Team Finds New Genetic Anomalies in Lung Cancer

December 22, 2014 10:56 am | News | Comments

Developing effective treatments for lung cancer has been challenging, in part because so many genetic mutations play a role in the disease. By analyzing the DNA and RNA of lung cancers, researchers at the University of Michigan Comprehensive Cancer Center found that patients whose tumors contained a large number of gene fusions had worse outcomes than patients with fewer gene fusions.

Bacteria in Gut May Depend More on Diet than Genes

Reading Leaves a Dramatic Imprint on the Brain

December 17, 2014 4:23 pm | by Cynthia Fox, Science Writer | Articles | Comments

A good book recreates the world so robustly that it activates some of the same brain regions that “everyday life” does, according to a recent PLOS One study. In the study, innovative MRI analyses of people reading a richly imaginative book showed movement of characters occurring in a brain region where others’ motions are processed in the real world.

Insight Into How Brain Motor Neurons Die During ALS

December 17, 2014 4:13 pm | by Thomas Jefferson University | News | Comments

Researchers look to understand the causes of amyotrophic lateral sclerosis (ALS), in the hope of finding new ways to treat the disease. A new study published online in the Cell Press journal Neuron shows that a common gene mutation in ALS generates a deadly protein that may cause the damage in the brain that leads to ALS.

Stem Cells Faulty in Duchenne Muscular Dystrophy

December 17, 2014 4:03 pm | by Stanford University | News | Comments

Like human patients, mice with a form of Duchenne muscular dystrophy undergo progressive muscle degeneration and accumulate connective tissue as they age. Now, researchers at the Stanford University School of Medicine have found that the fault may lie at least partly in the stem cells that surround the muscle fibers.

Interactions Between Proteins Govern Tumor Suppression, Aging

December 16, 2014 12:54 pm | by UC Davis | News | Comments

Scientists have long known the p53 protein suppresses tumors. However, a recent animal study by UC Davis researchers has uncovered a complicated relationship between p53 and another protein, Rbm38, highlighting how the body calibrates protein levels. Too much Rbm38 reduces p53 levels, increasing the risk of cancer. Too little Rbm38 allows p53 overexpression, causing premature aging.
