PARP-1 protein levels in mitochondrial and nuclear fractions of myoblasts and myotubes.

<p>Western blot analysis detected elevated expression of PARP-1 in myoblasts than in myotubes for both nuclear (A) and mitochondrial (B) fractions. Densitometric analysis of PARP-1 protein level in myoblast was set as 100%. Statistical analyses of n = 3 independent experiments were assessed; where ** indicates <i>p</i><0.001.
