Mouse models of prostate cancer

The pathogenetic basis of prostate cancer remains highly elusive; its clarification could be facilitated greatly by laboratory and clinical models of the disease. Although the genetically manipulated mouse has been invaluable for the modeling of other human cancer types, it has fared less well with respect to prostate cancer. Nevertheless, several highly valuable transgenic models exist and are highlighted in this review. Emerging reagents and strategies may allow us to use the mouse more effectively to define the molecular, cellular and physiological events that lead to prostate cancer initiation and progression.
