Abstract
Objective: Multiple myeloma (MM) is a plasma cell malignancy characterized by abnormal plasma cell proliferation in the bone marrow. Circulating exosomal miRNA-451 is associated with the progression of many tumors, but the relationship between its expression and MM has not been reported. In this study, we aimed to investigate the clinical value of miRNA-451 as a biomarker for diagnosis and prognosis of multiple myeloma.
Methods: A total of 120 patients with multiple myeloma and 120 healthy control people were recruited in this study. The miRNA-451 expression in serum exosomes of participants was measured by quantitative real-time polymerase chain reaction, and the diagnostic value of miRNA-451 for multiple myeloma was assessed by receiver operating characteristic (ROC) curve. The correlation between miRNA-451 expression and plasma cells ratio and M protein content was analyzed by Pearson correlation coefficient. The prognosis of different miRNA-451 expression was evaluated by survival curves.
Results: Results suggested that serum exosomal miRNA-451 expression was significantly decreased in patients with multiple myeloma rather than in the healthy controls. The ROC curve showed that area under the curve value of miRNA-451 was 0.888, suggesting that miRNA-451 had diagnostic value to multiple myeloma. Moreover, there was a negative correlation between miRNA-451 expression and plasma cells ratio or M protein content. Survival curves showed that patients with high miRNA-451 expression had a longer survival time, suggesting the value of miRNA-451 as a prognostic indicator of multiple myeloma.
Conclusion: We demonstrated the relationship between miRNA-451 expression and multiple myeloma, indicating that miRNA-451 in circulating exosomes may be an effective diagnostic biomarker and prognostic indicator for multiple myeloma.
