Molecular biology of prostate development and prostate cancer.

The molecular mechanisms that control prostate development have been intensely studied in recent years due to the emergence of prostatic cancer as a major health concern. Several recent studies have led to the identification of numerous genes that are required for prostate organogenesis, many of which also contribute to prostate carcinogenesis. These genes fall into several categories, including proto-oncogenes, transcription factors, homeobox genes, growth factors and cell adhesion molecules. This review focuses on those genes which have been implicated in prostate growth and development, and which exhibit deregulated expression in prostate cancer.
