(a) The predicted circPTGR1–miRNA–mRNA interaction network, generated by Cytoscape. (b) circPTGR1 mRNA expression level in exosomes isolated from serum obtained from the in vivo metastasis model mice (hsa_circ_0088030: NC exo vs. PBS, P = .0102; sh exo vs. NC exo, P = .0043; hsa_circ_0003731: sh exo vs. NC exo, P = .0142; hsa_circ_0008043: NC exo vs. PBS, P = .0193; sh exo vs. NC exo, P = .0240). (c, d) MET expression levels in tissues from the in vivo metastasis model mice. (For miR449: NC exo vs. PBS, P = .0108; sh exo vs. NC exo, P = .0003. For MET: NC exo vs. PBS, P = .0230; sh exo vs. NC exo, P = .0163.) Scale bars: 100 μm. * P < .05 vs. PBS treatment. #P < .05 or ## P < .01 vs. NC group. (e) MET protein level in tissues from the in vivo metastasis model mice.
