Abstract

Purpose: To determine the effect of miR-379 in multiple myeloma.

Methods: Quantitative reverse transcription-polymerase chain reaction (qRT-PCR) was used to evaluate the expression of miR-379 in multiple myeloma cells. The effect of miR-379 on multiple myeloma progression was investigated by cell counting, bromodeoxyuridine staining, flow cytometry and Western blot analysis. A potential target for miR-379 was determined using a luciferase reporter assay.

Results: MiR-379 expression was reduced in multiple myeloma cells, while over-expression of miR-379 increased both cell viability and proliferation of these cells (p < 0.05). Moreover, miR-379 blocked cell cycle multiple myeloma cells and promoted apoptosis by decreasing Bcl-2 expression, and increasing the expression of cleaved caspase-3 and Bax. MiR-379 bound to Y-box binding protein 1 (YBX1) and reduced YBX1 mRNA and protein expression in multiple myeloma cells (p < 0.05).

Conclusion: A YBX1-mediated tumor-suppressive role for miR-379 in multiple myeloma cells has been identified, suggesting a potential strategy for the treatment of multiple myeloma.
