The authors have retracted this article  because they have been unable to replicate the results of their study. After publication they expanded the sample size and repeated the measurements, and found that miR-29b-3p was not always down-regulated in the rat MCAO model and OGD cell model. In addition, when the processing time was doubled, miR-29b-3p showed an upward trend. The conclusions presented are therefore not reliable. All authors agree with this retraction.
