Antioxidant Activity of Valeriana fauriei Protects against Dexamethasone-Induced Muscle Atrophy

Figure 2

Antioxidant activity and cytotoxicity of VF extract on C2C12 myoblasts. Antioxidant assays were performed with VF extract at concentrations from 0.5 to 10 mg/mL. (a) DPPH inhibition (%) by VF. (b) ABTS inhibition (%) by VF. (c) Viability (%) of C2C12 cells was measured by MTT assay after 24 h of VF treatment. (d, e) The effect of VF on transcriptional activity of ERRγ and PPARδ. (f) Representative images of oxidized DCF-DA in C2C12 myoblasts treated with DEX or/and VF. (g) Fluorescence intensity depicting ROS production measured by DCF fluorescence in C2C12 cells. The data are presented as the . Statistical significance was determined by one-way ANOVA. , versus the nontreated group.
