Treating cancer: Biologists find gene that could stop tumors in their tracks
University of Iowa researchers have found a gene in a soil-dwelling amoeba that functions similarly to the main tumor-fighting gene found in humans, called PTEN. …

Mechanism promoting multiple DNA mutations described by scientists
However, recent studies have shown that cancer development frequently involves the formation of multiple mutations that arise simultaneously and in close proximity to each other. These groups of clustered mutations are frequently found in regions where chromosomal rearrangements take place. The discovery, published in the journal Cell Reports, may one day lead to new cancer therapies, according to a University of Iowa biologist and her colleagues, and a group of researchers from the National Institute of Environmental Health Sciences led by Senior Associate Scientist Dmitry Gordenin. The formation of clustered mutations may result from the process of DNA repair. …
