The Editor-in-Chief has retracted this article after concerns were raised about the data reported. Specifically, in Fig. 14, the panel for kidney T1 appears to overlap with the panel for kidney T3, and the panel for colon C1 appears to overlap with the panel for colon T3. The Editor-in-Chief no longer has confidence in the findings or conclusions of this article. Syed Ahmad Shah and Muhammad Sohail disagree with this retraction. The remaining authors did not respond to correspondence from the publisher about this retraction.
