To the Editor:

We recently found an error in our published paper:

Singh A, Rangasamy T, Thimmulappa RK, Lee H, Osburn WO, Brigelius-Flohe R, Kensler TW, Yamamoto M, Biswal S. Glutathione peroxidase 2, the major cigarette smoke–inducible isoform of GPX in lungs, is regulated by Nrf2. Am J Respir Cell Mol Biol 2006;35:639–650.

Figure 2A was printed with an incorrect bar graph depicting GPx1 expression. The authors apologize for this error, and the correct bar graph for GPx1 expression in Figure 2A is presented here. The reviewers had seen the correct figure and the error was made during the last stages of submitting publication-quality figures.

(A) Nrf2+/+ and Nrf2–/– mice were exposed to CS for 5 h and total RNA was isolated. Expression levels of GPx1, GPx2, GPx3, and GPx4 genes were analyzed by real-time RT-PCR. GAPDH was used for normalization. Data are represented as fold change over air-exposed Nrf2–/– group.
