Retraction Note: Decreased microRNA-452 expression and its prognostic significance in human osteosarcoma.

The Editor-in-Chief is retracting this article [1] due to overlap with previously published articles [2, 3]. Fig. 3D "miR-452 mimics" is very similar to Fig. 3D "si-BANCR" in article [2]. Fig. 3D "miRNC" is very similar to Fig. 3E "si-NC" in article [2] and to Fig. 3E "miR-224 mimics" in article [3].
