R&D Background: Forkhead Box O4 (FOXO4) is a member of the FOXO subgroup of highly conserved forkhead transcription factors found across mammalian tissues including muscle, nerve, fat and epithelial organs. It acts as a master epigenetic controller that governs cellular aging, response to oxidative stress, energy metabolism and programmed cell elimination. This lab-grade recombinant polypeptide is prepared for in vitro cell signal testing, aging pathway exploration and senescence-related research, widely adopted in biogerontology, cell metabolism and degenerative disease preclinical trials.
2. Core Mechanism of Action
FOXO4 shifts location between the cytoplasm and cell nucleus based on upstream growth factor signals, attaching to conserved FOX response segments on target gene promoters to govern downstream transcriptional networks:
When insulin and IGF-1 levels remain low, FOXO4 gathers inside the nucleus to trigger the expression of antioxidant genes such as SOD and GPx, cutting down excess reactive oxygen substances inside cells and relieving oxidative damage to cell structures;
It controls the expression of genes linked to senescence-associated secretory phenotype (SASP) and cell cycle block signals, serving as a key switch that governs the start and continuous state of cellular aging;
It coordinates the transcription of genes related to sugar and fat metabolism in liver and adipose tissue, balancing energy storage capacity, insulin responsiveness and whole-body nutrient utilization efficiency;
It interacts with p53 cell death signal chains to adjust the critical threshold for cell cycle pause and programmed cell removal triggered by external stress;
It adjusts self-renewal and differentiation signals of stem cells in muscle and nerve precursor cells, which shapes the tissue self-repair ability of organisms as they grow older;
When growth factor signals are abundant, FOXO4 moves out of the nucleus and stays within the cytoplasm, losing its ability to activate transcription and halting the expression of anti-aging and energy-breakdown gene programs.
3. Core Research Efficacy (For Research Laboratory Use Only)
Cellular Senescence & Anti-Aging Mechanism Research
Core lab reagent for exploring the onset of cell aging, SASP release and pathways for clearing aged cells; suitable for testing fibroblast aging and tissue degeneration models related to organ senescence.
Oxidative Stress & Antioxidant Pathway Research
Starts endogenous antioxidant gene programs to counteract cell damage brought by reactive oxygen species, supporting studies on free radical aging, radiation stimulation and oxidative tissue lesions.
Glucose & Lipid Metabolic Regulation Research
Manages the activation of liver sugar-production and fat-generation genes, key experimental raw material for signal tests around insulin insensitivity, metabolic syndrome and energy balance.
Stem Cell & Tissue Regeneration Research
Adjusts proliferation and differentiation signals of precursor cells, applied to research on muscle recovery, neural stem cell maintenance and age-related decline of tissue repair capacity.
Apoptosis & Tumor Suppressor Signaling Study
Works alongside p53 stress response networks to regulate cell survival and growth arrest, auxiliary testing material for DNA damage response and degenerative lesion mechanism analysis.
Supplied as sterile lyophilized powder, SDS-PAGE & HPLC purity ≥95%, mainstream vial specifications: 1mg, 5mg. Every batch is equipped with full COA, MSDS, SDS-PAGE electrophoresis and HPLC chromatogram test documents.
As a lab-use recombinant FOXO transcription factor reagent, FOXO4 acts as a core upstream linkage between growth factor signals, internal antioxidant defense, energy metabolism and cellular aging. Its reversible movement between cytoplasm and nucleus allows researchers to fully analyze the transcriptional chains that drive cell senescence, metabolic imbalance and multi-organ tissue degeneration in diverse cell types.
It serves as essential research material for in-vitro cell culture and tissue model experiments covering biogerontology, senescent cell clearance, oxidative stress resistance, sugar-lipid metabolism and stem cell regenerative biology.
