Targeting Glutamine Transporters as a Novel Drug Therapy for Synovial Sarcoma.

ABSTRACT: Background/Objectives: Synovial sarcoma (SS) is a malignant soft tissue neoplasm with good outcomes in adolescents with localized tumors, but poor outcomes in older adults and in advanced or metastatic cases. Targeting cancer metabolism, such as glutamine metabolism, is a promising therapeutic strategy. In this study, we investigated glutamine dependency in SS and assessed the therapeutic potential of inhibiting the glutamine transporter ASCT2 using V9302. Methods: Immunohistochemistry (IHC) was used to evaluate ASCT2 expression in SS and liposarcoma (LPS) specimen. The effects of glutamine deprivation and V9302 were examined in a SS cell line (HS-SY-II), patient-derived SS cells (SSH1), and a normal cell line (HEK293). Cell viability, apoptosis, and protein expression
