Abstract
The aim of the present study is to investigate the preventive effect of water extract of Mori Ramulus (MRWE) on oxidative stress-mediated cellular damages in rat skeletal L6 myoblasts. Our results demonstrated that MRWE pretreatment markedly improved cell survival and suppressed cell cycle arrest at the G2/M phase and apoptosis in hydrogen peroxide (H2O2)-treated L6 cells. H2O2-triggered DNA damage was also notably reduced by MRWE, which since it was correlated with protection of reactive oxygen species (ROS) production. Additionally, H2O2 stimulated cytosolic release of cytochrome c and up-regulation of Bax/Bcl-2 ratio, whereas MRWE suppressed these changes following by H2O2. Moreover, MRWE inhibited the cleavage of poly(ADP-ribose) polymerase as well as the activity of caspase-3 by H2O2. Furthermore, MRWE enhanced H2O2-mediated expression of nuclear factor erythroid 2-associated factor 2 (Nrf2) and its representative downstream enzyme, heme oxygenase-1 (HO-1). However, the protective effects of MRWE on H2O2-induced ROS production, cell cycle arrest and apoptosis were significantly attenuated by HO-1 inhibitor. In conclusion, our present results suggests that MRWE could protect L6 myoblasts from H2O2-induced cellular injury by inhibiting ROS generation along with Nrf2-mediated activation of HO-1, indicating this finding may expand the scope of application of Mori Ramulus in medicine.

Abstract
BACKGROUND Although the various pharmacological effects of Corni Fructus are highly correlated with its antioxidant activity, the blocking effect against oxidative stress in muscle cells is not clear. The purpose of this study was to investigate the effect of aqueous extracts of Corni Fructus (CFE) against oxidative stress caused by hydrogen peroxide (H2O2) in murine skeletal C2C12 myoblasts. METHODS AND RESULTS MTT assay for cell viability, DCF-DA staining for reactive oxygen species (ROS) production, Comet assay for DNA damage, annexin V-FITC and PI double staining for apoptosis, JC-1 staining and caspase assay for monitor mitochondrial integrity, and western blotting for related protein levels were conducted in H2O2 oxidative stressed C2C12 cells. Our results showed that CFE pretreatment significantly ameliorated the loss of cell viability and inhibited apoptosis in H2O2-treated C2C12 cells in a concentration-dependent manner. DNA damage induced by H2O2 was also markedly attenuated in the presence of CFE, which was associated with suppression of ROS generation. In addition, H2O2 reduced mitochondrial membrane potential and caused downregulation of Bcl-2 and upregulation of Bax expression, although these were abrogated by CFE pretreatment. Moreover, CFE blocked H2O2-induced cytosolic release of cytochrome c, activation of caspase-9 and caspase-3, and degradation of poly (ADP-ribose) polymerase. CONCLUSION Taken together, the present results demonstrate that CFE could protect C2C12 cells from H2O2-induced damage by eliminating ROS generation, thereby blocking mitochondria-mediated apoptosis pathway. These results indicate that CFE has therapeutic potential for the prevention and treatment of oxidative stress-mediated myoblast injury.

Abstract
In living cells Reactive Oxygen Species (ROS) participate in intra- and inter-cellular signaling and all cells contain specific systems that guard redox homeostasis. These systems contain both enzymes which may produce ROS such as NADPH-dependent and other oxidases or nitric oxide synthases, and ROS-neutralizing enzymes such as catalase, peroxiredoxins, thioredoxins, thioredoxin reductases, glutathione reductases, and many others. Most of the genes coding for these enzymes contain sequences targeted by micro RNAs (miRNAs), which are components of RNA-induced silencing complexes and play important roles in inhibiting translation of their targeted messenger RNAs (mRNAs). In this review we describe miRNAs that directly target and can influence enzymes responsible for scavenging of ROS and their possible role in cellular redox homeostasis. Regulation of antioxidant enzymes aims to adjust cells to survive in unstable oxidative environments; however, sometimes seemingly paradoxical phenomena appear where oxidative stress induces an increase in the levels of miRNAs which target genes which are supposed to neutralize ROS and therefore would be expected to decrease antioxidant levels. Here we show examples of such cellular behaviors and discuss the possible roles of miRNAs in redox regulatory circuits and further cell responses to stress.
