In the original article, there were mistakes in Figure 1, Figure 3, Figure 4 and Figure 5 as published. The mistakes are in Figure 1A-right (GAPDH), Figure 3H-right (GAPDH), Figure 4G (BE2 cells: 48h for Ctrl siRNA + Etoposide) and Figure 5G (AS cells: 0h and 48h for ATXN3 siRNA#2), as these images were misused. The corrected Figure 1, Figure 3, Figure 4 and Figure 5 appear below.

Figure 1 Downregulation of ATXN3 promoted perifosine-induced cell death in NB cells. AS cells were treated with different concentrations of perifosine (2.5, 5, 7.5, and 10 μM) for 24 h, or transfected with ATXN3 siRNA (#1, #2, #3, and control) for 48 h, or transfected with ATXN3 siRNA (#1, #2, and #3) for 16 h followed by 24 h treatment of perifosine. (A) The expression of ATXN3 were detected by Western blot; (B, C) AS cells were transfected with ATXN3 siRNAs (#1, #2), and BE2 cells were transfected with ATXN3 siRNA2 (marked as ATXN3 siRNA) for 16 h, followed by 48 h treatment of perifosine: Cell confluence was dynamically detected by IncuCyte Zoom and analyzed at the end of experiment; (D, E) Cell survival was detected by CCK8 assay; (F, G) cell apoptosis was detected by Annexin V/PI flow cytometry; (H) The images of AS and BE2 cells with ATXN3 siRNAs transfection and perifosine treatment at 0 h and 48 h were recorded. Bar, SD, **P < 0.01, ATXN3 siRNAs + perifosine vs. control siRNA + perifosine; ***P < 0.001, ATXN3 siRNA #2 + perfosine vs. control siRNA + perifosine.

Figure 3 BIM mediated the cell death induced by a combination of MK-2206 treatment and ATXN3 downregulation in NB cells. AS cells were transfected with ATXN3 siRNAs (#1 and #2) and BE2 cells were transfected with ATXN3 siRNA #2 (marked as ATXN3 siRNA) for 16 h followed by 48 h treatment of MK-2206. (A, B) Cell confluence was dynamically detected by IncuCyte Zoom and analyzed at the end of experiment; (C, D) Cell survival was detected by CCK8 assay; (E, F) Cell apoptosis was detected by Annexin V/PI flow cytometry. Bar, SD, **, P< 0.01, ***, P<0.001, ATXN3 siRNAs + perifosine vs. control siRNA + perifosine; (G) The images of AS and BE2 cells with ATXN3 siRNAs transfection and perifosine treatment at 0 and 48 h were recorded; (H) AS and BE2 cells were transfected with ATXN3 siRNA2 (marked as ATXN3 siRNA) for 16 h, and treated with MK-2206 for 24 h, the expression of ATXN3 and BIM was detected by Western blot; (I) BIM siRNA #1 (marked as BIM siRNA) and ATXN3 siRNA #2 (marked as ATXN3 siRNA) were transfected into AS and BE2 cells alone or combination, then the cells were treated with MK-2206 for 48 h, cell survival was detected by CCK8 assay; (J, K) Cell confluence was detected by IncuCyte Zoom. Bar, SD, **, P<0.01, ATXN3 siRNA + MK-2206 + BIM siRNA vs. ATXN3 siRNA + MK-2206.

FIGURE 4

Figure 4 Downregulation of ATXN3 decreased the sensitivity of NB cells to etoposide. AS cells were transfected with ATXN3 siRNAs (#1, #2) and BE2 cells were transfected with ATXN3 siRNA #2 (marked as ATXN3 siRNA) for 16 h, followed by 48 h treatment of etoposide. (A, B) Cell confluence was dynamically detected and analyzed by IncuCyte Zoom; (C, D) Cell survival was detected by CCK8 assay; (E, F) Cell apoptosis was detected by Annexin V/PI flow cytometry; (G) The images of AS and BE2 cells with ATXN3 siRNAs transfection and etoposide treatment at 0 h and 48 h were recorded. Bar, SD, ***, P<0.001, **, P<0.01, ATXN3 siRNAs + etoposide vs. control siRNA + etoposide.

FIGURE 5
www.frontiersin.org

Figure 5 Downregulation of ATXN3 decreased the sensitivity of NB cells to cisplatin. AS cells were transfected with ATXN3 siRNAs (#1, #2) and BE2 cells were transfected with ATXN3 siRNA #2 (marked as ATXN3 siRNA) for 16 h, followed by 48 h treatment of cisplatin. (A, B) Cell confluence was dynamically detected and analyzed by IncuCyte Zoom; (C, D) Cell survival was detected by CCK8 assay; (E, F) Cell apoptosis was detected by Annexin V/PI flow cytometry; (G) The images of AS and BE2 cells with ATXN3 siRNAs transfection and cisplatin treatment at 0 h and 48 h were recorded. Bar, SD, ***, P<0.01, **, P<0.01, ATXN3 siRNAs + cisplatin vs. control siRNA + cisplatin.
