From: Essential role of PH domain and leucine-rich repeat protein phosphatase 2 in Nrf2 suppression via modulation of Akt/GSK3β/Fyn kinase axis during oxidative hepatocellular toxicity

Figure 2

Fyn kinase inhibition subdues endogenous oxidative load and enhances cellular antioxidant defense. Hepatocytes were treated with varying concentrations of PP1 (5–25 μM) for 30 min. (a) Alteration in enzyme activities of TrxRed, GR, GPx, GST and NQO1 in PP1-stressed hepatocytes. (b) Sub-cellular GSH levels assessed using fluorescence microscopy of CMFDA-stained hepatocytes treated with 15 μM and 25 μM PP1 for 30 min; (magnification × 63). ROS generation was assessed by (c) FACS analysis of DCF stained cells and (d) fluorimetric estimation of Ethidium/DHE fluorecence ratio. (e) Alteration of mitochondrial membrane potential assessed by JC-1 staining of PP1-treated hepatocytes (magnification × 40). The micrographs represent images obtained after merging of red and green fluorescence channels. The data are presented as mean±S.E. of at least three independent experiments. *P<0.05 compared with control
