Figure 6. Restored VEGF‐A eliminated the miR‐320a induced cardiac dysfunction in doxorubicin treated mice. (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.
