Subsequently to the publication of the above paper, the authors have realized that Figs. 3 and 4 contained errors. Two sets of bands in Figs. 3D and 4B were erroneously placed during the process of figure preparation. In Fig. 3D, the β-actin bands for the PANC-1 and CFPAC-1 cells were presented incorrectly, whereas in Fig.4B, the cdk4 bands for the CFPAC-1 cells were incorrect. The corrected versions of Figs. 3 and 4, showing the correct data for the β-actin bands in Fig. 3D and the cdk4 bands for the CFPAC-1 cells in Fig. 4B, are shown opposite.

USP22 and FoxM1 expression in fresh-frozen PDA tissues and cell lines. (A and B) RT-PCR and western blot analysis of USP22 and FoxM1 in the 26 pairs of PDA fresh-frozen tumor tissues and the paired normal carcinoma adjacent tissues. (C and D) RT-PCR and western blot analysis of USP22 and FoxM1 in the poorly differentiated PANC-1 cell line in comparison with the highly differentiated CFPAC-1 cell line.

USP22 regulates the G1/S phase transition and affects the expression of G1 phase-related proteins through FoxM1 in PDA cell lines. (A) Flow cytometry analysis was performed on the PDA cell lines PANC-1 and CFPAC-1 that were transfected by USP22, FoxM1-siRNA or USP22+FoxM1-siRNA. Values are mean ± SD for triplicate samples. (B) Cellular levels of p21, p27, cyclin D1, cdk4, cdk6 in the PDA cell lines PANC-1 and CFPAC-1 that were transfected by USP22, FoxM1-siRNA or USP22+FoxM1-siRNA. (Cand D) CCK-8 analysis was performed on the PDA cell lines PANC-1 and CFPAC-1 which were transfected by USP22, FoxM1-siRNA or USP22+FoxM1-siRNA. Values are mean ± SD for trip-licate samples. *P<0.05, compared with control. **P<0.01, compared with control.
