Researchers at Baylor College of Medicine have developed a novel method to profile different types of DNA methylation, including 6mA, 4mC and 5mC. The NT-seq method allows for efficient and cost-effective detection of these epigenetic markers in various organisms, paving the way for further studies on cancer epigenetics.
A new study explains how leukemia cells can transform into harmless immune cells through epigenetic changes, potentially leading to novel therapies for blood malignancies. The METTL3 gene is identified as a key controller of this process.
A new study at Lund University found distinct epigenetic differences between subgroups of patients with type 2 diabetes, associated with different risks of developing common complications. Epigenetic biomarkers can be used to predict complications and tailor treatments for individual patients.
Researchers have identified the Xist gene as a critical regulator of fetal development in mice, leading to miscarriage and abnormal placentas when epigenetic instructions are missing. The study's findings suggest that failed Xist imprinting can be 'cured' by targeting specific genes involved in histone modifications.
A team of researchers has discovered a novel epigenetic mark in bdelloid rotifers, small freshwater animals, that allows them to control jumping transposons. This marks the first time a horizontally transferred gene has reshaped the gene regulatory system in a eukaryote.
A new study found that pollutants can be transmitted over many generations in water fleas, persisting long enough to influence the evolutionary process. The effects of low doses of pollutants were detected even after switching to clean water, indicating stable epigenetic marks passed down through generations.
The Sanford Children's Genomic Medicine Consortium has initiated a whole genome sequencing research project to investigate undiagnosed illnesses in children with suspected inborn errors of immunity. The study aims to sequence the genomes of up to 25 patient genomes and learn information that can benefit patients and others.
Scientists have identified specific epigenetic signatures for nociceptive and neuropathic pain, allowing for quicker and more reliable classification. This breakthrough enables a simple blood test to determine the type of pain an individual suffers from, paving the way for targeted treatment.
Researchers found that toxin-adapted fish passed on epigenetic mutations to their freshwater offspring, with an 80% overlap in DNA methylation regions. This study provides evidence for the long-term effects of toxic exposure on epigenetics, with implications for understanding human health and environmental adaptations.
Researchers discover how cancer cells reorganize DNA in 3D structure to ramp up activity of cancer-promoting genes. Epigenetic marks alter chromosome structures, leading to novel local interactions and over-expression of oncogenes.
A team of scientists discovered how epigenetics helps place egg cells in stasis by adding distinctive patterns of marks to their DNA. The MLL2 protein plays a key role in this process, and its absence can cause disease.
Researchers have identified key epigenetic marks and proteins that control the production of antibodies in the immune system. By understanding these systems, scientists hope to develop new diagnostic tests and therapies to boost the body's response to infection.
Researchers at the University of Helsinki identified a genetic variation associated with damage caused by maternal alcohol consumption. The study found that this variation affects epigenetic marks on placentas and newborn head size, depending on inherited genetic factors.
Researchers at Max Planck Institute of Immunobiology and Epigenetics found that epigenetic marks passed from mother to embryo are essential for embryogenesis. These marks, such as H3K27me3, regulate gene expression and can be inherited through generations.
Researchers discovered YEATS domain proteins as the first reader of histone lysine crotonylation, a critical epigenetic mark. This discovery has implications for human disease, particularly in cancers such as leukemia and glioblastoma.
Researchers at the University of Southampton discovered specific DNA markers linked to seasonal births and allergic disease. Epigenetic marks present at birth were found to influence gene expression for up to 18 years later.
A recent study published in Cell Metabolism found that a man's weight affects the heritable information contained in sperm. The study compared lean and obese men and found differences in epigenetic marks associated with appetite control. Further research is needed to understand the implications of these findings on offspring.
A new study has successfully detected epigenetic marks in 29 out of 30 ancient human remains from five North American archaeological sites, spanning over 4,500 years. The findings could provide insights into how past environments affected the physical traits and health of ancient populations.
Researchers have obtained the first precise estimates of how often epigenetic marks appear or disappear in the plant Arabidopsis thaliana. The study found that epigenetic mutations are about 100,000 times more likely than DNA sequence mutations and nearly all are neutral, not affecting gene expression.
Scientists discovered that epigenetic marks in plants can affect complex traits such as flowering time and plant architecture. These marks are stably passed on to later generations, opening up new possibilities for plant breeding and evolution.
Research reveals mechanism of epigenetic reprogramming and how it may affect gene expression, potentially leading to disease susceptibility in offspring. The study found that some methylation marks can escape reprogramming and be passed on to offspring.
A new study by A*STAR scientists reveals that the protein TRIM28 plays a crucial role in preserving epigenetic marks during nuclear reprogramming, ensuring proper development of the embryo. The absence of TRIM28 leads to severe developmental defects and multiple pregnancy failures.
Researchers will explore epigenetic changes and their relationship with memory formation, cognitive decline, and Alzheimer's disease. The studies aim to understand how life experiences contribute to the biological changes of Alzheimer's and may lead to therapeutic interventions.
A team of Johns Hopkins experts suggests that epigenetic changes occurring over a person's lifetime may explain why disease susceptibility increases with age. They found that methylation levels changed in almost one-third of individuals over an 11-year span, and family members tended to exhibit similar changes.
A study by McGill University scientists found that child abuse may cause differences in epigenetic marking on genes in the brains of men who killed themselves. The researchers also discovered that simple maternal behavior during early childhood has a profound effect on genes and behavior, which can be reversed through treatments.
Researchers propose a new approach to understanding epigenetics in common diseases, such as cancer, diabetes, and heart disease. The framework aims to analyze epigenetic marks across the entire genome, revealing their role in disease variability and progression.
