title: RETRACTED: ATPase inhibitory factor 1 is a prognostic marker and contributes to proliferation and invasion of human gastric cancer cells.
abstract: This article has been retracted: please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy).
  
  This article has been retracted at the request of the authors, who have informed the Editor-in-Chief that the regulatory effect of IF1 on apoptosis reported in the paper cannot be repeated. In subsequent experiments, two independent shRNAs designed to knockdown IF1 were unable to induce apoptosis in SGC-7901 or MGC-803 cells. The authors cannot explain why the results are not reproducible, but speculate that the original findings may reflect an off-target effect of IF1 shRNA knockdown. The authors no longer have confidence in the reliability of the results and would like to apologize for any inconvenience caused. The Editor-in-Chief agreed to retract the article.
