The Editor-in-Chief has retracted this article. After publication, concerns were raised regarding overlapping images in Figs. 2i and 5k, as well as high similarity between Fig. 8e Ki-67 lenti-sh-PVT1-3 and Fig. 4c Ki67 Score 2 + in an earlier article [1], which the authors addressed by a Correction [2]. However, further similarities were subsequently identified between Figs. 1c Score 2 + and 3 + and 8e HK2 lenti-sh-PVT1-3 and lenti-sh-NC, respectively. In addition, the publisher has found a number of highly similar images and repetitive patterns in the raw data provided by the authors for Figs. 2i and 5k.

The Editor-in-Chief therefore no longer has confidence in the presented data.

Ranran Sun agrees with this retraction. None of the other authors have responded to any correspondence from the editor or publisher about this retraction.
