Figure 6. Restored VEGF-A eliminated the miR-320a induced cardiac dysfunction in doxorubicin treated mice. (A) Cardiac expression of VEGF-A detected by western blot analysis. (B) Echocardiographic detection of mice with different treatments. (C) Hemodynamic analysis measured by Millar cardiac catheter system of mice with different treatments. (D) Relative BNP expression level in heart measured by real-time PCR. (E) TUNEL staining in heart sections. (F) Expression level of CD31, CD34 and eNOS in heart detected by immunohistochemical staining. Scale bar, 200μm. Data are expressed as mean ± SEM, n≥4, *P<0.05 versus control, #P<0.05 versus Doxo + rAAV-miR-320a mut, $P<0.05 versus rAAV-miR-320a.
