New study investigates Ebola protein

A new study by Robert Stahelin, an adjunct associate professor of chemistry and biochemistry at the University of Notre Dame and an associate professor at the Indiana University School of Medicine-South Bend, as well as a member of Notre Dame's Eck Institute for Global Health, investigates how the most abundant protein that composes the Ebola virus, VP 40, mediates replication of a new viral particle.

Male hormone testosterone may increase risk of colon cancer

Previous cancer research has revealed that women are less likely than men to suffer from non-sex specific cancers such as cancer of the colon, pancreas and stomach. Scientists theorized that perhaps this trend was due to a protecting effect created by female hormones, such as estrogen, that help prevent tumors from forming. Now, researchers at the University of Missouri have found evidence suggesting that the male hormone testosterone may actually be a contributing factor in the formation of colon cancer tumors.

New technique allows rapid, large-scale studies of gene function

Using a gene-editing system originally developed to delete specific genes, MIT researchers have now shown that they can reliably turn on any gene of their choosing in living cells.

Stem cells from healthy eye could one day be used to repair scarred cornea

Treating the potentially blinding haze of a scar on the cornea might be as straightforward as growing stem cells from a tiny biopsy of the patient's undamaged eye and then placing them on the injury site, according to mouse model experiments conducted by researchers at the University of Pittsburgh School of Medicine.

CUMC researchers devise way to replace torn knee meniscus

Columbia University Medical Center researchers have devised a way to replace the knee's protective lining, called the meniscus, using a personalized 3D-printed implant, or scaffold, infused with human growth factors that prompt the body to regenerate the lining on its own.

NYSCF, CMTA partner to advance research on genetic neuropathies

The New York Stem Cell Foundation Research Institute, a non-profit organization dedicated to accelerating cures through stem cell research, announced a collaboration today with the Charcot-Marie-Tooth Association, a patient-led disease foundation with the mission to advance research on genetic neuropathies that leads to the development of new therapies.

Johns Hopkins study shows gene expression in autism brains

While many different combinations of genetic traits can cause autism, brains affected by autism share a pattern of ramped-up immune responses, an analysis of data from autopsied human brains reveals. The study, a collaborative effort between Johns Hopkins and the University of Alabama at Birmingham, included data from 72 autism and control brains.

Alcohol consumption interferes with sleep homeostasis

Researchers from the University of Missouri School of Medicine have found that drinking alcohol to fall asleep interferes with sleep homeostasis, the body's sleep-regulating mechanism.

New study reveals how COX-2 inhibitors can increase risk of heart attack in arthritis patients

A class of drug for treating arthritis - all but shelved over fears about side effects - may be given a new lease of life, following the discovery of a possible way to identify which patients should avoid using it.

Enzymatic activity essential for vision may provide target for drug transport

Researchers at Case Western Reserve University School of Medicine have uncovered the mechanism that enables the enzyme Lecithin: retinol acyltransferase (LRAT) to store vitamin A--a process that is indispensable for vision.

Simple supplement could reduce heart disease in individuals born with low birth weight

A simple supplement could be a safe and cost-effective way of reducing heart disease in individuals born with a low birth weight, suggests research from the University of Cambridge. The study, carried out in rats, also raises the possibility of developing a blood test to indicate how much damage there is in the aortas of these individuals.

Study brings researchers closer to understanding how brains work

Whether we're paying attention to something we see can be discerned by monitoring the firings of specific groups of brain cells. Now, new work from Johns Hopkins shows that the same holds true for the sense of touch. The study brings researchers closer to understanding how animals' thoughts and feelings affect their perception of external stimuli.

Study: Long-term endurance training alters epigenetic pattern in the human skeletal muscle

A new study from Karolinska Institutet in Sweden shows that long-term endurance training in a stable way alters the epigenetic pattern in the human skeletal muscle. The research team behind the study, which is being published in the journal Epigenetics, also found strong links between these altered epigenetic patterns and the activity in genes controlling improved metabolism and inflammation.

Scientists develop new technique to get detailed images of mouse neurons

Scientists can now explore nerves in mice in much greater detail than ever before, thanks to an approach developed by scientists at the European Molecular Biology Laboratory in Monterotondo, Italy. The work, published online today in Nature Methods, enables researchers to easily use artificial tags, broadening the range of what they can study and vastly increasing image resolution.

Variations in ERAP1 enzyme could lead to Ankylosing Spondylitis

Scientists at the University of Southampton have discovered variations in an enzyme belonging to the immune system that leaves individuals susceptible to Ankylosing Spondylitis.

Genetic variations may contribute to treatment-related cognitive problems in children with ALL

Common variations in four genes related to brain inflammation or cells' response to damage from oxidation may contribute to the problems with memory, learning and other cognitive functions seen in children treated for acute lymphoblastic leukemia (ALL), according to a study led by researchers from Boston Children's Hospital, The Children's Hospital at Montefiore, and Dana-Farber/Boston Children's Cancer and Blood Disorders Center.

Heat-shock protein 90 enables ER+ breast cancers to develop resistance to hormonal therapy

Long known for its ability to help organisms successfully adapt to environmentally stressful conditions, the highly conserved molecular chaperone heat-shock protein 90 (HSP90) also enables estrogen receptor-positive (ER+) breast cancers to develop resistance to hormonal therapy.

McGill University scientists show how simple potato extract can fight obesity

Take a look in your pantry: the miracle ingredient for fighting obesity may already be there. A simple potato extract may limit weight gain from a diet that is high in fat and refined carbohydrates, according to scientists at McGill University. The results of their recent study were so surprising that the investigators repeated the experiment just to be sure.
