RPS3 and neoplasm: In Figure 6E, pretreatment of exosomes derived from RPS3-overexpressing SGC7901R cells following incubation with DDP showed the least apoptotic tumor cells 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.
