The aim of this work was to study the dysfunction of miR-32 – an miRNA that was abnormally regulated in different tumors – in clinical tissues from patients with multiple myeloma (MM). The tumor tissues in which we assessed miR-32 expression levels were collected during our 5 years of clinical practice. Our study found an increase in miR-32 expression in MM tissues. Assessment of F-box and WD repeat domain-containing 7 (FBXW7) in MM tissues showed an inverse relation between the expression of FBXW7 and miR-32. To further investigate the relation between miR-32 and FBXW7, cells were transfected with miR-32 or anti-miR-32. In vitro studies found that cells transfected with miR-32 showed a lower expression of FBXW7 and a higher expression of cancer-related proteins, c-Jun and c-Myc. In contrast, the cells transfected with anti-miR32 showed a relatively higher expression of FBXW7, but a lower expression of c-Jun and c-Myc. This study may offer perceptive insights into developing new strategies for MM cancer detection and therapy.
