Figure 7. Examination for expression of PI3K, eNOS, iNOS and p38MAPK. (A) The blotting bands and statistical analysis for PI3K, p38MAPK, eNOS and iNOS expression examined by western blot assay. **P<0.01, ***P<0.001 represent the values compared to the ND-GFP group. ##P<0.01, ###P<0.001 represent the values compared to the Ad-GFP group. ND-GFP: Non-diabetes ischemia reperfusion injury rats injected with recombined lentiviral vector expressing GFP; ND-Apelin: Non-diabetes ischemia reperfusion injury rats injected with Ad-recombined lentiviral rector expressing Apelin; Ad-GFP: Diabetes ischemia reperfusion injury rats injected with Ad-recombined lentiviral vector expressing GFP. Ad-Apelin: Diabetes ischemia reperfusion injury rats injected with Ad-recombined lentiviral rector expressing Apelin.
