Immunohistochemical evaluation of ERG expression in various benign and malignant tissues.

The transmembrane protease, serine 2-E twenty-six related gene (TMPRSS2-ERG) fusion leading to ERG overexpression, was detected in approximately 50% of prostate cancers (ranging from 35-70%). However, the published data on ERG expression in tumors from other organs and normal tissues were limited. In this study, we investigated the expression of ERG in TMA sections of various normal tissues (N=452) and carcinomas (N=1,129) from various organs,...
