Abstrakt: This chapter describes methods for studying downstream events of the PI3K/Akt signaling cascade, focusing on the FoxO transcription factors. These approaches also represent alternative means for gauging the phosphoinositide-3 kinase/Akt activity. We describe protocols for the fractionation of cytoplasmic and nuclear protein extracts and for studying transcription factor DNA-binding activity in vitro and in vivo.
