SLC6A3 and cancer: Our study pharmacologically indicates that Benz, GBR-12935 (a selective DAT inhibitor), and Amitriptyline (a non-selective MAT inhibitor) targeted SLC6A3/DAT, inasmuch as these drugs significantly suppressed tumorigenesis and cancer cell viability, whereas neither muscarinic antagonists, the NET inhibitor nisoxetine, the dopamine receptor antagonist sulpiride, nor dopamine did.
