Description
Summary:Objective Circulating microRNAs have been recognized as promising biomarkers for various diseases. The aim of the present study was to explore the potential role of circulating miR-107, miR-128b and miR-153 as non-invasive biomarkers in the diagnosis of ischemia stroke. Methods One hundred and fourteen ischemic stroke patients (61±11.3 years old) and 58 healthy volunteers (56±3.9 years old) matched for age and sex were enrolled in this study. Total RNA was isolated from plasma with TRIzol reagent. The circulating microRNAs levels were measured by quantitative real-time polymerase chain reaction. Results The circulating levels of miR-107, miR-128b and miR-153 significantly increased 2.78-, 2.13- and 1.83-fold in ischemia stroke patients in comparison to the healthy volunteers, respectively. Receiver operating characteristic (ROC) curves were analyzed using the SPSS software program and revealed the areas under the curve for circulating miR-107, miR-128b and miR-153 to be 0.97, 0.903 and 0.893 in ischemia stroke patients in comparison to healthy volunteers, respectively. The levels of circulating miR-107, miR-128b and miR-153 therefore positively correlated with the severity of stroke as defined by NIHSS classes. Conclusion Our results suggest that circulating miR-107, miR-128b and miR-153 might be used as potential novel non-invasive biomarkers for the diagnosis of ischemia stroke. However, future prospective trials in large-sized patient cohorts are needed before drawing any definitive conclusions.
