Researchers at the Wyss Institute have identified vorinostat as a promising treatment for Rett Syndrome using an AI-driven drug discovery process and innovative disease modeling. The findings demonstrate disease-modifying abilities across multiple tissues, offering hope for a potentially curative treatment.
Researchers found that maternal iron deficiency can lead to male-to-female sex reversal in mouse embryos due to impaired Sry gene activation. Iron is necessary for KDM3A's enzymatic activity, which removes histone methylation allowing the Sry gene to become active.
UCSF researchers identify a molecular timer controlling mouse birth timing, which could lead to new tests for human preterm labor risk and interventions. DNA packaging during pregnancy plays a crucial role in regulating gene expression, with KDM6B working as a 'timer' that winds down over time.
A recent study by Nara Institute of Science and Technology reveals a new mechanism for dynamic gene silencing and reactivation, highlighting the intricate roles of proteins like SDG7. The research team identified a competitive interaction between SDGs and PRC2 at PREs, allowing for efficient gene activation through H3K36 methylation.
Researchers discovered that H3K9 methylation is not a simple 'off switch' but rather a 'dimmer switch' that fine-tunes DNA transcription in thale cresses. The study found that two other proteins, LDL2 and ASHH3, play a crucial role in this process.
Researchers have identified a new method to distinguish histidine methylation in histone proteins, revealing its role in regulating genomic DNA folding. The study found histidine methylation at specific residues in histones H2A and H3, primarily affecting lysine residues.
A study reveals a unique epigenetic biotimer mechanism controlling floral meristem termination and stamen development in Arabidopsis thaliana. The team discovered that AGAMOUS serves as a master conductor orchestrating gene expression through cell cycle-coupled H3K27me3 dilution.
Researchers from Swansea University and Université Grenoble Alpes demonstrate the effectiveness of selenium nanoparticles in killing ovarian cancer cell models. The study reveals a novel biological mechanism underlying the anti-cancer effect, involving histone methylatransferases and epigenetic processes.
The study reveals that SETD1A overexpression is associated with poorer disease-free survival in pancreatic cancer patients. Artificially cultured cells showed increased cell growth and migration when SETD1A levels were overexpressed, while knocking down SETD1A expression led to decreased RUVBL1 gene expression.
Researchers at the University of Illinois Chicago found that gene editing can reverse epigenetic changes in the brain caused by adolescent binge drinking, leading to a decrease in anxiety and excessive drinking behavior. The study used CRISPR-dCas9 technology to manipulate histone acetylation and methylation processes at the Arc gene.
Researchers in Brian Strahl's lab reveal that different chemical modifications of a single amino acid residue on histones can have unique and shared functions in gene expression and DNA repair. They found that specific methylation states on histones regulate diverse chromatin functions, including responding to stress conditions.
A recent study published in Science Advances found that physical forces alone can activate genes in human cells, leading to increased gene expression. The researchers discovered that histone proteins play a key role in determining which genes are responsive to stretching forces.
A study reveals putative epigenetic signatures of chronic undernutrition tied to growth stunting in humans. Chronic undernutrition can result in persistent effects throughout adulthood, with changes in histone methylation patterns found in peripheral blood mononuclear cells from undernourished children.
Researchers at UC Santa Cruz found that both sperm and eggs transmit a memory of gene repression to embryos, which is then transmitted through multiple cell divisions. This epigenetic memory plays a crucial role in regulating gene expression and development.
Researchers at Stowers Institute for Medical Research confirm the molecular mechanics of a key regulatory complex implicated in human leukemia are conserved from yeast to humans. They also identify the common molecular shape at the center of the complex, which regulates gene expression through histone methylation.
The Stowers Institute's Workman Lab has made a groundbreaking discovery of a novel histone demethylase protein complex, which plays a crucial role in regulating transcription elongation. The research reveals that this protein complex associates with the heterochromatin protein 1a and stimulates its histone demethylation activity.
The Stowers Institute's Shilatifard Lab has published findings on the molecular machinery required for translating histone crosstalk between H2B monoubiquitination and H3 methylation. This process is highly conserved from yeast to humans and plays a crucial role in gene expression.
DNMT1 and G9a interact to positively influence each other's catalytic activities and maintain epigenetic marks. The interaction impairs histone H3K9 methylation when DNMT1 is knocked down.
Researchers have linked Polycomb gene silencing to histone protein methylation, explaining the permanence of Hox gene silencing. The study found that Polycomb proteins function through methylating a specific lysine residue on histone 3, leading to permanent gene silencing.
Researchers have identified G9a as a chromatin-modifying enzyme essential for normal development. Studies show that G9a deficiency leads to severe developmental growth retardation and increased programmed cell death, highlighting the enzyme's critical role in regulating gene expression during embryogenesis.
Researchers have identified a critical protein, SET7, that regulates gene expression by modifying histone H3. This discovery may lead to new treatments for diseases and provide insights into using stem cells to generate organs. The study reveals that SET7 makes chromatin structure more open, allowing other proteins to access genes.
