The Expanding Role of Epigenetics in the Development, Diagnosis and Treatment of Prostate Cancer and Benign Prostatic Hyperplasia
2007
Purpose: Prostate cancer research has focused significant attention on the mutation, deletion or amplification of the DNA base sequence that encodes critical growth or suppressor genes. However, these changes have left significant gaps in our understanding of the development and progression of disease. It has become clear that epigenetic changes or modifications that influence phenotype without altering the genotype present a new and entirely different mechanism for gene regulation. Several interrelated epigenetic modifications that are altered in abnormal growth states are DNA methylation changes, histone modifications and genomic imprinting. We discuss the status of epigenetic alterations in prostate cancer and benign prostatic hyperplasia progression. In addition, the rationale and status of ongoing clinical trials altering epigenetic processes in urological diseases are reviewed.Materials and Methods: An online search of current and past peer reviewed literature on DNA methylation, histone acetylation...
