Key to aggressive breast cancer found

 "" PHOTO
"" ""

In trying to find out why HER2-positive breast cancer can be more aggressive than other forms of the disease, UC Davis Cancer Center researchers, led by Colleen Sweeney, associate professor of biochemistry and molecular medicine, discovered that HER2 shuts down its own regulator gene, creating a permissive environment for tumor growth. In addition to being more aggressive, HER2-positive breast cancer tends to be less responsive to currently available treatments. The finding could lead to new treatments aimed at restoring or replacing functions of the regulator. The study was published in Cancer Research.
