          Abstract

          This article has been retracted by Hindawi following an investigation undertaken by the publisher [1]. This investigation has uncovered evidence of one or more of the following indicators of systematic manipulation of the publication process: Discrepancies in scope Discrepancies in the description of the research reported Discrepancies between the availability of data and the research described Inappropriate citations Incoherent, meaningless and/or irrelevant content included in the article Peer-review manipulation The presence of these indicators undermines our confidence in the integrity of the article's content and we cannot, therefore, vouch for its reliability. Please note that this notice is intended solely to alert readers that the content of this article is unreliable. We have not investigated whether authors were aware of or involved in the systematic manipulation of the publication process. In addition, our investigation has also shown that one or more of the following human-subject reporting requirements has not been met in this article: ethical approval by an Institutional Review Board (IRB) committee or equivalent, patient/participant consent to participate, and/or agreement to publish patient/participant details (where relevant). Wiley and Hindawi regrets that the usual quality checks did not identify these issues before publication and have since put additional measures in place to safeguard research integrity. We wish to credit our own Research Integrity and Research Publishing teams and anonymous and named external researchers and research integrity experts for contributing to this investigation. The corresponding author, as the representative of all authors, has been given the opportunity to register their agreement or disagreement to this retraction. We have kept a record of any response received.

          Role of MiR-27a-3p in Intervertebral Disc Degeneration through Targeting RASSF5 via MST1/LATS1 and RAS/RAC1 Signaling Pathway

          Background The apoptosis of nucleus pulposus (NP) cells reduces the number of nucleus pulposus cells in intervertebral disc tissue, resulting in intervertebral disc degeneration (IDD). MicroRNAs (miRNAs) play an important regulatory role in abnormal cell proliferation and apoptosis. Methods The miR-27a-3p expressions in degenerative NP tissue and cells were measured via qPCR. The impacts of miR-27a-3p on the proliferation and apoptosis of human NP cells were evaluated by flow cytometry assays, MTT assays, and western blot analyses. In addition, target scan and luciferase reporter assay were applied to confirm that RASSF5 was directly binding to miR-27a-3p. Western blot was applied to assess the relationship between miR-27a-3p, RASSF5 and MST1/LATS1, and RAS/RAC1 signaling pathway. Results MiR-27a-3p was downregulated in degenerative NP tissues and cells by comparison with the control group. MiR-27a-3p overexpression enhanced cell proliferation and suppressed apoptosis of NP cells, while the above factors showed an opposite tendency after in the miR-27a-3p inhibitor group. The western blot experiment similarly suggested mir-27a-3p apparently downregulated apoptosis-related proteins (Bax and caspase-3) and upregulated antiapoptotic proteins (Bcl-2). In addition, RASSF5 was confirmed to be directly regulated by miR-27a-3p using the luciferase reporter assay. Overexpressed RASSF5 could reverse the effects caused by miR-27a-3p mimic. Finally, miR-27a-3p could downregulate RASSF5 and affected the MST1/LATS1 and RAS/RAC1 pathway. Conclusion MiR-27a-3p may target RASSF5 and enhance cell proliferation and imped cell apoptosis of the nucleus pulposus cells via the MST1/LATS1 and RAS/RAC1 pathway, lessening the degeneration of intervertebral discs.
