Autism spectrum disorder and intellectual disability often occur together and may even share similar genetic causes. Researchers reporting in the Cell Press journal Cell Reports have now linked mutations in a particular gene to the two disorders in humans. By revealing these genetic changes and their potential impact on common brain processes, researchers may uncover treatment approaches that could benefit a variety of patients.

Many patients with advanced stages of cancer, AIDS, tuberculosis, and other diseases die from a condition called cachexia, which is characterized as a “wasting” syndrome that causes extreme thinness with muscle weakness. Cachexia is the direct cause of roughly 20% of deaths in cancer patients. While boosting food intake doesn’t help, and no effective therapies are available, new research in the Cell Press journal Cell Metabolism points to a promising strategy that may stimulate weight gain and muscle strength.

Scientists have designed a new self-assembling nanoparticle that targets tumours, to help doctors diagnose cancer earlier. The new nanoparticle, developed by researchers at Imperial College London, boosts the effectiveness of Magnetic Resonance Imaging (MRI) scanning by specifically seeking out receptors that are found in cancerous cells.

A brain region that is vital for memory and shrinks in Alzheimer’s disease patients also is likely to be smaller in those whose white blood cells have shorter DNA-protecting end caps – called telomeres – according to a study by Stanford and UC San Francisco researchers published online July 14, 2014 in the journal JAMA Neurology.

The drug letrozole results in higher birth rates in women with polycystic ovary syndrome (PCOS) than the current preferred infertility treatment drug, according to a nationwide study led by Penn State College of Medicine researchers.

Researchers from the Broad Institute and elsewhere have identified novel mutations in a well-known cancer-causing pathway in lung adenocarcinoma, the most common subtype of lung cancer. Knowledge of these mutations could potentially identify a greater number of patients with treatable mutations because many potent cancer drugs that target these mutations already exist. In addition, these findings may expand the number of possible new therapeutic targets for this disease.
