Metabolomic Analysis of the Ameliorative Effect of Enhanced Proline Metabolism on Hypoxia-Induced Injury in Cardiomyocytes
Figure 2
Enhanced proline metabolism induced by the overexpression of PRODH reduces apoptosis levels, whereas PRODH knockdown has the opposite effect. (a) Representative images and analysis of FITC-Annexin V/PI-positive apoptotic H9c2 cells by flow cytometry (). (b) Relative LDH release (). (c) Cardiomyocyte apoptosis was evaluated by TUNEL, and the percentage of TUNEL-positive cells is shown. Scale bar, 100 μm (). (d) Representative images and quantitative analysis of cleaved caspase-3 expression in H9c2 cells (). The data are presented as the values. versus the normoxia control group; # versus the Ad-NC or Ad-shNC negative control group.
