Recombinant human FOXO4 (rhFOXO4) is a genetically engineered version of the Forkhead box O4 (FOXO4) protein, a member of the FOXO transcription factor family involved in regulating cellular processes like apoptosis, cell cycle arrest, oxidative stress resistance, and longevity. FOXO4. encoded by the FOXO4 gene in humans, plays a critical role in modulating stress response pathways, particularly through interactions with the insulin/PI3K/AKT signaling cascade. It is known to influence cellular senescence by promoting the survival of senescent cells, which has linked FOXO4 to age-related diseases and cancer.
The recombinant form is typically produced using bacterial or mammalian expression systems, allowing large-scale purification for research and therapeutic exploration. Recent studies highlight rhFOXO4’s potential in targeting senescent cells. For instance, FOXO4-DRI, a designed peptide interfering with FOXO4’s interaction with p53. has shown promise in animal models by selectively inducing apoptosis in senescent cells, alleviating age-related tissue dysfunction. Additionally, rhFOXO4 aids in deciphering FOXO4’s dual role in cancer—acting as a tumor suppressor via stress-induced apoptosis or a promoter in certain contexts by enhancing cell survival. Its study remains vital for developing therapies targeting aging, metabolic disorders, and cancer.
