mTORC2 Is the Major Second Layer Kinase Negatively Regulating FOXO3 Activity.

Forkhead box O (FOXO) proteins are transcription factors involved in cancer and aging and their pharmacological manipulation could be beneficial for the treatment of cancer and healthy aging. FOXO proteins are mainly regulated by post-translational modifications including phosphorylation, acetylation and ubiquitination. As these modifications are reversible, activation and inactivation of FOXO factors is attainable through pharmacological treatment.

Screening Health-Promoting Compounds for Their Capacity to Induce the Activity of FOXO3.

Several chemical compounds including natural products have been suggested as being effective against age-related diseases or as beneficial for a healthy life. On the other hand, forkhead box O (FOXO) proteins are emerging as key cellular components associated with extreme human longevity. FOXO proteins are mainly regulated by posttranslational modifications and as these modifications are reversible, activation and inactivation of FOXO are attainable through pharmacological treatment.

Therapeutic strategies targeting FOXO transcription factors.

FOXO proteins are transcription factors that are involved in numerous physiological processes and in various pathological conditions, including cardiovascular disease, cancer, diabetes and chronic neurological diseases. For example, FOXO proteins are context-dependent tumour suppressors that are frequently inactivated in human cancers, and FOXO3 is the second most replicated gene associated with extreme human longevity. Therefore, pharmacological manipulation of FOXO proteins is a promising approach to developing therapeutics for cancer and for healthy ageing.
