Abstract:
OBJECTIVETo investigate the diagnostic value of circulating serum miRNA for multiple myeloma.
METHODSForty blood samples from patients with multiple myeloma were collected from July 2013 to June 2014 in Department of Hematology, Zhongshan Hospital Affiliated to Xiamen University. The real-time quantitative PCR was performed to detect the serum expression levels of miRNAs (miR-29a, miR-155, miR-16 and miR-92a) circulating in the different stages of patients with multiple myeloma and evaluate the diagnostic value for patients with multiple myeloma.
RESULTSThe serum level of miR-29a significantly increased in newly diagnosed patients as compared to healthy donor (P<0.01), serum miR-155 levels were significantly lower as compared with healthy donor(P<0.001); The ratio of miR-29a and miR-155 was an effective biomarker for distinguishing multiple myeloma from healthy donor, their sensitivity and specificity were 80.8% and 83.3% respectively for myeloma diagnosis. the change of miR-29a expression was consistent with the changes of bone marrow plasma cells and M protein levels.
CONCLUSIONThese circulating serum microRNA, such as miR-29a, miR-155 and miR-16, may serve as potential diagnostic biomarkers for multiple myeloma, and the ratio of miR-29a/miR-155 may serve as a most useful biomarker for myeloma diagnosis.
