Abstract: Objective To explore the relationship between the differentiation of L6 myoblasts and oxidative stress. Methods MTT assay was used to determine the viability of L6 myoblasts, from which the total RNA was extracted for amplification of the myogenin gene fragment by RT-PCR. H2O2-induced morphological changes of the cells were observed. Results The myoblasts treated with low concentration of reactive oxygen (50 μmol/L H2O2) for 1 h exhibited accelerated cell growth (P<0.05), and treatment with 50 and 150 μmol/L H2O2 induced the gene expression of myogenin, a molecular marker for differentiation of myoblasts. Morphological study revealed myotube formation and accelerated differentiation of the myoblasts induced by H2O2. Conclusion The reactive oxygen may serve as the intracellular signal molecules to induce the growth and differentiation of the myoblasts.
