LNCARSR and neoplasm: Through animal fluorescence quantitative analysis, we found that the MFI of nude mouse tumors in exosome pretreatment group was significantly higher than the MFI value in no pretreatment group, while lncARSR-knockdown exosome pretreatment group had significantly reduced MFI value (Figure 8A-B), indicating, the tumor size was significantly larger in exosome pretreatment group than lncARSR-knockdown pretreatment group and no pretreatment group, suggesting that the protumor effects of exosomes are mediated through lncARSR.
