Scientists at the Salk Institute have identified a gene responsible for stopping the movement of cancer from the lungs to other parts of the body, indicating a new way to fight one of the world’s deadliest cancers. By identifying the cause of this metastasis—which often happens quickly in lung cancer and results in a bleak survival rate—Salk scientists are able to explain why some tumors are more prone to spreading than others. The newly discovered pathway, detailed today in Molecular Cell, may also help researchers understand and treat the spread of melanoma and cervical cancers.

A chemical that's found in fruits and vegetables from strawberries to cucumbers appears to stop memory loss that accompanies Alzheimer's disease in mice, scientists at the Salk Institute for Biological Studies have discovered. In experiments on mice that normally develop Alzheimer's symptoms less than a year after birth, a daily dose of the compound----a flavonol called fisetin----prevented the progressive memory and learning impairments. The drug, however, did not alter the formation of amyloid plaques in the brain, accumulations of proteins which are commonly blamed for Alzheimer's disease. The new finding suggests a way to treat Alzheimer's symptoms independently of targeting amyloid plaques.

Highly diverse cancers share one trait: the capacity for endless cell division. Unregulated growth is due in large part to the fact that tumor cells can rebuild protective ends of their chromosomes, which are made of repeated DNA sequences and proteins. Normally, cell division halts once these structures, called telomeres, wear down. But cancer cells keep on going by deploying one of two strategies to reconstruct telomeres.

Cholesterol, for example, an important component of the membranes of cells, is a large isoprenoid chemical.

It was once thought that each cell in a person's body possesses the same DNA code and that the particular way the genome is read imparts cell function and defines the individual. For many cell types in our bodies, however, that is an oversimplification. Studies of neuronal genomes published in the past decade have turned up extra or missing chromosomes, or pieces of DNA that can copy and paste themselves throughout the genomes.

With the flick of a light switch, researchers at the Salk Institute for Biological Studies can change the shape of a protein in the brain of a mouse, turning on the protein at the precise moment they want. This allows the scientists to observe the exact effect of the protein's activation. The new method, described in the October 16 issue of the journal Neuron, relies on specially engineered amino acids----the molecules that make up proteins----and light from an LED. Now that it has been shown to work, the technique can be adapted to give researchers control of a wide variety of other proteins in the brain to study their functions.

Proteins are the workhorses of cells, adopting conformations that allow them to set off chemical reactions, send signals and transport materials. But when a scientist is designing a new drug, trying to visualize the processes inside cells, or probe how molecules interact with each other, they can't always find a protein that will do the job they want. Instead, they often engineer their own novel proteins to use in experiments, either from scratch or by altering existing molecules.

More than 11,000 Americans suffer spinal cord injuries each year, and since over a quarter of those injuries are due to falls, the number is likely to rise as the population ages. The reason so many of those injuries are permanently disabling is that the human body lacks the capacity to regenerate nerve fibers. The best our bodies can do is route the surviving tissue around the injury site.

Stem cells are key to the promise of regenerative medicine: the repair or replacement of injured tissues with custom grown substitutes. Essential to this process are induced pluripotent stem cells (iPSCs), which can be created from a patient's own tissues, thus eliminating the risk of immune rejection. However, Shinya Yamanaka's formula for iPSCs, for which he was awarded last year's Nobel Prize, uses a strict recipe that allows for limited variations in human cells, restricting their full potential for clinical application.
