RESUMEN
Following the publication of this paper, it was drawn to the Editors' attention by a concerned reader that the western blotting data shown in Fig. 4B and the Transwell cell invasion data shown in Figs. 2D and 4E were strikingly similar to data appearing in different form in other articles written by different authors at different research institutes that had already been published elsewhere prior to the submission of this paper to Molecular Medicine Reports (one of which has been retracted). Moreover, there appeared to be inappropriately edited western blot bands featured in Figs. 4 and 5. In view of the fact that certain of the abovementioned data had already apparently been published previously, the Editor of Molecular Medicine Reports has decided that this paper should be retracted from the Journal. After having been in contact with the authors, they agreed with the decision to retract the paper. The Editor apologizes to the readership for any inconvenience caused.

RESUMEN
MicroRNA (miR)6715p serves as a tumor suppressor in several types of cancer, including gastric and breast cancer. However, the function of miR6715p in nonsmall cell lung cancer (NSCLC) has not been described in detail. The present study aimed to investigate the role of miR6715p in NSCLC. The expression levels of miR6715p were determined in NSCLC tissue samples and cell lines using reverse transcriptionquantitative PCR. Prediction of miR6715p targets was performed using the TargetScan database and verified by luciferase reporter assay and western blot analysis. Functional experiments, including Cell Counting Kit8, wound healing and Transwell assays, were performed in NSCLC cells. The results of the present study demonstrated that lower expression levels of miR6715p were observed in NSCLC tissues and cell lines compared with those in the corresponding controls. Low miR6715p levels were significantly associated with an advanced TumorNodeMetastasis stage and lymph node metastasis in patients with NSCLC. Microfibrilassociated protein 3like (MFAP3L) was confirmed to be a direct target of miR6715p. The proliferative, migratory and invasive abilities of NSCLC cells were suppressed following transfection with miR6715p mimics and promoted by the miR6715p inhibitor compared with those in the respective control groups. In addition, the effects of miR6715p on cell proliferation, migration and invasion, as well as the expression levels of proliferating cell nuclear antigen, Ecadherin, Ncadherin and vimentin were reversed by MFAP3L overexpression. In conclusion, targeting the miR6715p/MFAP3L signaling pathway may be a promising therapeutic strategy for NSCLC treatment.
