OXTR and cancer: The ability of DOTA-dLVT to bind to OTR expressed in cancer cells was investigated by means of a 30 min incubation with [111In]-DOTA-dLVT, after which the presence of specific radiolabelling was observed in all three OTR-positive cell lines (MCF7, TS/A and MOG-U-V-W), but was negligible in the OTR-negative HT29 cell line.
