Pro-BDNF Contributes to Hypoxia/Reoxygenation Injury in Myocardial Microvascular Endothelial Cells: Roles of Receptors p75NTR and Sortilin and Activation of JNK and Caspase 3
Figure 3
Effects of the anti-pro-BDNF antibody on apoptosis, migration, and capillary-like-structure formation among MMECs after exposure to HG and H/R. (a) Effects of pro-BDNF on apoptosis were analyzed by flow cytometry of MMECs after different treatments: control, H/R, H/R + anti-pro-BDNF, and H/R + vehicle. (b, c) The functional effects of pro-BDNF on MMECs were assessed by capillary-like-structure formation and cell scratch assays. (d) Relative apoptosis levels and fold changes are expressed in relation to the control group. The H/R group showed markedly increased relative apoptosis levels, decreased capillary-like-structure formation, and reduced cell migration when compared with the control group. These effects were reversed by treatment with the anti-pro-BDNF antibody to the levels similar to those in the control group. The data were subjected to one-way ANOVA. The error bars represent SEM. as compared with the control group; as compared with the H/R group or the H/R + vehicle group.
