Abstract:
:Glutamine catabolism is considered to be an important metabolic pathway for cancer cells. Glutaminase (GLS) is the important rate-limiting enzyme of glutamine catabolism. miR-137 functions as a tumor suppressor in many human malignant tumors. However, the role and molecular mechanism of miR-137 and GLS in malignant melanoma has not been reported. In this study, we showed that miR-137 was decreased in melanoma tissue, and the low miR-137 level and high GLS expression are independent risk factor in melanoma. miR-137 suppressed the proliferation and glutamine catabolism of melanoma cells. GLS is crucial for glutamine catabolism and growth of malignant melanoma. We also demonstrated that miR-137 acts as a tumor suppressor in melanoma by targeting GLS. This result elucidates a new mechanism for miR-137 in melanoma development and provides a survival indicator and potential therapeutic target for melanoma patients.
