Scientists isolate genes that made 1918 flu lethal

By mixing and matching a contemporary flu virus with the "Spanish flu" - a virus that killed between 20 and 50 million people 90 years ago in history's most devastating outbreak of infectious disease - researchers have identified a set of three genes that helped underpin the extraordinary virulence of the 1918 virus.

Matrix fragments trigger fatal excitement

Shredded extracellular matrix (ECM) is toxic to neurons. Chen et al. reveal a new mechanism for how ECM demolition causes brain damage. The study will appear in the December 29, 2008 issue of The Journal of Cell Biology (www.jcb.org).

Diet high in inorganic phosphates increases risk of lung cancer

New research in an animal model suggests that a diet high in inorganic phosphates, which are found in a variety of processed foods including meats, cheeses, beverages, and bakery products, might speed growth of lung cancer tumors and may even contribute to the development of those tumors in individuals predisposed to the disease.

Scientists reverse brain birth defects using stem cell therapy

Scientists at the Hebrew University of Jerusalem have succeeded in reversing brain birth defects in animal models, using stem cells to replace defective brain cells.

Targeted nanoparticles deliver therapeutic DNA to cancer cells

Given that cancer is a disease caused by gene mutations, cancer researchers have been striving to develop gene therapies aimed at correcting these mutations. However, these efforts have been hobbled by the difficulty in safely and efficiently delivering anticancer genes to tumors. Nanoparticles, however, may solve these delivery issues, and two recently published studies, using two different types of nanoparticles, lend credence to that hypothesis.

Patient-derived induced stem cells retain disease traits

The dying cells - the same type lost in patients with the devastating neurological disease spinal muscular atrophy - confirmed that the University of Wisconsin-Madison stem cell biologist had recreated the hallmarks of a genetic disorder in the lab, using stem cells derived from a patient.

FDA approves Gleevec (imatinib mesylate) to prevent gastrointestinal stromal tumor

The U.S. Food and Drug Administration has approved Gleevec (imatinib mesylate) for a new indication – keeping cancer from growing in patients following surgical removal of a gastrointestinal stromal tumor or GIST.

Researchers identify gene linked to inherited form of fatal lung disease

Researchers at UT Southwestern Medical Center have determined that a mutation in a gene known for its role in defending the lungs against invading pathogens is responsible for some inherited cases of a lethal lung disease affecting older adults. The same mutation may also be associated with lung cancer, the researchers said.
