Method Discovered For Clamping Down On A Cancer-Promoting Enzyme
There are many pathways that allow an errant gene to turn a cell cancerous, and a number of these pathways go through a single enzyme called the p21-activated kinase 1, or PAK1.
Researchers at Fox Chase Cancer Center have now identified a molecule capable of shutting down PAK1 before the enzyme becomes active. Previous studies have linked PAK1 activity with breast cancer and have shown the enzyme is important in pathways involving the ras oncogene, which is thought to cause up to 30 percent of all cancers.
