SSTR5 and posterior cortical atrophy: In this study, we also had the opportunity to analyze in parallel the expression pattern of all SSTR-subtype by a quantitative PCR method in a representative cohort of PCa tissues, which revealed that SSTR1, SSTR2 and SSTR5 were highly expressed in PCa tissues (i.e., SSTR1 ≥ SSTR2 = SSTR5).
