SGLT2 Na+/glucose cotransporters are expressed in human pancreatic and prostate adenocarcinomas as judged by in vitro Me4FDG uptake assays and immunocytochemistry and by mouse in vivo models as shown by Me4FDG micro-PET, ex-vivo autoradiography, and immunocytochemistry. Here, SLC5A2 is linked to prostate adenocarcinoma.
