid‐β oligomers and plaques impair neuronal DNA repair pathways, leading to DNA double‐strand breaks and glial activation. (B) KCL‐286 activates RARβ/RXR signalling via retinoic acid response elements (RAREs), associated with increased BRCA1 expression, enhanced DNA repair and ...

Model of the CDKN1A chromatin loop molecular switch.
Following activation of CDKN1A by p53 in response to stress, the passage of the transcriptional machinery evicts the cohesin and disrupts the chromatin loop.

RNA-binding proteins (RBPs) play diverse roles in regulating co-transcriptional RNA-processing and chromatin functions, but our knowledge of the repertoire of chromatin-associated RBPs (caRBPs) and their interactions with chromatin remains limited. Here,
