Introduction. microRNAs (miRNAs) are small noncoding RNAs and functional regulators of the immune system. They are reported to be involved in the set of diverse pathways associated with chronic allograft dysfunction (CAD), a foremost cause of renal graft loss. In this study, the researchers sought to evaluate the significance of circulating miR-150, a vital regulator in differentiation and activation of immune cells, in anticipating the renal graft function. Methods. The plasma miRNA levels of 53 renal transplant recipients: 27 with stable graft function (SGF) and 26 recipients with biopsy proven interstitial fibrosis and tubular atrophy (IFTA) were evaluated using real-time quantitative-PCR (q-PCR) .Results. Increased expression levels of miR-150 (P< 0.001), was detected in IFTA group in comparison to SGF group, this level was even higher in sever IFTA grade (P< 0.001) patients. Receiver operating characteristic (ROC) analysis showed that circulating miR-150 with 100% sensitivity and 80% specificity could discriminate IFTA from SGF group (area under the curve [AUC]= 0.963, 95% confidence interval [CI]= 00.825 to 0.999, P< 0.001). Conclusion. Increased level of miR-150 may indicate active immune response and extra cell matrix accumulation and could discriminate all IFTA patients from normal individuals and; therefore, can be used for monitoring patients besides other validated miRNAs. |
