Blocking protein kills prostate cancer cells, inhibits tumor growth, Jefferson scientists find
Date:2/27/2008

s. That way, she says, the hypothesis could be tested in real human prostate cancer tissue specimens.

While she and her team continue to work on establishing Stat5 as a therapeutic target for hormone-resistant prostate cancer, they are also testing whether or not blocking Stat5 can make prostate cancer cells more sensitive to other treatments, such as radiation and chemotherapy. Another next step in the work, Dr. Nevalainen says, is to find pharmacological agents that inhibit the protein.

In work reported recently in Cancer Research, Dr. Nevalainen and her co-workers showed that Stat5 is turned on in nearly all recurrent prostate cancers that are resistant to hormone therapy. In addition, the researchers also showed that the convergence of Stat5 and androgen receptor could be responsible for making such prostate cancers especially dangerous.
