Notch1 signaling is activated in H9c2 cells exposed to IPC and IPost. A, N1ICD level was upregulated in IPC and IPost. B, Hes1 level was regulated by H/R, IPC and IPost with or without LV-N1ICD/LV-N1ICD-shRNA infection. Data were presented as mean±SD, n=3. Mock1 indicated cells infected with empty vector, Mock2 indicated cells infected with vector containing nonspecfic sequences. ▲P>0.05, *P<0.05, **P<0.01.
