FOXO1

The gene on chromosome 13q14.1 which encodes a forkhead family transcription factor that regulates cell responses to oxidative stress. In the presence of KIRT1, it downregulates cyclin D1 and upregulates CDKN1B as required for cell transition from proliferation to quiescence. It may play a role in myogenic growth and differentiation.

Molecular pathology
FOXO1 translocation with PAX3 has been associated with alveolar rhabdomyosarcoma.

Members of the forkhead box O (Foxo) family of transcription factors, including Foxo1 (previously described as FKHR), Foxo3a (FKHRL1), Foxo4 (AFX), and Foxo6, are phosphorylated by insulin/IGF-1 through a PI3K/Akt-dependent pathway and excluded from nucleus to inhibit their transcriptional activity (Accili et al., 2004).

The loss of their phosphatase activity prevents the dephosphorylation of phosphatidylinositol-3,4,5-trisphosphate to phosphatidylinositol-4,5-bisphosphate, which then allows the transfer of phosphate molecule to PDK1 and AKT proteins, allowing the activation of MDM2, GSK3, P27, P21, CASP9, BAD, FKHR, IKK, and MTOR genes (Figure 1).
