RPS3 and neoplasm: The results showed that pretreatment of exosomes derived from RPS3-overexpressing SGC7901R cells following incubation with DDP showed the highest expression levels of p-cofilin-1 in the xenograft tumor compared with DDP alone, while the pretreatment of exosomes derived from RPS3-silencing SGC7901R cells following incubation with DDP did the opposite effect (Figure 6G).
