SLC1A5 and neoplasm: Here, we aimed to determine whether 18F-FIMP has affinity for other tumor-related amino acid transporters, such as sodium- and chloride-dependent neutral and basic amino acid transporter B(0 +) (ATB0,+), alanine serine cysteine transporter 2 (ASCT2), and cystine/glutamate transporter (xCT).
