Influence of Nitric Oxide generated through microwave plasma on L6 skeletal muscle cell myogenesis via oxidative signaling pathways
Abstract Myogenic precursors are myoblasts that have a potency to differentiate into muscle fibers on injury and maintain the regenerative power of skeletal muscle. However, the roles of exogenous nitric oxide (NO) in muscle development and myoblast differentiation are largely unknown. Therefore, in...

| Sumario: | Abstract Myogenic precursors are myoblasts that have a potency to differentiate into muscle fibers on injury and maintain the regenerative power of skeletal muscle. However, the roles of exogenous nitric oxide (NO) in muscle development and myoblast differentiation are largely unknown. Therefore, in this study, we examined the effects of exogenous NO generated by a microwave plasma torch on rat myoblastic L6 cell proliferation and differentiation. We observed that the differentiation of L6 myogenic precursor cells into myotubes was significantly enhanced after NO treatment. The expression of the myogenesis marker proteins and mRNA level, such as myoD, myogenin, and myosin heavy chain (MHC), as well as the cyclic guanosine monophosphate (cGMP) level, were significantly increased after the NO treatment, without creating toxicity. Moreover, we observed that the oxidative stress signaling [extracellular-signal-regulated kinase (Erks), and Adenosine monophosphate-activated protein kinase (AMPK)] phosphorylation was higher in NO treated cells than in the control cells [without NO treatment]. Therefore, these results reveal the exogenous NO role in regulating myoblast differentiation through the oxidative stress signaling pathway. Through this work, we can suggest that exogenous NO can help in cell differentiation and tissue regeneration, which provides new possibilities for plasma medicine. |
