PRR34-AS1 regulates exosomal protein Rab27a in HCC cells. A Total exosomal protein in HepG2 cells was analyzed using RT-qPCR after PRR34-AS1 silencing. N = 3. B The level of exosome markers and extracellular vesicle-related proteins in HepG2 cell-secreted exosomes was analyzed using western blot after PRR34-AS1 silencing. N = 3. C Total exosomal protein in LM3 cells was analyzed using RT-qPCR after PRR34-AS1 silencing. N = 3. D The level of exosome markers and extracellular vesicle-related proteins in LM3 cell-secreted exosomes was analyzed using western blot after PRR34-AS1 silencing. N = 3. E Relative mRNA levels of exosomal proteins in HCC cells were analyzed using RT-qPCR after PRR34-AS1 silencing. N = 3. Data were analyzed via DGP PCR quantification. **P < 0.01, n.s. meant no significance
