PITTSBURGH, Nov. 1 — Nonsteroidal anti-inflammatory drugs (NSAIDs) prevent colon cancer by triggering diseased stem cells to self-destruct, according to researchers at the University of Pittsburgh Cancer Institute (UPCI) and the University of Pitts…
Like some people, cells eat when they are under pressure — but they consume parts of themselves. A multi-function protein helps control this form of cannibalism, according to a study in the September 6 issue of the Journal of Cell Biology (ww…
Researchers have found that a recently discovered gene plays an essential role in mediating apoptosis, or cell death, in colorectal cancer cells. The gene, PUMA, or p53 up-regulated modulator of apoptosis, is controlled by p53 ? a tumor-suppressing gene that prevents normal cells from turning into life-threatening tumor cells. Previous research has determined that damage to p53 is fundamental to the development of a vast majority of cancers, and inactivation of the growth-controlling function of p53 is critical to the growth and spread of most cancers.
