Gene expression studies were performed using a commercial cDNA-array from Superarray that contains a limited number of genes (96 genes) related to drug metabolism, and a custom-made cDNA microarray that contains a higher number of genes (300 genes, including some genes from Superarray) related to mechanisms of carcinogenesis or chemoprevention. Real-time PCR and enzyme activity assays were additionally performed to confirm selected array results.
For example, men identified as high risk might elect to embark on a program of risk reduction through diet and lifestyle modification along with chemoprevention using finasteride, which has been shown to reduce prostate cancer risk by about 25%.
