From the Editor:
Following an investigation by the staff of the American Thoracic Society as well as the University of Louisville, and at the request of the authors, the American Journal of Respiratory Cell and Molecular Biology has agreed to retract the following articles due to concerns related to digital manipulations and image duplications that were performed by the first (also corresponding) author without the knowledge of the coauthors, bringing into question the validity of the findings: ShouWei Han, Hilda N. Rivera, and Jesse Roman (2005) “Peroxisome proliferator–activated receptor-γ ligands inhibit α5 integrin gene transcription in non–small cell lung carcinoma cells” (1); and ShouWei Han, Jeffrey D. Ritzenthaler, XiaoJuan Sun, Ying Zheng, and Jesse Roman (2009) “Activation of peroxisome proliferator–activated receptor β/δ induces lung cancer growth via peroxisome proliferator–activated receptor coactivator γ-1α” (2).
The first author has not responded to requests by coauthors. Therefore, the coauthors have requested retraction of these articles and apologize to the readers of the journal.
