We found that the EV miR155 levels were significantly higher in chronic lymphocytic leukemia (CLL), acute myeloid leukemia (AML) and Waldenström's macroglobulinemia (WM) cases compared to controls.
Among deregulated miRNAs, miRNA-155 has been shown to play a pivotal role in the biological characteristics of this disease both in vitro and in vivo, thus providing the rationale for testing miRNA-based therapeutic approaches for the treatment of WM.
We found that microRNA-155 regulates proliferation and growth of WM cells in vitro and in vivo, by inhibiting MAPK/ERK, PI3/AKT, and NF-kappaB pathways.
