Buy FOXO4-DRI (Proxofim) (10mg) peptides, this is an experimental synthetic senolytic peptide that selectively triggers apoptosis in senescent cells by disrupting the interaction between FOXO4 and the p53 protein. By promoting nuclear exclusion of p53, it eliminates damaged aging cells and restores tissue function without harming healthy cells . [1, 2, 3]
Mechanism of Action
In senescent cells, the FOXO4 transcription factor localizes next to activate p53, preventing p53 from inducing programmed cell death (apoptosis). [1, 2]
  • Disruption: The peptide mimics the native FOXO4 domain and competitively blocks the p53-FOXO4 interaction. Buy FOXO4-DRI (Proxofim) (10mg) peptides
  • Apoptosis: This interference allows p53 to migrate to the mitochondria, which selectively kills the senescent cell while sparing healthy cells. [1, 2]
Potential Applications
Research on animal models shows promising, yet preliminary, results regarding age-related degradation: [1]
  • Vascular Function: Studies show it can suppress aortic aging and alleviate endothelial cell senescence.
  • Testicular Aging: It has been observed to target senescent Leydig cells, alleviating age-related testosterone decline and improving spermatogenesis in aged mice.
  • Fibrosis: Research indicates it may help in resolving conditions like pulmonary fibrosis and keloid senescent fibroblasts. [1, 2, 3, 4, 5]
