Lack of nutrients and growth factors activates FoxO transcription factors in pancreatic beta-cells, whereas PI3K/Akt-dependent inactivation of FoxO favors proliferation. To address the link between FoxO and cell cycle control, we deprived Min6 cells of serum and glucose which activated FoxO and inhibited proliferation. Concomitantly, expression of the transcriptional repressor Bcl-6 was stimulated, whereas cyclin D2 was lowered. Gain of function approaches indicated that FoxO activation was… CONTINUE READING
