Deletion of a Pax1 Sex‐Associated Genomic Region Associated With Adolescent Idiopathic Scoliosis Leads to Disc Degeneration, Instability, and Vertebral Rotation in Mice

JOR SPINE, Volume 9, Issue 2, June 2026.
Overview of the effects of Pax1‐SAR deletion on gene expression, IVD degeneration, and resultant scoliotic‐like curvature between sexes. Proposed mechanism of sex‐dependent changes in gene expression in females (right) and males (left), resulting in sex‐dependent disc degeneration and scoliotic phenotypes.

Expression of the CTCF gene in bovine oocytes and preimplantation embryos

Genetics and Molecular Biology, 2007
The CCCTC - binding factor (CTCF) is a protein involved in repression, activation, hormone-inducible gene silencing, functional reading of imprinted genes and X-chromosome inactivation. We analyzed CTCF gene expression in bovine peripheral blood, oocytes

Multi‐Omics Reveals Early Pregnancy Placental Dysfunction Associated With Preterm and Term Preeclampsia

MedComm, Volume 7, Issue 6, June 2026.
Preeclampsia, a severe pregnancy‐induced disorder unique to humans, affects ∼5% of pregnancies globally. To understand the pathogenesis of preeclampsia, this study performed a comprehensive multi‐omics analysis of early pregnancy placental biopsies (chorionic villus samples) from pregnancies that later developed preterm/term preeclampsia, compared to ...

Comprehensive identification and annotation of cell type-specific and ubiquitous CTCF-binding sites in the human genome. [PDF]

PLoS ONE, 2012
Chromatin insulators are DNA elements that regulate the level of gene expression either by preventing gene silencing through the maintenance of heterochromatin boundaries or by preventing gene activation by blocking interactions between enhancers and ...

Oxidative Stress and DNA Epigenetic Modifications in Cancer: Mechanisms and Targeted Therapeutics

MedComm – Oncology, Volume 5, Issue 2, June 2026.
Reactive oxygen species (ROS) modulate DNA methyltransferases (DNMTs), ten‐eleven translocation family proteins (TETs) and their cofactors, reshaping 5‐methylcytosine (5mC)/5‐hydroxymethylcytosine (5hmC)/5‐formylcytosine (5fC) landscapes and gene expression in cancer cells. In turn, epigenetic control of antioxidant and metabolic pathways feeds back on

Direct identification of insulator components by insertional chromatin immunoprecipitation. [PDF]

PLoS ONE, 2011
Comprehensive understanding of mechanisms of epigenetic regulation requires identification of molecules bound to genomic regions of interest in vivo. However, non-biased methods to identify molecules bound to specific genomic loci in vivo are limited ...

Dysregulation of the PATZ1/CTCF Balance Silences ZBTB20 to Drive Melanoma Progression

Advanced Science, Volume 13, Issue 26, 8 May 2026.
This study uncovers a new oncogenic mechanism in melanoma. The transcription factor PATZ1 competes with the architectural protein CTCF for DNA binding, thereby disrupting a specific chromatin loop and silencing the tumor suppressor ZBTB20. This event unleashes the pro‐tumorigenic PMEPA1‐p38‐STAT1 signaling axis, promoting cancer progression.

Cis‐regulatory and long noncoding RNA alterations in breast cancer – current insights, biomarker utility, and the critical need for functional validation

Molecular Oncology, Volume 20, Issue 4, Page 877-893, April 2026.
The noncoding region of the genome plays a key role in regulating gene expression, and mutations within these regions are capable of altering it. Researchers have identified multiple functional noncoding mutations associated with increased cancer risk in the genome of breast cancer patients.
