ABSTRACT
OBJECTIVE@#To investigate the clinical correlation of expression level changes of miR-181b and miR-194 to the pathogenesis of acute graft-versus-host disease (aGVHD), and determine plasma miR-181b and miR-194 as the potential biomarkers for aGVHD.@*METHODS@#The plasma samples were collected from 31 patients who underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT) at before HSCT, 15 days after HSCT and onset of aGVHD. The expression levels of miR-181b and miR-194 were detected by quantitative real-time PCR. Receiver-operating characteristic (ROC) curves and the area under the ROC curve (AUC) were used to assess the sensitivity and specificity of miRNA biomarkers for the diagnosis of aGVHD.@*RESULTS@#MiR-181b and miR-194 downregulated after treatment were significantly upregulated in the plasma at onset of aGVHD (P0.05). The expressions of plasma miR-181b and miR-194 collected on day 15 after HSCT were significantly upregulated in the patients with aGVHD in comparison with non-GVHD patients (P<0.05). Moreover, these elevated miRNAs were detected before aGVHD. The AUC of miR-181b predicting aGVHD was 0.91±0.05 (specificity was 0.94, sensitivity was 0.69). The AUC of miR-194 predicting aGVHD was 0.91±0.06 (specificity was 0.94, sensitivity was 0.77).@*CONCLUSION@#MiR-181b and miR-194 may serve as early biomarkers for the diagnosis and prognosis of aGVHD.
