We wish to retract our research article entitled “Retinoic acid- incorporated glycol chitosan nanoparticles inhibit Ezh2 expression in U118 and U138 human glioma cells” published in Molecular Medicine Reports 12: 6642–6648, 2015. An interested reader noted some anomalies in the presentation of Fig. 4 in our paper, calling into question the validity of the reported data. In examining our original article, we acknowledge that the data for RA (25 µm) did not show a higher density of cells compared with RA (10 µm), as shown in Fig. 4, and therefore Fig. 4 conveyed inaccurate information for the readers. Owing to the importance of these results, which bear significantly upon the conclusions that one may draw from this work, we have decided to withdraw our paper from Molecular Medicine Reports.
