Mice study suggests novel approach to treat a type of common glioma

Gliomas are common brain tumors that comprise about one third of all cancers of the nervous system. In a study funded by the National Institutes of Health, researchers tested a novel combination treatment approach on mice with tumors with characteristics similar to human astrocytomas--a type of slow-growing glioma--and found tumor regression in 60 percent of the mice treated.

Kruppel-like factor 15 controls skeletal muscle fat uptake and utilization

Metabolic diseases, such as obesity and type 2 diabetes, have risen to epidemic proportions in the U.S. and occur in about 30 percent of the population. Skeletal muscle plays a prominent role in controlling the body's glucose levels, which is important for the development of metabolic diseases like diabetes.

Daily caffeine consumption can change the gray matter of the brain

Coffee, cola or an energy drink: caffeine is the world's most widely consumed psychoactive substance. Researchers from the University of Basel have now shown in a study that regular caffeine intake can change the gray matter of the brain. However, the effect appears to be temporary.

Scientists discover two unique subtypes of a prominent mutation in patients with AML

Using advanced RNA sequencing, scientists have identified two unique subtypes of a prominent mutation present in many patients with Acute Myeloid Leukemia (AML) – called NPM1 – that could help predict survival and improve treatment response for patients whose leukemic cells bear the mutation.

Genetic testing technology wrongly detects the presence of very rare genetic variants

A technology that is widely used by commercial genetic testing companies is "extremely unreliable" in detecting very rare variants, meaning results suggesting individuals carry rare disease-causing genetic variants are usually wrong, according to new research published in the BMJ.
