| 36466784 | Graphene Oxide Enhances Biogenesis and Release of Exosomes in Human Ovarian Cancer Cells. | We observed that graphene oxide (GO), cisplatin (CIS), and C6-Ceramide (C6-Cer) stimulated acetylcholine esterase and neutral sphingomyelinase activity, total exosome protein concentration, and exosome counts associated with increased level of apoptosis, oxidative stress and endoplasmic reticulum stress. |
| 36527848 | Exosomal microRNAs regulate the heat stress response in sea cucumber Apostichopus japonicus. | We made the initial report of exosomes from sea cucumber Apostichopus japonicus, that were classically cup-shaped and had an average size of 74.65 nm, and identified specific exosome biomarkers (HSP70, TSG101, and CD9). |
| 36576666 | Effect of platelet exosomes loaded with doxorubicin as a targeted therapy on triple-negative breast cancer cells. | In exosome characterization, CD62 positivity was higher in platelet pellets, while CD9 positivity was higher in released exosomes. |
| 36585155 | CD9-positive Exosomes Derived from Cancer-associated Fibroblasts Might Inhibit the Proliferation of Malignant Melanoma Cells. | CAF-derived exosomes were positive for CD9 and CD63 and remarkably inhibited the proliferative capacity of A375 and MMAc cells. The expression of CD9, CD63, and CD81 in CAF-derived exosomes was examined using western blotting. |

| 36640525 | A peptide binding to the tetraspanin CD9 reduces cancer metastasis. | The anti-cancer metastasis effect of CD9-BP was evidenced by the in vitro inhibition of cancer cell migration and invasion as well as exosome secretion and uptake, which are essential processes during metastasis. |
| 36688929 | Biogenesis of JC polyomavirus associated extracellular vesicles. | These findings point to a role for exosomes and secretory autophagosomes in the biogenesis of JCPyV associated EVs with specific roles for nSMase2, CD9, CD81, RAB8A, RAB27A, and GRASP65 proteins. |
