Abstract

Increasing evidence has revealed that microRNAs (miRNAs) are closely associated with multiple myeloma (MM) pathogenesis and progression. Therefore, an in‑depth understanding of the biological functions of miRNAs in MM may be helpful for the identification of promising therapeutic techniques for patients with MM. miRNA‑765 (miR‑765) has been reported to be dysregulated in many types of human cancer. However, the expression pattern, specific roles and underlying mechanisms of miR‑765 in MM remain largely unknown. In the present study, plasma miR‑765 significantly increased in patients with MM and cell lines. The downregulation of miR‑765 in MM cells attenuated proliferation and promoted apoptosis. Bioinformatics analysis predicted that SRY‑Box 6 (SOX6) was a putative target of miR‑765. This was experimentally verified using a luciferase reporter assay, reverse transcription‑quantitative PCR and western blot analysis. Furthermore, plasma SOX6 was downregulated in patients with MM and the downregulation of SOX6 was inversely correlated with that of miR‑765 expression. Furthermore, SOX6 knockdown markedly abrogated the effects of miR‑765 underexpression on cell proliferation and apoptosis in MM. The current study demonstrated that miR‑765 serves an oncogenic role in MM progression by directly targeting SOX6, suggesting that miR‑765 may be a potential therapeutic target for MM prevention and treatment.
