| TRPC5 | CirExo-TRPC5 might act as a noninvasive chemoresistance marker and might serve as an adjuvant to the current imaging examination-based chemoresistance | ultracentrifugation | Immunofluorescence confocal laser scanning microscope | 131 breast cancer female patients (case) | Anthracycline/taxane-based chemotherapy | 28032400 | ||
| Del-1 | As the current prospective cohort study demonstrated a normalization of exosomal Del-1 after curative surgery, exosomal Del-1 can be confirmed as a potent diagnostic biomarker for breast cancer. Plus, a high Del-1 level after surgery seems related with early relapse suggesting a potential prognostic marker by identifying the existence of residual tumor | ultracentrifugation | transmission electron microscopy | 114 breast cancer patients (case) | diagnosis | Link | ||
| CD47 | A differential CD47 expression in blood-derived individual circulating exosomes that is correlated with breast cancer status, demonstrating a great potential of individual exosome profiles in biomarker discovery | MDA-MB-231,MCF-12A | ultracentrifugation | electron microscopy | 50 breast cancer samples (case) 40 healthy samples (control) | diagnosis | 27819324 | |
| GSTP1 | Affecting drug metabolism---Anthracycline/taxane-based neoadjuvant chemotherapy | MCF7 | ultracentrifugation | transmission electron microscopy | drug resistance | 28438694 | ||
| ABCB1 | Exosomes are effective in transferring drug resistance as well as P-gp from drug-resistant breast cancer cells to sensitive ones. The delivery of P-gp via exosomes may be a mechanism of exosome-mediated drug resistance transfer | MCF7 | ultracentrifugation | electron microscopy | drug resistance | 25077924 | ||
| hsa-miR-1246 | Hsa-miR-1246 promotes cell proliferation,invasion and drug resistance by targeting CCNG2 in breast cancer | MDA-MB-231 | ultracentrifugation | scanning electron and confocal microscopy | metastasis | 29216623 | ||
| UCHL1 | UCH-L1-containing exosomes can transfer chemoresistance to recipient cells and these exosomes may be useful as non-invasive diagnostic biomarkers for detection of chemoresitance in breast cancer patients, achieving more effective and individualized chemotherapy | MCF7 | ultracentrifugation | transmission electron microscopy | chemotherapy | 28334432 | ||
| CD24 | We suggest that CD24 could be an additional marker for the enrichment of tumor-derived exosomes from blood | AllPrep DNA/RNA Mini Kit (Qiagen,Hilden,Germany) centrifugation | electron microscopy | 8 breast cancer samples (case) 6 Lung cancer patients (control) | 21601258 | |||
| hsa-miR-130a | Comparing the miRNAs in MDA-Exo to MCF-Exo showed a higher expression of tumorigenic mir-130a in MDA-Exo. it has been shown that mir-130a contribute to tumorigenesis of colon cancer by regulating TGB-β/Smad signaling | MCF7,MDA-MB231 | ultracentrifugation | electron microscopy | 24468161 | |||
| hsa-miR-195 | Preliminary data indicated that detection of cancer-specific miRNA (miR-103, miR-191, miR-195) in exosomes associated with the fraction of red blood cells allowed to discriminate HFs and BCPs more precisely compared to cell-free exosomes circulating in plasma | centrifugation | transmission electron microscopy | 10 patients (case) 10 healthy donors (control) | 30868953 |
