Description

FOXO4-DRI is a cell-permeable peptide antagonist that blocks the interaction of FOXO4 and p53. FOXO4-DRI is a senolytic peptide that induces apoptosis of senescent cells[1].

In Vitro

FOXO4-DRI (25 mM; 3 days) causes nuclear exclusion of active p53 and induces apoptosis in senescent TM3 Leydig cells[1].
FOXO4-DRI (25 μM; 5 days) significantly reduces the senescence level in PDL9 cells[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Viability Assay[1]

Cell Line: Senescent Leydig cells
Concentration: 25 mM
Incubation Time: 3 days
Result: Reduced the viability of senescent as compared to normal TM3 Leydig cells.

Apoptosis Analysis[1]

Cell Line: Senescent Leydig cells
Concentration: 25 mM
Incubation Time: 3 days
Result: The apoptosis rate increased from 10% to 27%.

Western Blot Analysis[2]

Cell Line: PDL9 cells
Concentration: 25 μM
Incubation Time: 5 days
Result: Decreased the protein levels of representative senescent markers, including p16, p21, and p53.

RT-PCR[2]

Cell Line: PDL9 cells
Concentration: 25 μM
Incubation Time: 5 days
Result: Enhanced SOX9 expression, and reduced MMP12 and MMP13 expression.
In Vivo

FOXO4-DRI (5 mg/kg; i.p.; every other day for three administrations) alleviates testosterone secretion insufficiency and improves the testicular microenvironment in naturally aged mice[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Naturally aged male C57BL/6 mice (20-24 months old)[1]
Dosage: 5 mg/kg
Administration: Intraperitoneal injection, every other day for three administrations
Result: Increased serum testosterone levels. Increased levels of both 3β-HSD and CYP11A1. Decreased interstitial SA-β-gal activity and lowered levels of senescence-associated proteins p53, p21, and p16. Decreased the levels of IL-1β, IL-6 and TGF-β.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
