G3BP1 and neoplasm: To determine whether G3BP1 knockdown impacts RCC tumor growth and metastasis in vivo, we performed the orthotopic tumor xenografts with implantation of luciferase-labeled G3BP1 knockdown cells (ACHN-shG3BP1-luciferase) and control RCC cells (ACHN-Scr-luciferase) into the sub-renal capsule of adult nude mice left kidney.
