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.

Researchers identify a new risk factor for multiple neurodegenerative diseases

Scientists at the HudsonAlpha Institute for Biotechnology, the University of California, San Francisco (UCSF), and the University of Alabama at Birmingham (UAB), have identified a new risk factor for multiple neurodegenerative diseases.

Age-related DNA modifications linked with susceptibility to eye disease

National Eye Institute researchers profiling epigenomic changes in light-sensing mouse photoreceptors have a clearer picture of how age-related eye diseases may be linked to age-related changes in the regulation of gene expression.

NEI researchers link age-related DNA modifications to susceptibility to eye disease

Researchers profiling epigenomic changes in mouse photoreceptors suggest that age-related eye diseases may be linked to gene expression.

Women born by cesarean have greater risk of obesity and diabetes

A new study published in the open-access journal JAMA Network Open in April 2020 suggests that women born by way of a Cesarean section are at higher risk of developing obesity as well as type 2 diabetes mellitus in adult life.

Researchers elucidate new mechanism for controlling DNA methylation in cells

Why normal cells turn into cancer cells One of the factors is deeply related to the failure of the cell differentiation mechanism called DNA methylation.

Characterization of DNAm status of MMPs and TIMPs in atheromatous plaques

Oncotarget Volume 11, Issue 10 reported that the statistically associated Cp G sites were analyzed in blood samples from two separate atherothrombotic stroke cohorts, ischemic stroke-cohort 1: 37 atherothrombotic patients and 6 controls, ischemic stroke-cohort 2: 80 atherothrombotic patients and 184 controls.

Length of pregnancy related to chemical DNA changes in newborns

Researchers from Karolinska Institutet in Sweden have together with an international team mapped the relationship between length of pregnancy and chemical DNA changes in more than 6,000 newborn babies.

Potential genetic test for earlier Alzheimer's diagnosis

A new study published in the journal Epigenetics in February 2020 reports that changes in the methylation status of the Presenilin 1 (PSEN1) gene could help diagnose Alzheimer's disease (AD) earlier. This study shows for the first time that methylation of this gene is a common feature in AD.

New way to chart human genome with CRISPR/nanopore sequencing technique

In search of new ways to sequence human genomes and read critical alterations in DNA, researchers at Johns Hopkins Medicine say they have successfully used the gene cutting tool CRISPR to make cuts in DNA around lengthy tumor genes, which can be used to collect sequence information.

Biological age metric can provide new opportunities for preventative healthcare

People age in different ways. Biological age is a metric that scientists use to predict health risks, the relevance of which can be enhanced by combining different markers. Particularly important markers are frailty and the epigenetic clock, write researchers from Karolinska Institutet in a study published in eLife.

Higher maternal blood pressure linked to placental gene modifications

Higher maternal blood pressure in pregnancy is associated with chemical modifications to placental genes, according to a study by researchers from the Eunice Kennedy Shriver National Institute of Child Health and Human Development, part of the National Institutes of Health.

UMass Amherst study aims to develop new test for BRCA-positive lactating moms

Breastfeeding women with a pathogenic BRCA1 or BRCA2 genetic mutation face a significant risk, even at a young age, of breast and ovarian cancer.

3D structure of DNA is 'rewired' in hormone-resistant ER+ breast cancers

Epigenetic changes occur in the DNA of breast cancer cells that have developed a resistance to hormone therapy, an effective treatment for ER+ breast cancer, which accounts for 70% of all diagnoses.

'Methylation clock' gene found to have functional role in aging of the eye

A lengthy-named gene called Elongation of Very Long Chain Fatty Acids Protein 2 or ELOVL2 is an established biomarker of age.

Scientists identify molecules capable of inhibiting DNA methylation, effectively killing malaria parasites

Parasites in the genus Plasmodium, which cause malaria, are transmitted to humans through bites from infected mosquitoes.

Edematous severe acute malnutrition linked to DNA modification

A group led by researchers at Baylor College of Medicine has identified significant differences at the epigenetic level - the chemical tags in DNA that help regulate gene expression - between two clinically distinct forms of acute childhood malnutrition known as edematous severe acute malnutrition (ESAM) and non-edematous SAM (NESAM).

CSIRO researchers find simple way to estimate lifespan of animals

Researchers at CSIRO, Australia’s national science agency, have discovered a simple way to estimate how long a species lives.

Research suggests new strategies for developing psoriasis therapies

Psoriasis is a skin disorder that affects at least 100 million individuals worldwide. Its economic impact is more than $10 billion annually in the U.S. alone.

Epigenomic techniques used to fight disease

Humans differ from one another in many ways, including how they react to disease, because of their DNA blueprint, as well as the difference in the environments they face. These factors combine to make each person unique. Now a new study published in the journal Nature Protocols reports the development of a promising technology to uncover the process by which the body fights diseases in different ways.

Baylor researchers report creation of an 'epigenetic couch potato' mouse

Why is it that some people love to exercise, and others hate it? Most people would assume it's all due to genetics, but a new Baylor College of Medicine led study in mice shows for the first time that a different molecular level of regulation - epigenetics - plays a key role in determining one's innate drive to exercise.
