doi: 10.1089/ars.2018.7521

Figure Lengend Snippet: Effect of ISV on PA-induced mitochondrial dysfunction and oxidative stress. Rat primary hepatocytes were treated with PA (1 mM) and different concentrations of ISV (0, 1, 3, and 10 μM) for 24 h. (A) The MTP was measured by JC-1 staining followed by flow cytometry. Representative flow cytometry diagrams of three independent experiments are shown. (B) The mitochondrial mass was measured by using MitoTracker Green FM. The relative amount of each treatment group to control group was calculated. (C) Representative immunoblot images of cytosolic cytochrome c, β-actin, and Cox4i1 are shown. (D) ROS levels were measured by flow cytometry to detect intracellular fluorescence intensity of DCF. (E) Relative amounts of 4-HNE, SOD, and MDA were measured as described in the Materials and Methods section. (F) Representative immunoblot images of p66Shc in cytosol and mitochondria. Cox4i1 and Actin were used as loading control of mitochondrial and cytosolic protein, respectively. JC-1 aggregates and high DCF intensity cells ratios were calculated, respectively, based on the mean ± SEM of three independent experiments. Relative protein levels of Cytochrome c and p66Shc were calculated based on the mean ± SD of three independent experiments. Statistical significance compared with control or PA group, *p < 0.05, **p < 0.01, ***p < 0.001, and NS, no significance.

Rat primary hepatocytes were transduced with lentiviral p66Shc shRNAs for 48 h as described in the Materials and Methods section. (A) Representative immunoblots of p66Shc and β-actin are shown.
