Prostate cancer is the second most common cause of cancer death in American men. Once metastasis has occurred, there is no curative treatment, and the search for effective therapies for prostate cancer and, in particular, for metastasis to bone is hampered by a lack of suitable animal models of the disease.
In this issue of the Journal, Nemeth et al. (1) address aspects of these two difficult issues. They describe the use of the human fetal bone/severe combined immunodeficient (SCID) mouse model to explore the role of matrix metalloproteinases (MMPs) in metastasis of prostate cancer to bone and the ability of the broad-spectrum MMP inhibitor batimastat to reduce bone disease.
Most research into human prostate cancer uses just three cell lines, PC3, DU-145, and LnCaP. After subcutaneous inoculation into immunocompromised
