A histone post-translational modification linked to lifelong susceptibility to stress in mice

Chemical changes to histones, the proteins that help to pack and organize DNA inside cells, play a key role in determining what genes will be consistently activated over the course of an animal or human's life. Past studies ...

PFAS exposure linked to sleep disruptions in young adults

Research led by the Keck School of Medicine of USC has shown that levels of "forever chemicals" in the blood are linked with disruptions to a fundamental pillar of health—sleep.

Gene activation linked to severity of a rare lung cancer

Pulmonary carcinoids are rare tumors of the lung with extremely different clinical courses. In many patients, they behave like benign tumors; surgical removal of the tumor leads to a complete cure. However, some patients ...

Categorizing the epigenetic hallmarks that define cancer

Cancer mortality has just surpassed cardiovascular disease for the first time ever and one in two men, and one in three women, will be diagnosed with some form of the disease in the US, according to the NIH.

New hope for blinding eye disease gene therapies

New opportunities towards gene therapy and diagnosis for the blinding eye disease, retinal dystrophy, may now become available following work done by the Eye Genetics Research Unit at Children's Medical Research Institute.

Sudden, unexplained child deaths often have a genetic cause

When a baby or toddler dies without warning, parents often blame themselves. A study at Boston Children's may provide some insight into sudden, unexplained child deaths and perhaps a measure of closure. It suggests that at ...

Genetics

Opioids and the brain: New insights through epigenetics

Drug overdose, mostly from opioid use, is the leading cause of accidental death in the United States. Prior studies of twins have revealed that genetics play a key role in opioid use disorder. Researchers know that a mixture ...

Researchers identify gene mutations linked to pregnancy sickness

Most women experience nausea and vomiting during pregnancy, but a condition known as hyperemesis gravidarum (HG), which affects up to 2% of pregnant women, causes nausea and vomiting so severe that it can lead to starvation, ...

Genetics

The sex of your cells matters when it comes to heart disease

Most mammals, including humans, have two sex chromosomes, X and Y. One sex chromosome is usually inherited from each parent, and they pair up as either XX or XY in every cell of the body. People with XX chromosomes typically ...

Genetics

When and how mutant clones expand in normal endometrium

Monthly menstruation is a biological phenomenon in women of reproductive age that involves morphological and functional changes in the uterine endometrium followed by uterine lining shedding. The endometrial layer can regenerate ...

Genetics

Big US gene database has volunteers from all walks of life

Scientists are getting their first peek at the genes of nearly 100,000 Americans in what's considered a uniquely diverse genomic database—part of a quest to reduce health disparities and end cookie-cutter care.

Genetics

Study identifies genetic markers related to leadership

A new study led by the National University of Singapore (NUS) Business School has identified the locations of nine significant genetic markers associated with leadership. For the first time, this allows researchers to examine ...

Hope for breast cancer patients, but with a cruel caveat

The clinical trial of an old antibiotic for a new purpose is offering hope to thousands of patients with drug-resistant breast cancer whose early remissions have given way to resurgent tumors.

Scientists create novel genetic model of Down syndrome in rats

In pursuit of better ways to test new therapies and further explore the impacts of the unique genetics associated with Down syndrome, researchers at Johns Hopkins Medicine and Tottori University in Japan have genetically ...

Genetics

'Roadmap' tracks trajectories of embryo development

Scientists have mapped out the key molecular changes that orchestrate how embryonic mouse cells differentiate into the diverse cell types that will ultimately form all the different tissues and organs of the adult animal.
