Popis: Multiple myeloma (MM) is a disease with an adverse outcome and new therapeutic strategies are required to combat this disease. It is well known that tumor‑suppressor microRNA (miRNA) acts as a new potential anticancer agent. Accumulating evidence showed that microRNA-145 (miR-145) is a candidate tumor suppressor miRNA. However, whether miR-145 is involved in the development and progression of MM reamins to be determined. In the present study, we investigated the therapeutic potential of synthetic miR-145 against human MM cells in vitro and in vivo. The results showed that miR-145 was reduced in MM tissues and cell lines. Enforced expression of miR-145 by transfection with miR-145 mimics inhibited cell proliferation, migration, and the invasion abilities of H929 cells. Furthermore, our results demonstrated that the enforced expression of miR-145 in H929 cells profoundly decreased the levels of p-AKT and p-PI3K, which may contribute to some extent to the inhibition of MM cell proliferation and survival. The enforced expression of miR-145 in a xenograft mouse model suppressed tumor growth. In conclusion, our findings suggested that miR-145 may act as a tumor suppressor and contributes to the progression of MM. Additionally, miR-145 mimics is a potential therapeutic agent for the treatment of MM.
