Correction: The heme oxygenase 1 inducer (CoPP) protects human cardiac stem cells against apoptosis through activation of the extracellular signal-related kinase (ERK)/NRF2 signaling pathway and cytokine release. [Additions and Corrections] (Journal of Biological Chemistry)

VOLUME 287 (2012) PAGES 33720-33732The wrong tubulin immunoblot was used in Fig. 1E. The wrong FACS plot image was used in the lower right panel of Fig. 5C. The wrong t-ERK and tubulin immunoblots were used in Fig. 7C. In supplemental Fig. S2B, the wrong tubulin immunoblot was used. Additionally, the wrong number (n = 4) of independent experiments was used for the FACS analyses shown in Figs. 2, B and C, 3, C and D, 4, C and D, and 5, C and D. The FACS analyses for cell apoptosis assays were performed at the same time for hCSCs expressing scramble shRNA (Fig. 2, B and C), HO-1 shRNA (Fig. 3, C and D), NRF2 shRNA (Fig. 4, C and D), or COX-2 shRNA (Fig. 5, C and D). For all groups of cells, there were 8 independent experiments except hCSCs expressing scramble shRNA with CoPP preconditioning but not subjected to oxidative stress, for which there were 7 independent experiments (due to insufficient cell numbers). These 8 or 7 original data sets were reanalyzed and corrected with the new quantitative data. Representative images for the FACS plots were selected from 1 of the 8 experiments. These errors have now been corrected and do not affect the results or conclusions of this work.jbc;294/12/4725/F1F1F1Figure 1E.jbc;294/12/4725/F2F2F2Figure 2, B and C.jbc;294/12/4725/F3F3F3Figure 3, C and D.jbc;294/12/4725/F4F4F4Figure 4, C and D.jbc;294/12/4725/F5F5F5Figure 5, C and D.jbc;294/12/4725/F7F6F7Figure 7C.jbc;294/12/4725/FS2F7FS2Figure S2B.
