DIABLO and Duchenne muscular dystrophy: Finally, co-staining of iPSC-CMs with mitochondria dye MitoTracker (red) and DIABLO (green) revealed the retention of DIABLO in mitochondria from control iPSC-CMs, whereas the release of DIABLO from mitochondria into cytosol was observed in DMD iPSC-CMs (Fig. 4D, supplementary material Fig. S5).
