    • 2O). 1 h post-dose, AKT signaling was stimulated in mouse liver by hepatocyte growth factor (HGF) via tail vein injection (5 μg). Five minutes post HGF stimulation, the mice were sacrificed and livers were harvested for protein lysate preparation and quantitation by Western blot analysis of phospho-FKHRL1 (Thr32), normalized to total FKHRL1 levels.
