[Retracted] Semaphorin 5A suppresses the proliferation and migration of lung adenocarcinoma cells

Following the publication of the above paper, it was drawn to the Editor's attention by a concerned reader that Fig. 1, showing that the downregulation of SEMA5A in lung adenocarcinoma tissues is associated with poor overall survival, was strikingly similar to a figure that had previously appeared in an article by Dan Wang and colleagues in American Journal of BioMedicine in 2014 (doi: 10.18081/2333‑5106/014‑03/292‑305). Upon receiving notification of this issue, the authors identified that Fig. 1, as shown, had been included in this paper erroneously, and requested that a corrigendum be published, featuring the correct data for Fig. 1. However, after carefully considering the matter, the Editor of International Journal of Oncology has decided that this paper should instead be retracted from the Journal on account of a lack of confidence in the presented data. The Editor apologizes to the readership for any inconvenience caused. [International Journal of Oncology 56: 165‑177, 2020; DOI: 10.3892/ijo.2019.4932].
