An investigation at the University of Maryland, Baltimore, based on allegations by the corresponding author, has determined that data fabrication and manipulation had occurred in this study, specifically in relation to results described in Figures 2 and 4 and summarized in Figure 8. Additionally, efforts by members of the Munger laboratory not involved in this study to replicate key aspects of these experiments, as well as those described in Figures 3 and 7, were unsuccessful. The authors have thus lost confidence in the results presented in Figures 2, 3, 4, and 7 and summarized in Figure 8. Therefore, this article is being retracted by the American Physiological Society at the request of all the authors.
