11/5/2012 7:25:56 AM
A University of Cincinnati (UC) cancer biology team reports breakthrough findings about specific cellular mechanisms that may help overcome endocrine (hormone) therapy-resistance in patients with estrogen-positive breast cancers, combating a widespread problem in effective medical management of the disease. Xiaoting Zhang, PhD, and his colleagues have identified a specific estrogen receptor co-activator -- known as MED1 -- as playing a central role in mediating tamoxifen resistance in human breast cancer. The team reports its findings in the Nov. 1, 2012, issue of Cancer Research, a scientific journal of the American Association for Cancer Research.
