The Editor-in-Chief has retracted this article [1]. A report (https://ori.hhs.gov/content/case-summary-yakkanti-sudhakar) by the US Office of Research Integrity has concluded that the image shown as the protein band tumstatin (α3(IV)NC1) in Fig. 2 (lanes 2–4) was also used in [2] to represent a different experiment. The Editor-in-Chief therefore no longer has confidence in the conclusions presented in this article. Akulapalli Sudhakar does not agree with this retraction. The Editor-in-Chief was not able to obtain a current email address for Chandra S Boosani.
