Figure 4. Effect of E. coli infection on the protein levels of PPARα, SREBP-1c and p-AMPK/AMPK in liver of the lean and DIO mice by Western blotting. (A) PPARα, (B) SREBP-1c, (C) p-AMPK/AMPK. Values are displayed as mean ± SD (n=6). “*”p<0.05 compared with the control (0 d or pre-infection) within the time of infection; “#”p<0.05 between the lean and DIO mice at the same time point of infection.
