Considering SLC7A3's role as an arginine transporter and its connection to tumorigenesis [20-22], The substantial functional overlap among SLC transporters and the complexity of their interplay in response to environmental stresses remain poorly elucidated, which poses challenges in understanding the specific roles and therapeutic potential of SLC7A3 in breast cancer [23]. The gene discussed is SLC7A3; the disease is breast carcinoma.
