miR-7a/b overexpression reduced apoptosis of the heart.
(A) Representative apoptosis cells in the border zones of the hearts post MI (scale bar: 20 μm). (B) Analysis of apoptosis cells. Con: sham mice without LAD occlusion. MI: mice with LAD occlusion. (D) Days after MI. Data are the mean ± SD, n = 6–7/group, *p < 0.05 compared with Con, #p < 0.05 compared with GFP-NC.
