Mammalian target of rapamycin complex 1 (mTORC1) is activated by amino acids to promote cell growth via protein synthesis. Specifically, Ras-related guanosine triphosphatases (Rag GTPases) are activated by amino acids, and then translocate mTORC1 to the surface of late endosomes and lysosomes. Ras homolog enriched in brain (Rheb) resides on this surface and(More)
Activation of KISS1 receptor (KISS1R or GPR54) by its ligands (Kisspeptins) regulates a diverse function both in normal physiology and pathophysiology. In cancer, KISS1R has been implicated in tumor angiogenesis and metastasis, but a broader evaluation of KISS1R in tumorigenesis and tumor progression is yet to be conducted. In this study, we used mouse(More)
KiSS1 and its cognate G-protein-coupled receptor, GPR54, have diverse functions. While KiSS1 and GPR54 have been intensively studied in physiology, their role in cancer is still unclear. In cancer, KiSS1 and GPR54 have been known to suppress metastasis by inhibiting cancer cell motility. However, recent studies suggest that KiSS1 and GPR54 have varied roles(More)
