Gene May Help Spur Breast Cancer's Spread

Multiple copies of a gene called uPAR are associated with the spread of early-stage breast cancer, U.S. researchers report. The gene offers a promising target for drugs to slow or halt the progression of the disease... It could also serve as a screening tool for determining which kinds of drugs a breast cancer patient will respond to, the researchers said. The study was published in this week's issue of the Proceedings of the National Academy of Sciences. The researchers analyzed individual tumor cells from 72 patients with advanced breast cancer. They found that about 20 percent to 25 percent of breast cancer patients carry too many copies of the uPAR gene, which starts a process that allows cancer cells to escape into the bloodstream and to adjacent tissues. --Click the title of this post to read the full article from its source--
