African American men are diagnosed with prostate cancer more often and later in the disease than white men. Now researchers may have found the cause.
Researchers compared prostate cancer cells from 50 African American and Caucasian men. They found two proteins are over-produced in 90 percent of the tumor cells of African American men.
Researchers say these proteins are involved in prostate cancer aggression and might be used in the future to screen for the disease. The proteins are called hnRNP-H1 and SAFB-2.
The proteins are somehow involved in the relationship between hormones and prostate cancer progression.
