Brain's neural activity plays a role in human aging, life span

The brain's neural activity - long implicated in disorders ranging from dementia to epilepsy - also plays a role in human aging and life span, according to research led by scientists in the Blavatnik Institute at Harvard Medical School.

Study reveals new and surprising function of adenine nucleotide translocator

Mutations in the gene that encodes a protein called adenine nucleotide translocator (ANT) cause a variety of conditions, such as heart disease and weakness of the eye muscles, but the underlying mechanism of how these mutations trigger disease has been unclear.

Researchers identify circuit that links cigarette smoking and risk of developing diabetes

Researchers from the Icahn School of Medicine at Mount Sinai have discovered a circuit in rats that links cigarette smoking and the risk of developing type 2 diabetes, according to a study featured on the cover of the October 17 issue of Nature.

Young blood may hold the key to treating age-related diseases

In what sounds like a scene from a science fiction movie, researchers in 2005 stitched together old and young mice so they shared a circulatory system.

Epigenetic changes can lead to development of GISTs, other cancers

Most cases of gastrointestinal stromal tumor (GIST), a type of soft-tissue cancer (sarcoma), are caused by mutations in genes that can be effectively targeted with drugs that inhibit the activity of rogue cancer-promoting enzymes.

Scientists discover novel virus that may shed light on viral evolution

Viruses are non-living creatures, consisting of genetic material encased in a protein coat. Once the virus infects a living organism, it can replicate itself and continue on. But what happens if a virus lacks the proper tools to infect an organism? How can it propagate?

Subtle changes in mitochondrial DNA can have profound consequences for patient's health

Subtle changes in the DNA of mitochondria, the tiny power plants within cells, can have profound consequences for a patient's health.

Scientists discover how malaria switched host from African gorillas to humans

Researchers have revealed the series of events that probably led to the world’s deadliest form of malaria being able to jump from ancient great apes to humans.

Study: Natural loss of foot muscles in rodents shares similarities with skeletal muscle atrophy

New insight on how the natural loss of foot muscles occurred in rodents and other species during their evolution has been published today in the open-access journal eLife.

Researcher explores biological processes that cause fertility problems in humans

With significant funding from the National Institutes of Health (NIH), a researcher at The University of Texas at Arlington is investigating fundamental biological processes that lead to fertility problems in humans.

Study: Genetic differences in the immune system shape bacteria that colonize the digestive system

Genetic differences in the immune system shape the collections of bacteria that colonize the digestive system, according to new research by scientists at the University of Chicago.

Koalas protect their germline cells against retroviral attack

In a new study published in the journal Cell, scientists have found that koala DNA is protected against attack by retroviruses by a special type of immune response, which distinguishes foreign DNA from the host genome and destroys it before it can proliferate. This finding could help us understand both how koalas survive these infections, and the mechanics of adaptive gene change.

CRISPR helps find difficult to detect cancer cells

Immunotherapy is one of the latest and most effective armaments against various types of cancers. Some of the immunotherapy drugs such as PD-1 inhibitor Keytruda from Merck can block certain proteins in the cancer cells that can make the cells invisible to the immune system normally. Some of the cancers cells can now develop other ways to disguise themselves from being killed by the immune system.

New molecular "clock" could help monitor life-altering development disorders in children

Scientists have developed a molecular "clock" that could reshape how pediatricians measure and monitor childhood growth and potentially allow for an earlier diagnosis of life-altering development disorders.

UCLA researchers discover new way to eliminate leukemia stem cells

The introduction of the drug imatinib in 2001 revolutionized the treatment of a type of cancer called chronic myelogenous leukemia. In more than 80% of people with CML who received the drug, the disease went into complete remission.

Researchers reveal mechanism involved in altering DNA methylation in cancer

Understanding the mechanisms that mediate widespread DNA damage in the cancer genome is of great interest to cancer physicians and scientists because it may lead to improved treatments and diagnosis. In this study, a multi-institutional team led by researchers at Baylor College of Medicine has brought attention to genomic structural variation as a previously unappreciated mechanism involved in altering DNA methylation, a form of gene control, in human cancers.

Discovery could lead to new therapeutic targets for neurodegenerative diseases

Research led by Drs. Miguel Burguillos (University of Seville, Spain) and Miguel Branco (Queen Mary University of London, UK), has revealed new findings about mechanisms regulating brain inflammation which open a new pathway in the field of neuroinflammation.

Finnish study offers new information about molecular mechanisms of Alzheimer's disease

Researchers have discovered new changes in blood samples associated with Alzheimer's disease. A new international study was conducted on disease-discordant Finnish twin pairs: one sibling suffering from Alzheimer's disease and the other being cognitively healthy.
