Brief Description:

Our laboratory has cloned and initially characterized the expression of the mRNA encoding prostate-specific membrane antigen (PSMA); sequenced human and mouse PSMA DNA; generated PSMA-knockout and transgenic mice expressing PSMA in their prostates; identified and sequenced the closely related PSMA-like gene; identified the PSMA enhancer and evaluated a potential means of prodrug activation in gene therapy strategies; observed that PSMA is strongly expressed on all human tumor neovasculature; developed RT-PCR methods of detecting circulating human prostate cells; identified PSMA as a folate hydrolase and glutamate carboxypeptidase; elucidated the role of glycosidation and dimerization in PSMA’s enzymatic activity; and shown PSMA’s attenuation of cell invasiveness.

PSMA is strongly expressed on nearly all prostate cancer cells and on blood vessels in all solid tumors. Because prostate cancer is a leading cause of death in men, it is crucial that we pursue PSMA as a prime target for tumor treatment.

A number of fully human or humanized anti-PSMA antibodies linked to toxins are under clinical investigation as targeting vectors for cancer treatment, whether prostate cancer tumors or the tumor blood vessels of any other solid tumor.

We are also developing low-molecular-weight PSMA ligands for imaging. Thus our current focus is find means of targeting PSMA for therapy and/or imaging.
