The effects of tobacco polysaccharides fractions on exosomal miRNAs expression levels and interaction between miRNA and mRNA. a The expression levels of HepG2 cell exosome miR-155-3p were detected by RT-qPCR; b The expression levels of HepG2 cell exosome miR-17-3p were detected by RT-qPCR; c The relative fluorescence values after transfection and mutation, which suggested that significant interaction existed between miR-155-3p and target gene PPAR-α; d The relative fluorescence values after transfection and mutation, which suggested that significant interaction existed between miR-17-3p and target gene CYP7A1; e The possible interaction sites for miR-155-3p and target gene PPARα were predicted; f The possible interaction sites for miR-17-3p and target gene CYP7A1 were predicted
