Fig 5. (A) In unperturbed conditions HER2-dependent activation of AKT inhibits the cyclin E/CDK2 inhibitor p27. (B) Inhibition of HER2 suppresses AKT activity leading to increased levels of p27 and inhibition of the cyclin E/Cdk2 activity. (C) Trastuzumab-resistant cells harboring an amplification of cyclin E renders these cells insensitive to the negative regulation by p27.
