2004 OCT 7 - (NewsRx.com & NewsRx.net) -- Scientists have recently discovered that the gene EDD is implicated in the development of breast and ovarian cancer.
"Cancer arises from defects in cell growth and division. We are now beginning to realize that defective cellular communication can also lead to cancer," says Rob Sutherland, director of the Cancer Research Program at the Garvan Institute in Australia.
Cells "talk" to each other in the developing embryo to coordinate themselves into higher structures like organs and blood vessels. Vigilant communication and coordination between cells is essential throughout life to maintain these structures. Part of EDD's job is to tell cells where to go.
Garvan scientists have shown that mice without EDD have the cells to make blood vessels, but they are unable to coordinate their development. Without EDD cells become confused.
Cancer is often caused by cells producing too many copies of key cancer genes. Work at Garvan has demonstrated that excess copies of the EDD gene are present in 73% of one aggressive type of ovarian cancer and that excessive amounts of the EDD protein are found in 63% of breast cancers and 39% of ovarian cancers. The ...
