The Editor has retracted this article. After publication, concerns were raised regarding possible image similarities within the article. Further investigations by the Publisher detected additional potential image similarities and irregularities. Specifically:
Figure 3 A, lanes 2, 5 and 7 appear to be highly similar to one another.
Figure 3 A, lanes 21 and 23 appear to be highly similar to one another.
Figure 3D, pancreas CA (lane 6) and CUP (lane 12) appear to be highly similar to one another.
Figure 3B, sample 58 and Fig. 3C, HCC, sample 1,11,14 and 17 appear to show unusual western blot band features which appear to differ from the rest of the bands in Fig. 3.
The authors were unable to provide sufficient response to the concerns raised. Due to this, the Editor no longer has confidence in the presented data.
Frank Tacke, Nicolas Kanig and Peter R Mertens agree with this retraction.
Thilo Kaehne and Christian Trautwein did not respond to correspondence from the Publisher about this retraction.
The Authors Abdelaziz En-Nia, Christiane S Eberhardt and Victoria Shpacovitch could not be contacted by the Publisher.
