After the publication of this article [1], concerns were raised with results presented in Fig 4. Specifically,
In addition to the issues listed above, concerns were raised about the validity of primers used in the RT-PRC experiment.
The authors did not respond to the journal’s communications, and the concerns remain unresolved.
The unresolved concerns call into question the reliability and validity of the published results, and the article’s adherence to the journal’s editorial policies in place at the time the article was submitted. In light of these unresolved concerns, the PLOS One Editors retract this article.
