Abstract

Multiple myeloma (MM) is a cytogenetically heterogeneous malignancy of plasma cells in bone marrow. Among the cytogenetic abnormalities of MM, del(17p) is a well‑recognized high‑risk genetic lesion associated with the late stage and progression of the disease. MicroRNA (miR)‑324‑5p, located at 17p13.1, was identified to be involved in the dysregulation of a number of types of malignant disease. However, whether miR‑324‑5p is associated with the development and progression of MM remains unknown. In the present study, the expression status of miR‑324‑5p in MM, and its effect on the migratory and invasive ability of MM cells were investigated. Using ubiquitination pathway polymerase chain reaction array, the inhibitory effect of miR‑324‑5p on the ubiquitinated proteins was investigated. It was identified that miR‑324‑5p levels were decreased in samples from patients with MM and MM cell lines. Increased expression of miR‑324‑5p by transfection of miR‑324‑5p mimic suppressed the proliferative, migratory and invasive abilities of MM.1R cells. Furthermore, increased expression of miR‑324‑5p in MM.1R cells inhibited the ubiquitination pathway and decreased the levels of ubiquitination‑associated proteins, particularly the Skp1‑Cullin1‑F‑box β‑transducin repeat‑containing protein (SCFβ‑TrCP) E3 ligase. In addition, the results of the present study demonstrated that the SCFβ‑TrCP E3 ligase may contribute to the suppression of MM cell motility by inhibiting the expression of metastasis‑associated genes, including metastasis suppressor 1. In conclusion, the results of the present study suggested that miR‑324‑5p may act as a tumor suppressor by impairing the motility of MM cells by suppressing the ubiquitination pathway.
