Where to Buy FOX04-DRI: Vendor Comparison & Research Info

FOXO4-DRI is a synthetic D-retro-inverso peptide developed for research into cellular senescence, aging biology, and senolytic mechanisms. Derived from a segment of the FOXO4 protein, this modified peptide is studied for its ability to interfere with the interaction between FOXO4 and the tumor suppressor protein p53.

Cellular senescence occurs when damaged or aged cells permanently stop dividing while remaining metabolically active. These cells can accumulate in tissues and produce signaling molecules associated with the senescence-associated secretory phenotype (SASP). Researchers investigate FOXO4-DRI as a tool for studying how selective modulation of senescent cells may influence tissue function, inflammatory signaling, and cellular homeostasis.

Unlike peptides primarily investigated for endocrine or metabolic activity, FOXO4-DRI is focused on protein-protein interactions. Preclinical research has examined its ability to disrupt FOXO4-p53 signaling in senescent cells, providing a model for investigating apoptosis and senolytic activity.

Mechanism of Research Interest

FOXO4-DRI is primarily studied in relation to the FOXO4-p53 pathway. Experimental models suggest that the peptide can interfere with FOXO4 binding to p53, potentially altering the survival signaling of senescent cells.

This mechanism has made FOXO4-DRI an important research compound for investigating:

• FOXO4-p53 protein interactions

• Cellular senescence

• Senolytic mechanisms

• Apoptotic signaling

• SASP-related pathways

• Cellular stress responses

• Tissue homeostasis

• Age-associated cellular changes

The effects observed in preclinical models should not be interpreted as evidence of established therapeutic benefits in humans.

Areas of Scientific Research

Cellular Senescence and Aging

FOXO4-DRI is widely studied in models of cellular senescence and age-related biology. Researchers use it to examine how senescent-cell accumulation may influence tissue function and cellular communication.

Research areas include:

• Senescent-cell biology

• Longevity and aging mechanisms

• SASP signaling

• Cellular stress

• Apoptosis

• Tissue homeostasis

• Age-associated inflammation

Tissue Regeneration Research

Experimental studies have investigated whether modulation of senescent-cell populations can influence tissue repair and regenerative processes.

Research models have included:

• Skeletal muscle

• Kidney and renal tissue

• Cartilage

• Connective tissue

• Cardiovascular tissue

• Pulmonary tissue

• Stem-cell environments

These studies aim to clarify the relationship between cellular senescence, tissue repair, and regenerative capacity.

Inflammation and Cellular Signaling

Senescent cells can release a range of inflammatory signaling molecules. FOXO4-DRI is therefore investigated as a tool for studying how changes in senescent-cell populations may affect inflammatory pathways and cellular communication.

Research may examine:

• SASP-associated signaling

• Cytokine activity

• Inflammatory pathways

• Cellular communication

• Oxidative stress

• Tissue-level signaling

Musculoskeletal Research

Preclinical research has explored FOXO4-DRI in models involving skeletal muscle and cartilage biology. These studies investigate how cellular senescence may contribute to age-related changes in muscle function, connective tissue, and regenerative processes.

Organ Aging Research

FOXO4-DRI has also been studied in experimental models of organ aging, including kidney, cardiovascular, and pulmonary systems. Researchers use these models to investigate whether senescent-cell modulation can alter tissue-level responses associated with aging and cellular stress.

D-Retro-Inverso Peptide Design

FOXO4-DRI incorporates a D-retro-inverso peptide configuration. This structural approach reverses the amino acid sequence while incorporating D-amino acids, creating a peptide with altered conformational and enzymatic stability characteristics compared with conventional L-amino-acid peptides.

The modified structure is particularly useful for laboratory research involving peptide stability, protein interactions, and cellular signaling.

Product Format and Quality

FOXO4-DRI is supplied as a lyophilized freeze-dried peptide designed to support molecular stability during storage and laboratory handling.

Quality assessment of research peptides commonly includes analytical techniques such as:

• High-Performance Liquid Chromatography (HPLC)

• Mass Spectrometry (MS)

• Peptide identity confirmation

• Purity analysis

• Batch consistency testing

• Molecular characterization

Proper storage and handling should follow established laboratory protocols to help maintain peptide integrity.
