In the published article, there was an error in Figure 4 and Figure 5 as published. The representative images and quantified data in Figures 4B, C and Figures 5G, H have been presented incorrectly. Two pictures were taken from the same cell culture well with HG treatment in Figure 4B and HG + OGD + nmFGF1+A-769662 treatment in Figure 5G, respectively. Therefore, we reassembled and quantified all pictures in Figures 4B, C and Figures 5G, H. The corrected Figure 4 and Figure 5 and its captions appear below.
Figure 4. NmFGF1 reversed the reduction of tube formation and cell migration in HG + OGD-treated HBMEC cells. (A) The effect of nmFGF1 on the viability of HG + OGD-treated HBMEC cells. (B) The effects of nmFGF1 on tube formation, original magnification: ×40. (C) Quantitative analysis of the number of capillary-like tubes. (D) Wounding healing migration assay of HBMEC cells; images show wound areas as observed by phase-contrast microscopy, original magnification: ×40. (E) The migration ratio was calculated using Image Pro Plus software (n = 3). Date are presented as means ± SEM. #p < 0.05, ##p < 0.01, ###p < 0.001 vs. NG group; &p < 0.05 vs. HG group; *p < 0.05, **p < 0.01, ***p < 0.001 vs. HG + OGD group.
Figure 5. NmFGF1 promoted tube formation and migration of HBMEC in HG + OGD-treated HBMEC cells by activating the AMPK signaling pathway. (A) Western blotting analysis of p-AMPK and AMPK levels in a mouse model of diabetic stroke treated with or without nmFGF1. β-actin was used as a loading control. (B) The ratio of p-AMPK/AMPK. (C) The levels of p-AMPK and AMPK in HBMEC cells, as determined by western blotting. (D) The ratio of p-AMPK/AMPK in HBMECs, as quantified by image software. (E) Cells treated with AMPK agonist or inhibitor. AMPK agonist, A-769662, 10 nM; AMPK inhibitor, compound C, 5 μM. Tube formation was observed by phase contrast microscopy, original magnification: ×40. (F) The number of tubes formed in HBMECs treated with AMPK agonist or inhibitor. (G) The migration ability of HG + OGD-cultured HBMECs treated with an AMPK agonist or inhibitor. Images of the wound areas were observed by phase-contrast microscopy. A-769662, 10 nM, compound C, 5 μM; Original magnification: ×40. (H) The migration ratio was calculated using Image Pro Plus software. (I) AMPK expression was silenced by the transfection of siRNA. (J) The effect of AMPK silencing on tube formation. Original magnification: ×40. (K) Quantitative analysis of tube formation. (L) Wounding healing migration assay of cells in which AMPK had been silenced by siRNA. Original magnification: ×40. (M) Quantitative analysis of migration ratio (n = 3). Data are presented as means ± SEM. #p < 0.05, ##p < 0.01, ###p < 0.001 vs NG group; *p < 0.05, **p < 0.01, ***p < 0.001 vs HG + OGD or HG + PT group; ^p < 0.05, ^^p < 0.01, ^^^p < 0.001 vs HG + OGD + nmFGF1 group.
