Fig. 4 — AnnexinV-FITC/PI double staining flow cytometry to detect the apoptosis rate. The apoptosis rates of H9C2 cells were increased by hypoxia and reoxygenation (H+R). These changes were antagonized by Sfrp1-transfected cells before hypoxia and reoxygenation (Sfrp1+H+R). The Wnt signaling pathway activator, Licl, reduced the effects of Sfrp1. a Control group. b H+R group. c Sfrp1+H+R group. d Sfrp1+H+R+Licl group. e Median values with interquartile range (box) and range (whiskers). Post-hoc analyses of group differences were assessed with Kruskal-Wallis pairwise comparison. Statistical significance was set at the standard level (p<0.05), and the Bonferroni correction was applied in post-hoc analyses (α=0.05/6=0.0083). (Note:* vs. control P<0.001; # vs. H+R P<0.001; vs. Sfrp1+H+R P<0.001) (Additional files 1, 2, 3 and 4)
