Taking into account the previous reports on functional imaging of sodium iodine symporter in thyroid cancer as well as use of 18FDG PET (18Fdeoxyglucose positron tomography) imaging to trace the SLC2A1 (GLUT) level known to be upregulated in many cancers, (Penheiter et al., 2015) performed a transcriptomic analysis of in human pancreatic ductal adenocarcinoma samples obtained by laser capture microdissection. Here, SLC2A1 is linked to cancer.
