Background: Among B-cell lymphoma, multiple myeloma (MM) is an incurable malignancy. miR-140-3p was known to be an inhibitor in malignant tumors. However, the function of miR-140-3p in MM remains unclear. Methods: qRT-PCR was performed to determine the expressions of miR-140-3p and BZW2 mRNA. The protein level of BZW2 was determined by the western blot. Cell viability or cell apoptosis was detected by the MTT assay or flow cytometry, respectively. Binding between miR-140-3p and BZW2 was validated using the dual luciferase assay. Xenograft model...
