miR-24 modulates ER-mediated apoptosis pathway.

<p>(A) miR-24 attenuates thapsigargin and tunicamycin induced cell death through ER-mediated apoptosis pathway. Mouse cardiomyocytes with or without overexpression of miR-24 were cultured with thapsigargin or tunicamycin for six hours. Cells were stained with FITC-conjugated Annexin V and PI for flow cytometry. Tha, thapsigargin; Tun, tunicamycin. (B) Percentage of AnnexinV⁺PI^– cells in Fig. 2A shown as mean ± SEM. These data are representative of three independent experiments. *, p<0.05. Data were analyzed by unpaired Student's t test. (C) Western blot for Caspase 12 and Bim from primary CMs transfected with miR-24 mimic, inhibitor, or corresponding controls. GAPDH serves as a loading control.
