BACKGROUND Estrogen signaling is mediated by estrogen receptor beta isoforms in normal and neoplastic human testes. Recently, a G-protein-coupled-receptor (GPER) has been suggested as being involved in rapid responses to estrogens in different normal and tumor cells. METHODS This study investigated the GPER expression in paraffin-embedded samples from non neoplastic and neoplastic human teste...
