A, representative Western blots of phosphorylated AMPK (Thr-172) and total AMPK in homogenates of mice placenta from control and fADN group at E18.5. B, the expression levels of phosphorylated AMPK (Thr-172) and total AMPK from control (C, n= 9) and fADN (A, n= 7) infused group are shown in the bar graph. After normalization to β-actin, the mean density of control samples was assigned an arbitrary value of 1. Individual C and A density values were expressed relative to this mean. Values are given as means + SEM. *P < 0.05 versus control; Student's unpaired t test.
