Protein May Be Key To Prostate Cancer

Scientists say they have zeroed in on a new target in the fight against aggressive prostate cancer.Researchers at Georgetown University’s Lombardi Comprehensive Cancer Center say prostate cancer is much more likely to be aggressive if a key protein called Stat5 is both plentiful and active within cancer cells.Their study found that active Stat5 protein was highly concentrated in aggressive prostate cancers. The protein is thought to send cellular signals prompting cancer growth.
