RPS3 and neoplasm: The final tumor resection and weight calculation also showed that pretreatment of exosomes derived from RPS3-overexpressing SGC7901R cells following incubation with cisplatin showed the highest tumor weight compared with cisplatin alone, while the pretreatment of exosomes derived from RPS3-silencing SGC7901R cells following incubation with cisplatin did the opposite effect (Figures 6B,C).
