| Approved cancer drug potentially could help treat diabetes Posted: 15 Sep 2013 10:43 AM PDT Scientists have identified a molecular pathway -- a series of interaction among proteins -- involved in the development of diabetes.  |
| Posted: 15 Sep 2013 10:42 AM PDT Cancer tumors almost never share the exact same genetic mutations, a fact that has confounded scientific efforts to better categorize cancer types and develop more targeted, effective treatments. Researchers propose a new approach called network-based stratification, which identifies cancer subtypes not by the singular mutations of individual patients, but by how those mutations affect shared genetic networks or systems.  |
| Pinpointing the molecular path that makes antidepressants act quicker Posted: 14 Sep 2013 06:33 AM PDT The reasons behind why it often takes people several weeks to feel the effect of newly prescribed antidepressants remains somewhat of a mystery – and likely, a frustration to both patients and physicians. How an antidepressant works on the biochemistry and behavior in mice lets researchers tease out the relative influence of two brain proteins on the pharmacology of an antidepressant. They found increased nerve-cell generation in the hippocampus and a quicker response to the antidepressant.  |
| Insulin plays role in mediating worms' perceptions and behaviors Posted: 13 Sep 2013 05:54 AM PDT In the past few years, as imaging tools and techniques have improved, scientists have been working tirelessly to build a detailed map of neural connections in the human brain -- with the ultimate hope of understanding how the mind works.  |
