Notch1 signaling inhibits LDH release and reduces infarct size in isolated rat hearts. A, LDH release in each group. B, infarct size in each group. C, TTC staining of cardiac slices in each group. Data were presented as mean±SD, n=6. Mock1 indicated the hearts infected with empty vector, Mock2 indicated the hearts infected with vector containing nonspecfic sequences. ▲P>0.05, *P<0.05, **P<0.01.
