Figure 2. Imaging of Akt kinase inhibiton in live animals.

A, Mice transplanted with D54 cells expressing the Akt reporter were treated with vehicle control (20% DMSO in PBS), API-2 (20 mg/kg or 40 mg/kg), or Perifosine (30 mg/kg). Representative images are shown of mice prior to treatment or during maximal luciferase signal upon treatment (Max), and post-treatment. B, Tumor-specific bioluminescence activity of D54 cells stably expressing BAR in mice, treated with either the vehicle control (20% DMSO in PBS) or API-2 (20 mg/kg or 40 mg/kg), was monitored at various times. Fold induction of signal intensity over pretreatment values was plotted as mean ± SEM for each of the groups. C, Bioluminescence activity in tumor-bearing mice before and after treatment with 30 mg/kg perifosine was plotted as fold induction over pretreatment values (± SEM) for each of the groups.
