The authors have retracted this article. After publication, the authors found a duplicated image in Fig. 2e, which was addressed by a Correction [1]. However, further concerns were raised regarding highly similar images in Fig. 5 h (antagomiR-NC, right) and 6n (siRNA-NC, right).

The authors have thoroughly checked the original data, and determined that there were oversights during data collection. Therefore, they have decided to retract the article to avoid misleading the readers.

Lang Chen, Tao Yu, Hang Xue, Faqi Cao, Dong Chen, Bobin Mi and Guohui Liu agree to this retraction. Yuan Xiong, Chenchen Yan, Wu Zhou, Yun Sun and Yiqiang Hu have not responded to any correspondence from the Publisher about this retraction.
