Correction to “Winter Polycyclic Aromatic Hydrocarbon-Bound Particulate Matter from Peri-urban North China Promotes Lung Cancer Cell Metastasis”

Abstract

We recently found that the incorrect representative images were used in Figure 3. The error affects only the presentation of representative images and not the underlying calculations. None of the conclusions of the work is affected. The wound healing assay of 0.3 μg/mL PM₁₀ at 24 h and 10 μg/mL PM_2.5 and PM₁₀ at 24 h in Figure 3A and the transwell image panels of the 3 and 10 μg/mL PM_2.5 groups in Figure 3B have been corrected in the version of Figure 3 presented here. Figure 3. Effects of winter PM on A549 cell migration and invasion. (A) Effect of winter PM on A549 cell migration determined by a wound healing assay (200× magnification). A549 cells were treated with winter PM at various concentrations (0, 0.1, 0.3, 1, 3, and 10 μg/mL) for different times (0, 6, 12, and 24 h), and the micrographs show representative images of cell migration. (B) Effect of winter PM on A549 cell invasion as detected by the cell invasion assay (400× magnification). A549 cells were incubated with winter PM at various concentrations (0, 0.1, 0.3, 1, 3, and 10 μg/mL) for 24 h; subsequently, the invasive ability was evaluated using the cell invasion assay. The top section includes micrographs of the representative images of cell migration under different treatment conditions, and the bottom panel shows the calculation of the mean number of invasive cells in each group. For PM_2.5, *p < 0.05 and **p < 0.01 vs the control group; for PM₁₀, ^#p < 0.05 vs the control group. This article has not yet been cited by other publications.
