Mitochondria morphology shown by confocal microscopy in L6 myoblast incubated with Dex for 0, six, and 24h and quantification of mitochondrial volume and number per cell (A). Western blot analysis of DNM1L, MFN2, mtHSp70, and GApDH in Dex treated L6 myotubes for 0, 6, and 24 h (B). Histamine induced Ca2+ release in manage and Dex-treated L6 myotubes (C). Histamine induced Ca2+ uptake by mitochondria in control and Dex incubated L6 myotubes (D). Information: mean SeM of at least three independent experiments. Statistically important variations had been calculated employing ANoVA in combination using a tukey test for group comparison. *P 0.05 vs. manage.Cell CycleVolume 13 Issue014 Landes Bioscience.
