Editorial Expression of Concern to: Oncogene https://doi.org/10.1038/sj.onc.1210008, published online 16 October 2006

The Editors-in-Chief would like to alert the readers that concerns have been raised regarding some of the blots presented in Fig. 4a and 5a, specifically:

  • Fig. 4a A204:Hif-1alpha and Fig. 5a A204wtp53:Hif-1alpha blots appear highly similar;

  • Fig. 4a A673:Hif-1alpha lanes 5-7 and Fig. 5a: A673:Hif-1alpha lanes 2-4 appear highly similar.

As the original raw data are no longer available due to the age of the article, in accordance with German regulations, the authors have been unable to conclusively address this issue. Readers are therefore advised to interpret these results with caution.
