In line with our ex-vivo results, Fournier et al.—evaluating two BBN-based radiopharmaceuticals for the identification of breast and prostate cancers in Balb/c and tumor-bearing Balb/c nude mice—showed elevated accumulation of both 64Cu and 68Ga/NOTA-PEG-[D-Tyr6,βAla11,Thi13,Nle14]BBN(6-14) [68Ga/NOTA-PEG-BBN(6-14)] in the pancreas and adrenal glands abounding in GRPR [39,40]. The gene discussed is GRPR; the disease is prostate carcinoma.
