DNA Methylation News and Research

RSS

DNA methylation is a type of chemical modification of DNA that can be inherited and subsequently removed without changing the original DNA sequence. As such, it is part of the epigenetic code and is also the most well characterized epigenetic mechanism.

New study explains how brain tumors evolve to resist treatment

A form of glioma, a type of brain cancer, tends to progress towards greater malignancy due to an increasing tendency of the glioma cells to transform into immature, stem-cell-like states, according to a study led by investigators at Weill Cornell Medicine, the New York Genome Center, Harvard Medical School and Mass General Brigham.

Study uncovers genetic clues behind sex differences in Parkinson's disease

New research presented today (Wednesday) at the Federation of European Neuroscience Societies (FENS) Forum 2026 has discovered some of the genetic changes in brain cells that may help to explain why more men than women develop Parkinson's disease.

Air pollution may impact genes involved in sperm development

New research presented today at the 42nd Annual Meeting of the European Society of Human Reproduction and Embryology (ESHRE) suggests that exposure to air pollution may impact genes associated with sperm development, raising new questions about male fertility, pregnancy outcomes and offspring health.

Study links DNA methylation to aggressive prostate cancer behavior

The prostate is the single organ most frequently afflicted by cancer in men. Prostate cancer affects approximately 4 million American men, with another 330,000 men expected to be diagnosed with the condition this year alone.

Vitamins A and D may support healthier lungs in asthma patients

Higher levels of circulating vitamin A are linked to better lung function in children and adults with asthma, while vitamin D shows similar benefits in adults, including slower biological ageing, finds the first study of its kind, published online in the respiratory journal Thorax.

Rare genetic condition offers new insights into human aging process

Scientists have discovered a rare genetic condition which causes people to age at a much faster rate, offering fresh insights into the aging process.

Psychological traits may uncover why Alzheimer’s biology differs between patients

In 822 deceased older adults from ROS and MAP, researchers linked stable psychological traits to multi-omic molecular subtypes of Alzheimer’s dementia using postmortem brain tissue from the dorsolateral prefrontal cortex. Neuroticism and loneliness were associated with molecular progression, while purpose in life showed subtype-specific inverse associations, suggesting psychological traits may align with Alzheimer’s biology beyond conventional neuropathology.

Researchers advocate local data strategies for early cancer detection

Researchers are calling for the application of locally driven strategies, supported by stronger regional evidence, to improve early cancer detection and precise care.

Childhood stress leaves lasting epigenetic marks across the body

The experiences we face early in life may leave their marks on our health in ways that echo across decades-and even across the entire body.

New biological age tools could reveal health risks before symptoms appear

A JCI review traces biological age measurement from functional tests and blood biomarkers to epigenetic, proteomic, imaging, wearable, and AI-based clocks. It finds that these tools can improve risk prediction beyond chronological age, but standardization, interpretability, and prospective validation are needed before routine clinical use.

Semaglutide, omega-3s and diet shift epigenetic aging clocks in human studies

A systematic review identified 41 human studies evaluating interventions targeting next-generation DNA methylation-based aging clocks. Pharmaceutical, lifestyle, supplement, clinical, and psychosocial interventions shifted some clock outputs, but these biomarkers remain investigational rather than proven clinical surrogates.

New AI system classifies brain tumors with unprecedented accuracy

Experts in Heidelberg have developed an AI system that can classify brain tumors with unprecedented accuracy using standard microscopic tissue sections.

AI predicts meningioma recurrence from routine pathology slides

Mayo Clinic researchers and collaborators have shown that artificial intelligence (AI) can analyze routine pathology slides to help classify meningiomas, the most common primary brain tumor in adults, and predict a patient's risk of tumor recurrence.

GLP-1 therapy linked to slower biological aging processes

Glucagon-like peptide-1 (GLP-1) receptor agonist medications have gained widespread attention for effectively treating obesity, lowering blood sugar and decreasing the risk of cardiovascular disease.

DNA methylation variability may improve precision cancer treatment strategies

A new review article brings attention to the critical role of DNA methylation heterogeneity in shaping the tumor microenvironment, highlighting its growing importance in understanding cancer progression and advancing more precise treatment strategies.

Epigenetic research links genetics and environment to mental disorders

Mental disorders, such as obsessive-compulsive disorder (OCD) and bipolar disorder, can strongly affect daily life.

Regular arts and physical activity linked to slower aging

Research shows that leisure activities, including arts engagement and physical exercise, are linked to slower epigenetic aging and improved health outcomes.

Regular arts engagement may help slow biological aging process

Regularly taking part in arts activities such as reading, listening to music or visiting a gallery or museum may slow the pace of biological aging, suggests a new study by University College London (UCL) researchers.

Study reveals epigenetic adaptation of beta cells across lifespan and disease

As people age, most maintain normal blood sugar even as insulin resistance tends to rise. New research suggests that pancreatic beta cells help meet this demand through gradual epigenetic changes in regulatory regions of the genome that support beta-cell identity and function.

GADD45B promotes apoptosis in intestinal injury through DNA demethylation

Intestinal ischemia/reperfusion (I/R) injury is a common pathophysiological phenomenon that is widely present in various primary intestinal diseases and systemic critical illnesses, potentially leading to multiple organ dysfunction and failure, with high morbidity and mortality.
