Background
The Forkhead family of transcription factors is involved in tumorigenesis of rhabdomyosarcoma and acute leukemias Within the family, three members (FoxO1, FoxO4, and FoxO3a) have sequence similarity to the nematode orthologue DAF-16, which mediates signaling via a pathway involving IGFR1, PI3K, and Akt Active forkhead members act as tumor suppressors by promoting cell cycle arrest and apoptosis. Increased expression of any FoxO member results in the activation of the cell cycle inhibitor p27 Kip1. Forkhead transcription factors also play a part in TGF-β-mediated upregulation of p21 Cip1, a process negatively regulated through PI3K Increased proliferation results when forkhead transcription factors are inactivated through phosphorylation by Akt at Thr24, Ser256, and Ser319, which results in nuclear export and inhibition of transcription factor activity Forkhead transcription factors can also be inhibited by the deacetylase sirtuin (SirT1)AMPK phosphorylates FoxO3a at Ser413 amongst other sites. While this phosphorylation event does not alter the localization of FoxO3a, it leads to activation and transcriptional activity of target genes such as Gadd45a.
