Liver cancers are embedded with a type of super cancer stem cells that make them resistant to chemotherapy, spread to other body parts and stage a comeback even after they are surgically removed, researchers in Hong Kong reported on Thursday.

Researchers at King’s College London have found a molecule in the body which controls sensitivity to pain from UVB irradiation, identifying it as a new target for medicines to treat pain caused by other common inflammatory conditions such as arthritis.

Scientists have good reasons to be curious about the genome of the naked mole-rat. The mole-rat, found in the deserts of East Africa, can survive many years in a harsh environment and appears to be resistant to diseases of aging, including cancer. Studies suggest that the mole-rat cells have anti-tumor characteristics not found in other rodents.

Hepatocellular carcinoma (HCC), the most common type of liver cancer, is a leading cause of cancer-related deaths worldwide. Although there are several treatment options available, they are largely unsuccessful because the disease is so poorly understood.

SALT LAKE CITY — Watch a life-saving drug flow into the arm of a loved one who has cancer or reach for prescription medication to ease your allergies or lower your blood pressure and there's a good chance you owe some thanks to a fruit fly, a zebrafish or a mouse. Or maybe all of them.

Scientists at the National Institutes of Health have uncovered a pathway in mice that allows white fat — a contributor to obesity and type 2 diabetes — to burn calories in a way that’s normally found in brown fat and muscle. The findings are in the July 6 edition of Cell Metabolism.

Long-term exposure to air pollution can lead to physical changes in the brain, as well as learning and memory problems and even depression, new research in mice suggests.

A protein previously thought not to exist in adult human lungs not only is present in normal and cancerous lung tissue, scientists have found, but it also has a major role in the development of a lethal complication of some lung cancers.

Using a combination of genetic engineering and laser technology, researchers at the University of North Carolina at Chapel Hill have manipulated brain wiring responsible for reward-seeking behaviors, such as drug addiction. The work, conducted in rodent models, is the first to directly demonstrate the role of these specific connections in controlling behavior.

Rodent study identifies a key virus-sensing mechanism that is necessary for a successful immune response against infection with this particularly deadly type of virus. The research may help to guide the future design of more effective antiretroviral vaccines.

In a U.S. study, early safety tests suggested the eggs of pig whipworms have anti-inflammatory properties, reducing the size of brain lesions in MS patients.

For the first time, scientists have figured out how re-grow big chunks of human skeletal muscle by tricking the human body into accepting a biological matrix of pig proteins. If successful, this cellular regeneration method promises new life for injured war veterans and other trauma victims who are missing more than 25 percent of a limb and/or who face amputation.

Scientists have used a gene therapy tool that acts like intelligent molecular scissors to correct the key gene defect in mice with hemophilia B, a disease that can lead to uncontrolled bleeding. The intervention improved the animals’ blood clotting enough that their severe disease was reduced to a mild form.

Scientists have discovered the tool that bacteria normally found in our mouths use to invade heart tissue, causing a dangerous and sometimes lethal infection of the heart known as endocarditis.

Lithium profoundly prevents the aggregation of toxic proteins and cell loss associated with Parkinson’s disease (PD) in a mouse model of the condition.

A study in mice has pinpointed a pivotal new player in triggering the rapid antidepressant response produced by ketamine. By deactivating a little-known enzyme, the drug takes the brakes off rapid synthesis of a key growth factor thought to lift depression, say researchers supported by the National Institutes of Health.

A study led by researchers at the Joslin Diabetes Center suggests that adding the amino acid leucine to their diets may help those with pre-diabetes or metabolic syndrome.
