Chromium disrupts chromatin organization and CTCF access to its cognate sites in promoters of differentially expressed genes

Epigenetics, 2018
Hexavalent chromium compounds are well-established respiratory carcinogens used in industrial processes. While inhalation exposure constitutes an occupational risk affecting mostly chromium workers, environmental exposure from drinking water is a ...

Mutation type‐specific transcriptomic signatures and readthrough therapy rescue in SMC1A‐related developmental and epileptic encephalopathy

Epilepsia, EarlyView.
Abstract Objective This study was undertaken to investigate the molecular consequences of pathogenic variants in the SMC1A gene—particularly those associated with developmental and epileptic encephalopathy (DEE85)—and to evaluate the therapeutic potential of ataluren in restoring SMC1A function and mitigating disease‐related transcriptomic and genomic ...

A Novel Mechanism for CTCF in the Epigenetic Regulation of Bax in Breast Cancer Cells

Neoplasia: An International Journal for Oncology Research, 2013
We previously reported the association of elevated levels of the multifunctional transcription factor, CCCTC binding factor (CTCF), in breast cancer cells with the specific anti-apoptotic function of CTCF.

Inverse association between obesity and intestinal endometriosis: Findings from a cross‐sectional study

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective This study evaluates the association between obesity and the presence of bowel endometriosis in patients undergoing surgery. Methods A retrospective cross‐sectional observational study was conducted with patients treated between September 2023 and December 2024, at a specialized endometriosis outpatient clinic of a tertiary hospital ...

CTCF physically links cohesin to chromatin [PDF]

Proceedings of the National Academy of Sciences, 2008
Cohesin is required to prevent premature dissociation of sister chromatids after DNA replication. Although its role in chromatid cohesion is well established, the functional significance of cohesin's association with interphase chromatin is not clear.

Optical mapping reveals a higher level of large‐scale structural variants in a family with paternally transmitted myotonic dystrophy and independent Parkinson's disease

The Journal of Pathology, EarlyView.
Abstract Myotonic dystrophy type 1 (DM1) is a clinically challenging multisystem neuromuscular hereditary disorder, with generational increase in severity and earlier age at onset. It is caused by an unstable cytosine‐thymine‐guanine repeat expansion at the DMPK locus, accompanied by associated genetic and epigenetic modifications.

CTCF, Cohesin, and Chromatin in Human Cancer [PDF]

Genomics & Informatics, 2017
It is becoming increasingly clear that eukaryotic genomes are subjected to higher-order chromatin organization by the CCCTC-binding factor/cohesin complex. Their dynamic interactions in three dimensions within the nucleus regulate gene transcription by changing the chromatin architecture.

Exploring Interactive Effects of Arsenic and Selenium Exposure on Larval Zebrafish (Danio rerio)

Environmental Toxicology, EarlyView.
ABSTRACT Arsenic contamination in aquatic ecosystems is a major environmental concern. Selenium (Se) helps mitigate oxidative stress and hence could reduce the toxic effects of arsenic. However, Se can also be toxic at high concentrations. Given that these metalloids commonly co‐occur in the environment, there is a pressing need for further research ...

CTCF fences make good neighbours [PDF]

Nature Cell Biology, 2017
CCCTC-binding factor (CTCF) sites are enriched at the boundaries of topologically associated domains (TADs), but their function within TADs is unclear. Removal of sub-TAD CTCF sites adjacent to the α-globin enhancers is now shown to result in inappropriate activation of neighbouring genes.

The Functional Role and Molecular Characterization of the Therapeutic Target CLDN6 in Germ Cell Tumors

Andrology, EarlyView.
ABSTRACT Background The tight junction protein CLDN6 has been identified as a cancer‐associated cell surface marker that is rarely expressed in healthy tissues. In testicular germ cell tumors (GCT), CLDN6 is particularly detectable in seminomas, embryonal carcinomas, and choriocarcinomas.
