Could this widely used food additive cause celiac disease?

Myths about gluten are hard to bust. Intolerance, allergy, sensitivity, hypersensitivity. What is what? Celiac disease is none of these things. It is an autoimmune disorder, where gluten triggers the immune system to attack the gut. It is common, lifelong, and can seriously harm health — but nobody knows for sure what causes it. Now

Soil compound fights chronic wasting disease

A major compound in soil organic matter degrades chronic wasting disease prions and decreases infectivity in mice, according to a study published November 29 in the open-access journal PLOS Pathogens by Judd Aiken of the University of Alberta, and colleagues. Chronic wasting disease is an environmentally transmissible, fatal prion disease affecting free-ranging deer, moose, elk

Stress-induced effects on heart blood flow differ for men versus women

Some patients with coronary artery disease have inadequate blood flow to the heart muscle during periods of mental/emotional stress. This condition — called “mental stress-induced myocardial ischemia” (MSIMI) — is related to the severity of plaque buildup in the coronary arteries in men but not women, reports a study in Psychosomatic Medicine: Journal of Biobehavioral

Failing heart cells trigger self-protection mechanism: Stress transforms an important structural protein into a gene regulator that protects against heart failure

An unexpected finding that links a structural heart protein to gene regulation following heart stress suggests potential new avenues for developing heart failure therapies. The work led by University of Iowa heart researcher Long-Sheng Song, MD, focuses on a protein called junctophilin-2 (JP2). Previous work from Song’s lab has shown that JP2 is a structural

Sensory neurons can be used to discover therapies for ALS: New approach for testing for ALS may be useful to reverse debilitating disease

Virginia Tech Carilion Research Institute scientists have shown that mutations in specific genes that destroy motor neurons and thereby cause the devastating effects of amyotrophic lateral sclerosis — also known as ALS or Lou Gehrig’s disease — also attack sensory neurons. The discovery in today’s (Thursday, Nov. 8) Scientific Reports indicates that studying sensory neurons

New insights into the neural risks and benefits of marijuana use: Compounds in cannabis can impair or improve memory depending on age, disease

Research released today underscores both the dangers and the therapeutic promise of marijuana, revealing different effects across the lifespan. Marijuana exposure in the womb or during adolescence may disrupt learning and memory, damage communication between brain regions, and disturb levels of key neurotransmitters and metabolites in the brain. In Alzheimer’s disease, however, compounds found in

New devices to test retinal cells

Researchers at Utah State University have developed new devices to mechanically stress human cells in the lab. In a study published in Lab on a Chip, researchers Elizabeth Vargis, a USU assistant professor of biological engineering and Farhad Farjood, a Ph.D. student in Vargis’ Lab, wanted to better understand the triggers of age-related macular degeneration

Genetic disease healed using genome editing

Parents of newborns may be familiar with the metabolic disorder phenylketonuria: in Switzerland, all newborn babies are screened for this genetic disease. If a baby is found to have phenylketonuria, it needs a special diet so that the amino acid phenylalanine does not accumulate in the body. Excess phenylalanine delays mental and motor development. If

Caspase-2 enzyme inhibitor shows promise for ameliorating fatty liver disease: Researchers identify enzyme as responsible for onset and progression of fatty liver disease in mice and human clinical specimens

Researchers at University of California San Diego School of Medicine have discovered using mice and human clinical specimens, that caspase-2, a protein-cleaving enzyme, is a critical driver of non-alcoholic steatohepatitis (NASH), a chronic and aggressive liver condition. By identifying caspase-2’s critical role, they believe an inhibitor of this enzyme could provide an effective way to

Potential target for developing obesity and diabetes treatment identified

A newly published study by researchers from the University of Colorado School of Medicine has identified a potential therapeutic target for treating obesity and diabetes. The scientists studied the biological function of an epigenetic modifier known as histone deacetylase 11 (HDAC11), and determined that deleting it in mice stimulates the formation of brown adipose tissue.

Genetic basis of heart rhythms explored in large population study: Better treatments for atrial fibrillation and heart block could emerge from greater understanding of the heart’s electrical activity

New knowledge about biological processes related to the heart’s electrical activity has been gained through a major genome science study. The research had the largest sample size ever of a project of this type. The molecular mechanisms explored in this study offer insights into cardiac electrical diseases and could suggest avenues of drug research for

Next generation ALS drug silences inherited form of the disease in animal models: Preclinical study suggests drug may be ready for early stage clinical trials

NIH-funded researchers delayed signs of amyotrophic lateral sclerosis (ALS) in rodents by injecting them with a second-generation drug designed to silence the gene, superoxide dismutase 1 (SOD1). The results, published in the Journal of Clinical Investigation, suggest the newer version of the drug may be effective at treating an inherited form of the disease caused

Tickborne diseases are likely to increase, say NIAID officials

The incidence of tickborne infections in the United States has risen significantly within the past decade. It is imperative, therefore, that public health officials and scientists build a robust understanding of pathogenesis, design improved diagnostics, and develop preventive vaccines, according to a new commentary in the New England Journal of Medicine from leading scientists at

Progress toward improved Wilson’s disease drug

Researchers at Cold Spring Harbor Laboratory (CSHL), working in collaboration with DepYmed Inc., a CSHL spinout company, today report that they have conducted promising preclinical experiments on a compound that could be used to treat Wilson’s disease and possibly other disorders — including certain types of cancer — in which levels of copper in the
