Abstract

Critical events in prostate tumorigenesis and metastasis likely include the abnormal activation and expression of specific genes. Using RNA expression profiling techniques, we have identified a transcript originating from the activated in prostate cancer (AIPC) gene, the expression of which is preferentially up-regulated in several cultured prostate tumor cell lines and human primary prostate tumors. Sequence analysis revealed that the AIPC protein encodes six PDZ domains, which are protein-protein binding domains likely involved in protein clustering and scaffolding. Immunohistochemical analysis of a tissue microarray comprising 158 tumor, 18 high-grade prostatic intraepithelial neoplasia, and 91 normal prostate specimens with an anti-AIPC antibody demonstrated abundant AIPC protein expression in 75% of tumors, 83% of prostatic intraepithelial neoplasia lesions, and 3% of normal tissues (P <0.0001). These data suggest that the accumulation of AIPC protein may be closely associated with the initiation or early promotion of prostate tumorigenesis.
