Long acting somatostatin-14 (SST) analogs are used clinically to inhibit tumor growth and proliferation of various tumor types via binding to specific receptors (R). We have developed a 111In-/90Y-labeled SST analog, DOTA-(D)betaNal1-lanreotide (DOTALAN), for tumor diagnosis and therapy. 111In-/90Y-DOTALAN bound with high affinity (dissociation constant,(More)
Recent data suggest that somatostatin receptors (SSTRs) are expressed on various tumor cells. High-level expression of SSTR on the tumor cell surface provides the basis for the successful clinical use of radiolabeled ligands for the in vivo localization of tumor sites. We have characterized the in vitro binding properties of the novel SSTR ligand 99mTc-P829(More)
A variety of tumor cells have been shown to express lipoprotein receptors. Recent data suggest that lipoprotein receptors may play a regulatory role in the growth of certain tumor cells. We investigated the effects of vasoactive intestinal peptide (VIP) and somatostatin-14 (SST-14) on the binding of 111Indium-labeled lipoproteins [(111)In-low density(More)
