Scientists Discover Reasons Behind Cancerous Cellular Interactions (12/16/2007)

Cellular processes, such as when to multiply, are often regulated by switches that control the frequency and timing of interactions between proteins. North Carolina State University scientists have discovered the way in which a specific protein-protein interaction prevents the cell from turning one of its switches off, leading to uncontrolled cell proliferation - one of the hallmarks of cancer. ...> Full Article

Most carriers of Fanconi anemia genes are not at a higher risk of cancer (12/15/2007)

For almost 50 years, Fanconi anemia has been associated with leukemia. Not just among those who have the genetic disorder but among their family members, whose genes, they were told, made them highly susceptible to a variety of malignancies. But a new study to examine links between 13 specific Fanconi anemia genes and cancer risk has determined that in most cases, their risk of cancer is no greater than that of the rest of the population. ...> Full Article

How the anthrax bacterium eludes our immune defenses (12/14/2007)

After having demonstrated the protective role of one of the enzymes of our natural immunity of against B. anthracis, the anthrax bacterium, researchers from the Institut Pasteur, INSERM, and the CNRS explain how the bacillus is capable of evading the bactericidal action of this enzyme: this bacterium produces a toxin that inhibits the enzyme synthesis. This research*, published in PloS Pathogens, reveals potential new therapeutic avenues against anthrax. ...> Full Article
