Role of Exosomes and Microvesicles in Multiple MyelomaFriday, 19 September 2014 at 11:30 Add to Calendar ▼2014-09-19 11:30:002014-09-19 12:30:00Europe/LondonRole of Exosomes and Microvesicles in Multiple MyelomaExosomes and Single Cell Analysis Summit in San Diego, California, USASan Diego, California, USASELECTBIOenquiries@selectbiosciences.com Multiple myeloma (MM) is a hematological malignancy of plasma cells in the bone marrow (BM). The microenvironment of the BM plays a key role in MM cell persistence and survival through release of soluble factors and expression of adhesion molecules. The role of extracellular vesicles, exosomes and microvesicles, in this model of MM, has not been readily explored. We were the first one to characterize the protein content and relative abundance of vesicles derived from distinct MM cell lines. We established differences in protein abundances between MM patient’s serum and bone marrow derived vesicles when compared to healthy donor extracellular vesicles. During my talk I will show that serum CD44 is primarily localized to the peripheral vesicles of MM patients and that extracellular vesicles associated CD44(EV-CD44) positively correlates with serum ß2 microglobulin levels, serum creatinine and ISS stage suggesting EV-CD44 can function as a biomarker of MM. These results generate a foundation for hypothesis driven studies of MM biology and the potential use of serum CD44 as a novel serum biomarker of MM. |
