Forkhead box O1 (FoxO1) is a transcriptional regulator of cell growth and proliferation controlled by a receptor tyrosine kinase signalling pathway (the vascular endothelial growth factor A (VEGF-A)/phosphatidylinositol-3-OH kinase (PI3K)/protein kinase B (PKB/Akt) pathway). FoxO1 is phosphorylated in the DNA binding domain at serine 218 by aPKCλ. FoxO1 Ser218 phosphorylation and aPKC expression correlate with poor patient prognosis in various cancers.

VEGF/PI3K/Akt signalling results in FoxO1 cytoplasmic localisation and its inactivation. Cytoplasmically localised FoxO1 is associated with cellular myelocytomatosis (c-Myc) expression and endothelial cell (EC) proliferation. Abnormal atypical protein kinase C (aPKC)/FoxO1/c-Myc signalling contributes to excessive EC proliferation in angiosarcoma and when constitutively active, FoxO1 leads to lethality due to heart defects.
