This article has been retracted due to the agreement between the authors and the journal Editor-in-Chief, Torgny Stigbrand. The retraction has been agreed due to the fact that the authors found that the primers that were used for STIM1 were wrong. They actually amplified several other genes as well. When the authors used a new STIM1-specific primer pairs that passed blast control, they could not reproduce the published data. As result, the data does not support the essential conclusion of the authors that risperidone may promote differentiation of glioma stem-like cells through the Wnt signaling pathway. The authors accept full responsibility of this mistake and deeply apologize to the scientific community for the inconvenience.
