Correction to “Overexpressed Hsp70 Alleviated Formaldehyde-Induced Apoptosis Partly via PI3K/Akt Signaling Pathway in Human Bronchial Epithelial Cells”

Abstract

L. Liu, Y. Huang, X. Feng, J. Chen, and Y. Duan, “Overexpressed Hsp70 Alleviated Formaldehyde-Induced Apoptosis Partly via PI3K/Akt Signaling Pathway in Human Bronchial Epithelial Cells,” Environmental Toxicology 34, no. 4 (2019): 495–504, https://doi.org/10.1002/tox.22703.

FIGURE 2The protein expression level of Hsp70 in HBE-Hsp70 and HBE-NC exposed to formaldehyde. The results were expressed as mean ± SD from three independent experiments, *p < 0.05, compared with the control group; #p < 0.05, compared with HBE-NC treated with the same concentration of formaldehyde.

FIGURE 5Effect of LY 294002 on formaldehyde-induced apoptosis in HBE-NC and HBE-Hsp70 cells. (A) Graphs obtained by flow cytometry after Annexin V-APC/7AAD dual straining. (B) Apoptosis rates were expressed as mean ± SD (n = 3), *p < 0.05, **p < 0.01, compared with the control group (0 μmol/L formaldehyde); #p < 0.05, ##p < 0.01, compared with HBE-NC + DMSO treated with the same concentration of formaldehyde; +p < 0.05, ++p < 0.01, compared with HBE-Hsp70 + LY294002 treated with the same concentration of formaldehyde.

We apologize for this error.
