Figure Lengend Snippet: Fig. 7. Blockade of leptin-induced NADPH oxidase pathway reduces the productions of 4-HNE, DLK1, β-catenin, and Sox9, accompanied with the increase in PPARγ expression, in HSCs in ob/ob mouse model of TAA-induced liver injury. Two groups of mice (6 mice/each group) were, respectively, received DPI (1 μg/g body weight, once per day) or vehicle throughout the 4- week period of TAA (200 μg/g body weight, two times a week) plus leptin (1 μg/g body weight, once per day) treatment (Two groups: T + L + DPI; T + L + V). Double fluorescence staining on liver section was performed for detecting positive HSCs for 4-HNE, DLK1, β-catenin, Sox9, PPARγ, and synaptophysin (SYP) by using the respective primary antibody and the respective secondary antibody as described in Fig. 6. The nuclei were counterstained with Hoechst 33342 (blue fluorescence). The representative images were captured with the fluorescence microscope. Scale bar 25 μm. Arrowheads indicated examples of positively stained cells. The total HSCs (SYP-positive HSCs) and 4-HNE-, DLK1-, β-catenin-, Sox9-, PPARγ- positive HSCs were counted in six randomly chosen fields at 100-fold magnification. The value was expressed as fold change relative to the respective total HSCs (empty column) and was shown as a histogram on the respective right panel. ⁎P b 0.05.
Article Snippet: Briefly, after blocked with normal serum, the liver sections were incubated with primary antibody against p47phox (1:100, Cat. SC-14015, Santa Cruz, CA, USA), DLK1(1:50, Cat. SC-25437, Santa Cruz, CA, USA), Sox9 (1:50, Cat. SC-20095, Santa Cruz, CA, USA), β-catenin (1:100, Cat. SC-7199, Santa Cruz, CA, USA), 4-HNE (1:50, Cat. Ab46546, Abcam, Cambrige, MA, USA), PPARγ (1:100, Cat. 19481, Abcam, Cambrige, MA, USA) and primary antibody against synaptophysin (SYP, 1:10, Cat. SC365488, Santa Cruz, CA, USA), a marker for quiescent and activated HSCs [23], followed by incubationwith DyLight594-conjugated secondary antibody (1:500, Cat. GtxRb-003-D5948NHSX, ImmunoReagents, Inc., Raleigh, USA) and DyLight488-conjugated secondary antibody (1:500, Cat. GtxMu-003-D488NHSX, ImmunoReagents, Inc., Raleigh, USA).
