The expression levels of cyclophilin A (CYPA) in nasopharyngeal carcinoma serum exosomes. A, Electron microscopy identification of the extracellular vesicles of exosomes from human sera. B, Western blotting analysis of exosomal special markers (HSP70, CD63, and Tsg101) and CYPA expression in serum exosomes. C, Exosomal CYPA detection by enzyme‐linked immunosorbent assay. Data were represented as mean ± sd of three independent experiments. *P < 0.05, **P < 0.01, ***P < 0.001, as comparison to normal cases group
