Abstract | OBJECTIVE: MATERIALS AND METHODS: RESULTS: Depletion of FBXL5 enhances cisplatin resistance of gastric cancer cells through Erk and p38 activation. However, FBXL5 did not affect the abundance and stability of RhoGDI2. Instead, FBXL5 was rapidly degraded in response to cisplatin treatment in RhoGDI2-overexpressing gastric cancer cells. CONCLUSIONS: Collectively, our data suggested the existence of a FBXL5-RhoGDI2 negative feedback loop in RhoGDI2-induced cisplatin resistance in gastric cancer cells, implicating FBXL5 as a novel and promising therapeutic target for RhoGDI2-induced cisplatin resistance gastric cancers.
