| Outline of Final Research Achievements |
Expression of sigma-2 receptor is seen in many kinds of solid tumor cell, such as breast cancer and the pancreatic cancer, and sigma-2 receptor of up to 10 times overexpressed in the proliferation period. In other words, sigma-2 receptor was important biomarker of the solid tumor cell for the proliferation period, and sigma-2 receptor imaging is estimated to possess the possibility for early detection and the increase ability diagnosis of cancer. [125I]PIDV, which I developed in this study, showed superior sigma-2 receptor accumulation in in vitro and in vivo and [123I]PIDV worked successfully in sigma-2 receptor imaging with tumor-bearing mouse (human breast adenocarcinoma cell line MCF-7) by the SPECT.
