Retraction Note to: Cell Death & Disease https://doi.org/10.1038/s41419-020-2336-0, published online 24 February 2020

The Editors-in-Chief have retracted this article.

After publication, concerns were raised on images presented in this article for overlaps with itself and another retracted article [1].

Specifically:

In Fig. 2C: Panel sh-NC and circRNF20OE appear to overlap.

In Fig. 2C: Panel Vector and sh-circRNF20 appear to overlap.

Also, Image sh-circRNF20 from Fig. 2C of this article and Image NC from Fig. 2G of the retracted article [1] appear to be similar.

This and the retracted article were submitted within a close timeframe, however there are no common authors. The authors were contacted to clarify the issues but they were unable to provide the complete raw data. The Editors therefore have lost confidence in the data presented in this article.

The authors have not responded to correspondence from the Publisher about this retraction.
