Formation of Chromosomal Domains by Loop Extrusion

Cell Reports, 2016
Topologically associating domains (TADs) are fundamental structural and functional building blocks of human interphase chromosomes, yet the mechanisms of TAD formation remain unclear. Here, we propose that loop extrusion underlies TAD formation.

Dose‐Dependent Reprogramming of Chromatin Accessibility by SOX4 Drives the Transcriptional Response to Iron Overload

Advanced Science, Volume 13, Issue 43, 3 August 2026.
This study demonstrates that iron overload triggers widespread chromatin compaction and transcriptional repression in human granulosa cells, recapitulating features of endometriosis. The epigenetic reprogramming is orchestrated by a TFEB‐SOX4‐SWI/SNF axis, with SOX4 acting as a central, dosage‐sensitive regulator.

Master Regulator SMC1A, Stabilized by N6‐Methyladenosine Reader IGF2BP1, Promotes HCC Progression Through Facilitating Enhancer–Promoter Interaction of Nestin

Advanced Science, Volume 13, Issue 43, 3 August 2026.
IGF2BP1‐mediated m6A stabilization sustains SMC1A expression, enabling cohesin‐associated chromatin regulation of Nestin in hepatocellular carcinoma. This work reveals an epitranscriptomic‐chromatin‐cytoskeletal regulatory axis linked to malignant phenotypes and identifies SMC1A as a biologically relevant vulnerability in HCC.

Cohesin mutations in human cancer [PDF]

Biochimica et Biophysica Acta (BBA) - Reviews on Cancer, 2016
Cohesin is a highly-conserved protein complex that plays important roles in sister chromatid cohesion, chromatin structure, gene expression, and DNA repair. In humans, cohesin is a ubiquitously expressed, multi-subunit protein complex composed of core subunits SMC1A, SMC3, RAD21, STAG1/2 and regulatory subunits WAPL, PDS5A/B, CDCA5, NIPBL, and MAU2 ...

Genomic Contributors to Congenital Diaphragmatic Hernia: Results of Exome Sequencing in 560 Probands and Cross Reference of Findings in an Independent Cohort

American Journal of Medical Genetics Part A, Volume 200, Issue 8, Page 1821-1831, August 2026.
ABSTRACT There is a strong genetic contribution to the etiology of congenital diaphragmatic hernia (CDH). This study evaluated genetic testing results and diagnostic yield for fetuses and children with CDH. This was a retrospective cohort study of exome sequencing (ES) performed at GeneDx for fetuses and children ≤ 18 years of age with CDH compared ...

Evolution of N‐terminal mechanical lability as a determinant for Type III secretion

Protein Science, Volume 35, Issue 8, August 2026.
Abstract Many Gram‐negative pathogens critically depend on the Type III secretion system (T3SS) to inject effector proteins into host cells for colonization. Because the channel of the T3SS is narrow (~2 nm), effectors must be unfolded for secretion.

The ATPases of cohesin interface with regulators to modulate cohesin-mediated DNA tethering

eLife, 2015
Cohesin tethers together regions of DNA, thereby mediating higher order chromatin organization that is critical for sister chromatid cohesion, DNA repair and transcriptional regulation. Cohesin contains a heterodimeric ATP-binding Cassette (ABC) ATPase comprised of Smc1 and Smc3 ATPase active sites.

Sister centromere fusion during meiosis I depends on maintaining cohesins and destabilizing microtubule attachments.

PLoS Genetics, 2019
Sister centromere fusion is a process unique to meiosis that promotes co-orientation of the sister kinetochores, ensuring they attach to microtubules from the same pole during metaphase I.

Dissecting Pirtobrutinib Resistance in Mantle Cell Lymphoma Through Single‐Cell Multi‐Omics

American Journal of Hematology, Volume 101, Issue 7, Page 1632-1649, July 2026.
ABSTRACT Pirtobrutinib (PBN), a non‐covalent BTK inhibitor, has been approved by the FDA for relapsed/refractory mantle cell lymphoma (MCL); however, resistance to PBN has been observed. To dissect the molecular dynamics driving PBN resistance, we performed integrative single‐cell multi‐omic profiling (scRNA‐seq, scATAC‐seq, and scDNA‐seq) on ...

Quantitative Control of Transposable Elements: From Genome Plasticity to Immune Regulatory Circuits

Cell Biochemistry and Function, Volume 44, Issue 7, July 2026.
ABSTRACT Transposable elements (TEs) constitute nearly half of the human genome and are increasingly recognized as context‐dependent regulators of genome function rather than passive repetitive DNA. This Review synthesizes classical and recent evidence on TE biology, including TE classification, mechanisms of mobilization, host restriction pathways ...
