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.

Cancer-related DNA changes may appear in blood years before diagnosis

Researchers found that genome-wide plasma cfDNA methylation profiles collected before diagnosis contained early molecular signatures associated with future prostate and breast cancer, with prostate silencer methylation providing the stronger risk stratification. Breast enhancer signals were weaker and varied by subtype and disease stage, indicating that cfDNA methylation may have greater value for risk assessment and surveillance than as a standalone diagnostic test.

High adolescent BMI linked to faster biological aging in adulthood

A study by the Faculty of Sport and Health Sciences at the University of Jyväskylä, Finland, found that a high adolescent body mass index (BMI) may be linked to accelerated biological aging in adulthood.

Study: Multiple dietary patterns linked to slower biological aging

A study by DZNE finds that healthy eating is associated with slower biological aging-and that there is more than one way to eat healthily.

New integrated framework advances precision surgery for liver cancer

Hepatocellular carcinoma is the sixth most common malignancy and the third leading cause of cancer-related death globally.

Cognitive behavioral therapy for insomnia may slow biological aging in older adults

A new UCLA Health study found that treatment of insomnia using cognitive behavioral therapy slowed the pace of biological aging in older adults.

Researchers found one childhood behavior linked to folic acid use before pregnancy

Researchers analyzed 646 children aged 2–8 years and their 563 mothers to examine whether maternal folic acid supplementation before conception was associated with childhood behavioral difficulties. Preconception supplementation was associated with a 34% lower risk of peer relationship problems, while no significant associations were found for total behavioral difficulties, emotional, conduct, hyperactivity/inattention, or prosocial problems.

Research improves understanding of biological mechanisms behind cluster headaches

Inflammation, altered gene regulation, and exposure to substances in tobacco smoke may all contribute to the development of cluster headache.

Stress gene switches on more easily in the brains of people with schizophrenia

Experts at the University of Sydney have found that a gene involved in regulating the body's response to stress switches on more easily in the brains of people who live with schizophrenia.

Maternal obesity alters fetal liver metabolism via placental molecular signals

A mother's obesity during pregnancy may send molecular signals across the placenta that permanently alter her son's liver metabolism, according to a new study in mice published in Nature Communications.

Nicoya is a famous blue zone. DNA aging estimates tell a more complicated story

Researchers developed a SuperLearner framework that combines established epigenetic clocks with machine learning to compare DNA methylation-based aging in residents of Costa Rica’s Nicoya Blue Zone with other Costa Ricans. Initial calibration suggested a modest younger epigenetic age among Nicoyans, but accounting more closely for age distribution substantially reduced the apparent advantage, highlighting the importance of population-specific calibration in longevity research.

New machine learning tool identifies hidden epigenetic disease patterns

In a study recently published in Nature Communications, researchers from Berlin, Potsdam, and Jena present a new method for analyzing the epigenome, the genome's control system that determines which genes are switched on and off.

Scientists compared 51 longevity studies to see which aging biomarkers respond most reliably

Researchers analyzing 51 longitudinal intervention studies found that reliable generation 2+ DNA methylation biomarkers, particularly those predicting mortality or pace of aging, were the most responsive to interventions aimed at longevity or healthspan. Pharmacological and lifestyle interventions produced the strongest biomarker changes, but the authors cautioned that responsiveness does not yet establish these measures as validated surrogate endpoints for slower aging or longer life.

Deep-learning tissue clocks reveal how organs age and leave disease-linked signals in blood

Deep learning applied to more than 25,000 histopathology slides revealed tissue-specific structural signatures of biological aging that tracked telomere attrition, pathology, comorbidity, and molecular changes more closely than chronological age alone.

AI-based "tissue clocks" measure the biological age of human organs

AI-based "tissue clocks" can estimate the biological age of human organs from histological images, researchers at the CeMM Research Center for Molecular Medicine of the Austrian Academy of Sciences and the Ludwig Boltzmann Institute for Network Medicine (LBI-NetMed) at the University of Vienna showed.

Opening the black box of biological aging clocks

What do "epigenetic clocks" actually measure? These lab tests have become popular tools for studying biological aging, or how the body's cellular function changes at a faster or slower rate than expected.

Your social life may leave a mark on how fast you age

Positive social experiences were associated with longer survival, while childhood adversity predicted shorter survival in a 1,309-person longitudinal cohort followed for nearly 15 years. Epigenetic aging, particularly GrimAge2, emerged as the strongest potential pathway linking social experiences with mortality risk.

Exhausted T cells balance graft tolerance and infection risk

A comprehensive new review examines the complex role of T cell exhaustion in organ transplantation, highlighting how this dysfunctional immune state can both promote graft tolerance and create vulnerabilities to infection and malignancy.

PIWI proteins and piRNAs may unlock more effective stem cell therapies

Scientists are shedding new light on a little-known biological system that could help unlock the full potential of stem cell therapy, one of the most promising areas of modern medicine.

Five epigenetic clocks reveal shared and distinct signals of aging

Researchers linked five epigenetic clocks to distinct blood gene-expression patterns and biological pathways in 3,227 Health and Retirement Study participants. TAGS derived from these patterns often showed stronger associations with frailty, functional measures, morbidity, and mortality than their parent clocks, although further validation is needed.

New therapy targets Hippo pathway to fight treatment-resistant acute myeloid leukemia

Researchers at The University of Texas MD Anderson Cancer Center have discovered that an investigational epigenetic therapy remained effective in treatment-resistant acute myeloid leukemia (AML) through activating the Hippo pathway, a tumor-suppressing pathway linked to cancer growth and drug resistance.
