In the field of nuclear medicine molecular imaging, the targeted SPECT and PET imaging of pancreatic cancer is often based on the specific biomarkers expressed in cancer cells (e.g. integrin αvβ6, tissue factor, neurotensin receptor 1) or neo-vascularendothelial cells (e.g. integrin αvβ3), but few researches focus on the CAFs or PSCs 8,14-16. The gene discussed is NTSR1; the disease is cancer.
