This Article contains an error in Figure 8, where the image for the PM2.5 + CEOs (day 7) group in panel 8C was mistakenly duplicated and partially overlapped with that of the PM2.5 + CEOs (day 3) group.

The corrected Figure 8 is published below.

CEOs suppressed PM2.5-induced calmodulin disorder. RYR2 and SERCA2a mRNA levels were assayed by real-time RT-PCR using the 2−ΔCt method. RYR2 protein level was detected by WB and IHC. CEOs reduced the level of RYR2 (BE) and increased the expression of SERCA2a (A). Data are expressed as mean ± standard error of the mean (n = 3–5, **P < 0.01, *P < 0.05 versus the PM2.5 + saline group I).
