Deacetylation of
FOXO3 by Sirt1 or SIRT2 leads to Skp2-mediated FOX03 ubiquitination and degradation.
FoxO3 coordinately activates protein degradation by the autophagic/lysosomal and proteasomal pathways in atrophying muscle cells.

Foxo3 gene expression and oxidative status in beta-thalassemia minor subjects.
A cross-talk between stromal cell-derived factor-1 and transforming growth factor-beta controls the quiescence/cycling switch of CD34(+) progenitors through
FoxO3 and mammalian target of rapamycin.
Cyanidin increased SIRT6 enzyme levels in human colorectal cancer cells, and it was also discovered to decrease the expression of the Twist1 and GLUT1 cancer genes, while increasing the expression of the tumour suppressor
FoXO3 gene in cells.
PGC-1alpha protects skeletal muscle from atrophy by suppressing
FoxO3 action and atrophy-specific gene transcription.
Additionally, mTOR enhances the NF-[kappa]B signaling pathway by downregulating expression of
FOXO3, suggesting an ability to inhibit autophagy [75].
