The Editor-in-Chief has retracted this article at the authors' request. After publication, concerns were raised regarding the figures published in this article. Specifically:

  • In Fig. 5b, the blue signal in the DAPI and MERGED columns do not appear to match.

  • In Fig. 6, the Control plot appears to be missing some data points; the HA-PCL-CAP % values don't appear to match the data point distribution.

  • In Fig. 9, the Normal and CAP group images appear to originate from the same sample with different magnification.

  • The western blots in Fig. 11a contained splice marks and highly similar bands. This was addressed by a correction [1]. However, the blots in the correction don't match the data presented in the bar graphs for Bax and casp-9.

Additionally, the study does not appear to adhere to the journal's animal ethics requirements. The authors have not commented on any of these concerns. The Editor-in-Chief therefore no longer has confidence in the presented data.

None of the authors have responded to any correspondence from the editor or publisher about this retraction.
