Circulating exosomal miRNAs exerted diagnostic and prognostic value in DLBCL. (A) TEM image of exosome particles shows typical cup-shaped morphology. (B) Western blot analysis of plasma exosomes with exosomal biomarker Tsg101 and CD9. (C–E) QRT-PCR analysis of the expression levels of exosomal miR-107, miR-375-3p, and miR-485-3p in the plasma of DLBCL (n = 42) and healthy controls (n = 31). (F) Receiver operating characteristic curves of biomarkers. (G) Alluvial diagram of miR-107 expression in groups with different clinical characteristics. Red represented high expression of miR-107; blue represented low expression of miR-107. (H) Kaplan–Meier analysis of DLBCL patients from Shandong Provincial Hospital. (I) Prognosis of miRNAs in various kinds of cancers from miRNAcancerMap database. Data are mean ± s.d., n ≥ 3. *p < 0.05, **p < 0.01, and ***p < 0.001. TEM, transmission electron microscopy. ROC, receiver operating characteristics.
