A Corrigendum on
Doxycycline Inhibits Cancer Stem Cell-Like Properties via PAR1/FAK/PI3K/AKT Pathway in Pancreatic Cancer
By: Liu H, Tao H, Wang H, Yang Y, Yang R, Dai X, Ding X, Wu H, Chen S and Sun T (2021) Front. Oncol. 10:619317. doi 10.3389/fonc.2020.619317
In the original article, there was a mistake in Figures 2 and 5 as published. The presented figure of siPAR1 (0 h) in Figure 2A and the presented figure of Group 30 μM (cells treated with 30 μM of doxycycline) in Figure 5E were wrongly presented in the original article. Furthermore, the annotation in the ordinate axis of the statistical figure in Figures 2B and 5E should be “invasion cells per field” not the “passed cells per field.” The corrected Figures 2 and 5 appear below.
FIGURE 2
Figure 2 PAR1 promotes EMT progression of pancreatic cancer cells. (A) Effect of PAR1 on Panc-1 and Aspc-1 cell migration potential detected using the wound healing assay. (B) Effect of PAR1 on pancreatic cancer cell invasion potential by using matrigel coated transwell assay. (C) Effect of PAR1 on the E-Cad and VIM expression detected by Western blot analysis. (D) Effect of PAR1 on the E-Cad and VIM expression detected by immunofluorescence. Data are shown as the mean ± SD (*P < 0.05, **P < 0.01).
FIGURE 5
Figure 5 Doxycycline inhibits the cancer stem cell-like properties of pancreatic cancer cells. (A) Effect of doxycycline on PAR1 activation stimulated by thrombin in pancreatic cancer cells detected by the Ca2+-mobilization assay. (B) Effect of doxycycline on pancreatic cancer cell viability after 48, 72, and 96 h treatment. (C) Effect of doxycycline on pancreatic cancer stem cell marker CD133 in Panc-1 cells. (D) Effect of doxycycline on the mammosphere formation of Panc-1 cells. (E) Effect of doxycycline on pancreatic cancer cell invasion ability. (F) Effect of doxycycline on pancreatic cancer cells migration ability. (G) Limiting dilution assay of pancreatic cancer stem cell from Panc-1 cells after treatment with doxycycline in node mice (n = 8). Cancer stem cell frequency was determined by ELDA. Data are shown as the mean ± SD (*P < 0.05, **P < 0.01).
