doi: 10.1038/s41420-023-01636-2
Figure Lengend Snippet: Three days post hepatic I/R, the mice were randomized and injected with the control AAV8 or AAV8-PGC-1α. Their liver tissues were harvested at 4 weeks post hepatic I/R. A H&E, Immunohistochemistry staining of Flag, α-SMA and Sirius red staining. Scale bars: 50 μm. B Western blot analyses of Flag, PGC-1α, IL-6, JAK2, STAT3, Ym-1, Fizz1, CCR2, collagen I and α-SMA expression, # P < 0.05 vs. the Sham-NC, * P < 0.05 vs. the I/R-NC. C RT-qPCR analyses of IL-6, STAT3, Ym-1, Arg-1, collagen I and α-SMA to GAPDH mRNA transcripts. * P < 0.05, ** P < 0.01. D The levels of serum ALT, * P < 0.05. Data are representative images or shown as mean ± SD of each group (6–8/group) from at least three separate experiments.
