[Retracted] MicroRNA‑766 inhibits papillary thyroid cancer progression by directly targeting insulin receptor substrate 2 and regulating the PI3K/Akt pathway.

Following the publication of this paper, it was drawn to the Editors' attention by a concerned reader that various panels showing the data from flow cytometry experiments in Figs. 2D, 4D and 5D, and certain of the tumor images featured in Fig. 7A, were strikingly similar to data appearing in different form in other articles by different authors. Furthermore, overlapping data panels were identified within this paper comparing the cell migration assay images between Figs. 2C and 4F. Owing to the fact that the contentious data in the above article had already been published elsewhere, or were already under consideration for publication, prior to its submission to , the Editor has decided that this paper should be retracted from the Journal. The authors were asked for an explanation to account for these concerns, but the Editorial Office did not receive a reply. The Editor apologizes to the readership for any inconvenience caused.
