'Primitive' stem cells shown to replace and repair damaged blood vessels in the retina

Johns Hopkins Medicine scientists say they have successfully turned back the biological hands of time, coaxing adult human cells in the laboratory to revert to a primitive state, and unlocking their potential to replace and repair damage to blood vessels in the retina caused by diabetes.

Biomarker in saliva linked to emergence of childhood obesity

A molecular marker in saliva is associated with the emergence of childhood obesity in a group of preschool-aged Hispanic children.

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.

Coriell researchers find new genetic indicator of obesity risk

Obesity is among the most common complex diseases in the United States and has been a stubborn public health challenge for decades. Its causes are wide ranging, but genetic heritability is increasingly understood to be an influential factor in determining a person's risk for the disease.

Vapers exhibit similar chemical changes in their genome as smokers

Biologically important changes in DNA seen in smokers are also being found in people who vape, according to a new study published in the journal Epigenetics.

DNA misfolding linked to heightened risk for Type 1 diabetes

It's known that genetics, or an inherited genome, is a major determinant of one's risk for autoimmune diseases, like Type 1 diabetes. In human cells, a person's genome--about six feet of DNA--is compressed into the micrometer space of the nucleus via a three-dimensional folding process.

Researchers simulate leaky gut conditions using 3D models of human intestines

Once a vague scapegoat for a variety of ills, increasing evidence suggests a condition known as "leaky gut" -- in which microbes and other molecules seep out of the intestines -- may be more common, and more harmful, than previously thought.

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.

Researchers take first step to find causes of sarcopenia

Researchers have gained new insight into the mechanisms involved in how skeletal muscles lose their mass and strength as people age, called sarcopenia.

Penn researchers track defective sperm epigenome linked to male infertility

One out of eight couples has trouble conceiving, with nearly a quarter of those cases caused by unexplained male infertility. For the past decade, research has linked that infertility to defective sperm that fail to "evict" proteins called histones from DNA during development.

Important discovery about male infertility could lead to new treatments

Using a new mouse model, Penn Medicine researchers have identified defects in the sperm epigenome that cause male infertility.

Coriell scientist awarded grant to explore epigenetic drivers of breast cancer

Shoghag Panjarian, PhD, a research scientist at the Coriell Institute for Medical Research, has been awarded a grant from the W. W. Smith Charitable Trust to support her search for epigenetic factors that contribute to the development and growth of breast cancer.

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.

Fertility treatments cause epigenetic changes in mouse embryos, study finds

Though epigenetic disorders - diseases caused by faulty gene expression - are still rare overall, babies born using fertility treatments have up to an 11-fold higher risk of inheriting them.

Discovery in C. difficile biology opens new window to developing treatments for dangerous infections

A process called sporulation that helps the dangerous bacterium Clostridium difficile (C. difficile) to survive inhospitable conditions and spread is regulated by epigenetics, factors that affect gene expression beyond the DNA genetic code, researchers at the Icahn School of Medicine at Mount Sinai report.

25 Nov 2019

Recent discovery about C. difficile could pave the way for new treatments

Researchers have found that sporulation, which helps the bacterium C. difficile survive and spread, is regulated by epigenetics.

Study shows how drinking patterns reprogram circadian metabolism in the liver

Drinking alcohol is a widespread habit in modern society and can have serious metabolic consequences. Recent studies have uncovered the interplay between nutrition, metabolism and circadian rhythms. But, until now, little has been done to understand the effects of alcohol consumption on circadian metabolism.

Coriell Institute for Medical Research wins $7.7 million NINDS contract

Coriell Institute for Medical Research has been awarded a $7.7 million contract by the National Institute of Neurological Disorders and Stroke, part of the National Institutes of Health focused on the study of nervous system disorders.

Teenage binge drinking may lead to anxiety and alcohol abuse in later life

Exposure to high levels of alcohol in adolescence may shape adult behaviors, predisposing them to a higher risk of anxiety and alcohol abuse later in life, a new study found.
