Googling "SNARE proteins," neuroscientist Edward Chapman gets a screenful of images showing corkscrew-shaped molecules, intertwined as they seize the outer membranes of two cells. "They did not give us credit at Wikipedia, but we drew that cartoon," he says, with delicious irony. "And now we've proven that this model is wrong," he says. "The textbooks need to be adjusted."
A pandemic flu outbreak could kill millions. Now, researchers have found features of the virus's genome that influence how well it multiplies. The findings could help target pandemic flu surveillance efforts to make it easier to find the next outbreak before it spreads widely.
In breakthrough colon cancer research, scientists at Christiana Care Health System’s Center for Translational Cancer Research (CTCR) of the Helen F. Graham Cancer Center & Research Institute have discovered that over-expression of HOXA4 and HOXA9 genes in colon cancer stem cells promotes cell replication and contributes to the overpopulation of stem cells that drives colon cancer development. The findings suggest treatment with vitamin A derivatives, called retinoid drugs, could provide a therapeutic strategy for decreasing the expression of these HOX genes and for targeting highly resistant cancer stem cells.

Castleman disease, a rare disorder of the lymph nodes and related tissues, was identified and named more than a half-century ago but, until recently, no one had written a book exclusively about it. Frits van Rhee, M.D., Ph.D., professor of medicine and director of developmental and translational medicine at the Myeloma Institute at the University of Arkansas for Medical Sciences (UAMS), has changed that.
New drugs that activate the immune system to target cancer cells have improved the lives of many patients with cancer. However, immunotherapies are not effective in all patients, and the success of these therapies depends on individual patient factors. A team of Moffitt Cancer Center researchers is trying to find new ways to further enhance the activity of the immune system against cancer. In an article published in the January issue of Cancer Cell, the researchers describe how a new type of immunotherapy drug targeting the protein TIM-3 works to stimulate the immune system.
Amyloid plaques have long been believed to be an indicator of neurodegenerative disease.

People with the rare genetic disease primary ciliary dyskinesia suffer repeated lung infections because they lack functional cilia, hairlike structures that sweep mucus through the airways. Most people have errors in the molecular motor that powers the cilia. But some have errors in non-motor proteins. Now, Washington University School of Medicine in St. Louis researchers report that mutated non-motor proteins cause disease by assembling the motor incorrectly. The findings suggest new routes to drug discovery.

Doctors have long treated heart attacks, improved asthma symptoms, and cured impotence by increasing levels of a single molecule in the body: nitric oxide. The tiny molecule can change how proteins function. But new research featured in Molecular Cell suggests supplementing nitric oxide—NO—is only the first step. Researchers have discovered previously unknown enzymes in the body that convert NO into “stopgap” molecules—SNOs—that then modulate proteins. The newly discovered enzymes help NO have diverse roles in cells. They may also be prime therapeutic targets to treat a range of diseases.
