SSTR2 and Familial prostate cancer: While expression of SSTR3 (mean normalized expression value ± SD: 59.7±30.1 [normal] vs. 76.2±89.1 [cancer], p>0.05) and SSTR5 (226.3±47.1 [normal] vs. 236.1±50.6 [cancer], p>0.05) did not differ significantly, SSTR4 expression was increased (189.7±65.8 [normal] vs. 217.9±73.1 [cancer], p = 0.0236) and SSTR2 expression was significantly lower in prostate cancers (109.5±67.4 [normal] vs. 87.2±65.3 [cancer], p = 0.0424, Figure 3A).
