For someone with a severe, incurable lung disorder such as cystic fibrosis or chronic obstructive pulmonary disease, a lung transplant may be the only chance for survival. Unfortunately, it’s often not a very good chance. Matching donor lungs are rare, and many would-be recipients die waiting for the transplants that could save their lives.

Building on research work undertaken in Germany, City of Hope investigators near LA have used modified stem cells loaded with gene sequences to fight off HIV. And the scientists in the study say that the work points to a possible cure for the dread virus, which has killed millions of people around the world.

While the overall economy may be flagging, Maryland says that its biotech industry is booming. And the governor wants to keep the momentum going with a few new industry incentives. Gov. Martin O’Malley told reporters that the biotech industry added more than a thousand jobs in the last three months; that’s 10 percent of the state’s total tally of new jobs. And he touted a report from Battelle Technology Partnership Practice claiming that the state’s biotech industry has been expanding aggressively for the last several years.

Craig Venter has never been reluctant to credit himself for a lead role in sequencing the human genome. And he’s certainly not the least bit shy about placing a high value on the overall significance of the work. “I think it’s far more important than walking on the Moon; not much has happened since walking on the Moon,” he tells the BBC on the tenth anniversary of the grand achievement, which took 2,000 scientists more than 10 years and $2.7 billion to accomplish.

Lithium is the most effective treatment for bipolar disorder. However, its use is limited because of neurological side effects and a risk for overdose-induced toxicity. Many of the beneficial effects of lithium are mediated by its inhibition of GSK-3 proteins, but whether this is the mechanism underlying its negative effects has not been determined. However, Raquel Gómez-Sintes and José Lucas, at CSIC/UAM, Spain, have now delineated a molecular pathway by which chronic administration of therapeutic doses of lithium has negative effects in mice.

With thousands of scientists across the globe searching for ways to use adult stem cells to fight disease, there’s a growing emphasis on finding the “master regulators” that guide the differentiation of stem cells. New research from Rice University and the University of Cambridge suggests that a closely connected trio of regulatory proteins fulfills that role in hematopoietic stem cells (HSCs), the self-renewing cells the body uses to make new blood cells.

The recently enacted healthcare reform legislation provides up to $1 billion in tax credits and cash grants for life sciences companies with 250 or fewer employees that have made or will make “qualified investments” in “qualifying therapeutic discovery projects” during 2009 and 2010. Credits and grants will be awarded through a competitive application process which is expected to commence on or before May 21, 2010.

The molecular machinery that switches on a gene known to cause breast cancer to spread and invade other organs has been identified by an international team led by scientists at The University of Texas M. D. Anderson Cancer Center. The paper was published in Nature Cell Biology’s advanced online publication.

Infectious diseases are not always caused by infection. In work reported in the Journal of Experimental Medicine, researchers at Rockefeller University reveal that patients who suffer from a rare autoimmune disorder that makes them vulnerable to yeast infections produce antibodies that target and destroy immune-fighting proteins that would otherwise keep yeast in check.

A team of McGill Chemistry Department researchers led by Dr. Hanadi Sleiman has achieved a major breakthrough in the development of nanotubes — tiny “magic bullets” that could one day deliver drugs to specific diseased cells. Sleiman explains that the research involves taking DNA out of its biological context. So rather than being used as the genetic code for life, it becomes a kind of building block for tiny nanometre-scale objects.
