AGT and triple-A syndrome: Paproski et al. characterized [18F]FLT transport by these transporters in cancer cells and demonstrated that they—particularly ENT-1 in murine tumor models—facilitate [18F]FLT uptake.22,23 Consistent with increased 14-day AngII AAA [18F]FLT uptake on in vivo PET/CT and ex vivo gamma counting, these transporters were significantly upregulated in 14-day AngII AAA tissues.
