Researchers at the University of Michigan Medical School have identified a third gene involved in prostate cancer, expanding their groundbreaking announcement, published last October in Science, that the majority of prostate cancers carry a malignancy-inducing fusion of genes never before seen in solid tumors. The new findings appear in the April 1 issue of Cancer Research. Since prostate cancer is a cancer of the epithelial cells lining organs, lead researcher Arul Chinnaiyan and his colleagues believe it likely that other gene re-arrangements may be responsible for other cancers of epithelial tissue, including breast, colon and lung.
