Oxidative stress: mechanism of cell death clarified

Dr. Marcus Conrad of the Institute of Clinical Molecular Biology and Tumor Genetics at the Helmholtz Zentrum Munchen has decrypted the molecular mechanism through which the death of cells is caused by oxidative stress.

New hope for treating common form of inherited neuromuscular disease

Treatments that ramp up production of the tiny "motors" that power cells may have promise for treating one of the most common forms of inherited neuromuscular disease, according to a report in the September Cell Metabolism, a Cell Press publication. Neuromuscular disorders caused by defects in those mitochondrial motors affect a large number of children and adults worldwide, but today remain without treatment, the researchers said.

New understanding of how white blood cell eosiniphils fights infection

U.S. and Swiss scientists have made a breakthrough in understanding how a type of white blood cell called the eosinophil may help the body to fight bacterial infections in the digestive tract, according to research published online this week in Nature Medicine

Scientists discover reservoir of mitochondrial DNA mutations present in the general population

Researchers at the University of Newcastle, England, and the Virginia Bioinformatics Institute at Virginia Tech in the United States have revealed a large reservoir of mitochondrial DNA mutations present in the general population. Clinical analysis of blood samples from almost 3,000 infants born in north Cumbria, England, showed that at least 1 in 200 individuals in the general public harbor mitochondrial DNA mutations that may lead to disease.

Researchers find key mechanism of cell damage in aging and disease

Researchers have taken a first snapshot of how a class of highly reactive molecules inflicts cellular damage as part of aging, heart disease, stroke, cancer, diabetes, kidney disease and Alzheimer's disease to name a few. According to a study published today in the journal Cell, researchers have discovered a tool that can monitor related damage and determine the degree to which antioxidant drugs effectively combat disease.

A global DNA barcode database

The idea of barcoding is familiar to many: in almost every supermarket the checkout operator shows the ticket labelled with a series of black bars to a laser scanner which responds with a beep; a computer analyses the code, identifies the product and the price is sent to the till.

Novel approach for treating mitochondrial disorders wins Kaye prize

A novel concept for the treatment of mitochondrial disorders using directed enzyme replacement therapy (DERT) has won for a Hebrew University of Jerusalem doctoral candidate one of this year's Kaye Innovation Awards. The awards were presented at this year's 71st meeting of the Hebrew University Board of Governors.

tRNA import occurs in humans - could lead to targeted therapies

Scientists have determined that human cells are able to shift important gene products into their own mitochondria, considered the power plants of cells. The finding could eventually lead to therapies for dozens of diseases.

Red wine antioxidant resveratrol kills cancer

Rochester researchers showed for the first time that a natural antioxidant found in grape skins and red wine can help destroy pancreatic cancer cells by reaching to the cell's core energy source, or mitochondria, and crippling its function.

Compound present naturally in grape skin fights the complications of diabetes

Research carried out by scientists at the Peninsula Medical School in the South West of England has found that resveratrol, a compound present naturally in grape skin, can protect against the cellular damage to blood vessels caused by high production of glucose in diabetes, according to a paper published in the science journal "Diabetes, Obesity and Metabolism" this week.
