SLC28A1 and cancer: Many [18F]FLT transporters are upregulated in cancer, aiding efficient [18F]FLT accumulation in proliferative cells.22,23 We observed significantly increased ENT-1, ENT-2, CNT-1, and CNT-3 expression in 14-day AngII AAA than in saline control aortae (P < 0.001 for all) and in 28-day AngII AAA (P < 0.001 for all).
