Figure 4From: Antioxidant polyphenol-rich extracts from the medicinal plants Antirhea borbonica, Doratoxylon apetalum and Gouania mauritiana protect 3T3-L1 preadipocytes against H2O2, TNFα and LPS inflammatory mediators by regulating the expression of superoxide dismutase and NF-κB genes Effect of polyphenol-rich plant extracts on preadipocyte mitochondrial metabolic activity. Cells were exposed to each plant extract (0–200 μM GAE) for 24, 48 and 72 h. Then, the mitochondrial metabolic activity of cells was measured by MTT assay. Data are means ± SEM of three independent experiments.Back to article page
