[Retracted] Upregulation of microRNA‑27b contributes to the migration and invasion of gastric cancer cells via the inhibition of sprouty2‑mediated ERK signaling.

Following the publication of this paper, it was drawn to the Editors' attention by a concerned reader that the Transwell cell migration assay data shown in Fig. 4C were strikingly similar to data appearing in different form in other articles by different authors. 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.
