Buy FOXO4-DRI Peptide

FOXO4-DRI is a special type of peptide. It helps break the link between FOXO4 and p53. This action can remove old and unhealthy cells called senescent cells. When these cells die, it may help refresh tissues and lower diseases linked to aging. Researchers mainly study this peptide to understand its effects on aging and cell health.

Buy FOXO4-DRI for Research Purposes

FOXO4-DRI is a unique synthetic peptide. It acts as a senolytic agent in a special way. It interrupts the connection between the FOXO4 protein (forkhead box O 4) and p53. p53 plays a key role in how cells deal with stress.

In healthy cells, FOXO4 binds to p53. This helps older or damaged cells live longer. It prevents p53 from triggering cell death [1]. However, FOXO4-DRI breaks this bond. This lets p53 go free, allowing it to do its job. When p53 is active, it leads to cell death. This process helps get rid of senescent cells [2].

This process aims to remove old cells, known as senescent cells, while keeping healthy ones safe. This helps slow down aging and reduces cell damage. By eliminating these aging cells, FOXO4-DRI could improve tissue health and functions of cells. It might also help delay or reduce diseases related to aging [3].

Researchers are exploring it for anti-aging treatments. These treatments work against the bad effects of cellular senescence, such as inflammation and the decline of organs over time.

FOXO4-DRI Peptide Benefits

Previous studies have suggested that FOXO4-DRI may have the following benefits:

  • Selective Removal of Senescent Cells – FOXO4-DRI specifically targets and removes senescent cells by disrupting the FOXO4-p53 interaction, inducing apoptosis in these aged or damaged cells without harming healthy ones [3].
  • FOXO4-DRI enhanced tissue rejuvenation – By clearing out senescent cells, FOXO4-DRI can cause a significant increase in the regeneration of tissues and may restore their functionality, making it a promising agent for reversing cellular aging effects [4].
  • Improved cellular function – The removal of dysfunctional senescent cells allows healthy cells to perform better, improving overall tissue maintenance and repair processes [4].
  • FOXO4-DRI may reduce age related inflammation – Senescent cells often release pro-inflammatory factors known as the senescence-associated secretory phenotype (SASP). By eliminating these cells, FOXO4-DRI helps to reduce chronic inflammation associated with aging, including articular cartilage [5].

Clinical Research FOXO4-DRI

FOXO4-DRI peptide is a key focus in studies about aging and healing. It can focus on senescent cells. This peptide was first made as a senolytic agent. It works by blocking the link between FOXO4 and p53. This action causes the bad cells to die while keeping the good cells safe [1].

Early research, mostly done on different groups of older mice, found that FOXO4-DRI can help heal tissues, make organs work better, and reduce inflammation related to aging [6]. These studies showed that the peptide can reduce the bad effects of something known as the senescence-associated secretory phenotype (SASP). SASP leads to long-lasting inflammation and harm to tissues.

Current research is still trying to find out how it can help with age-related diseases like osteoarthritis and brain diseases [6]. However, there are still some challenges. We need to learn how safe it is over a long time and understand the specific biological pathways that are involved.

Frequently Asked Questions about FOXO4-DRI Peptide

What are senescent cells?

Senescent cells are old or damaged cells. They stop dividing and cannot grow anymore. This occurs naturally due to several reasons. These reasons include DNA damage, oxidative stress, or the shortening of telomeres. While these cells remain active metabolically, they do not support healing or tissue growth.

Senescent cells can play a role in cancer prevention. They help stop damaged cells from dividing too much. However, over time, the number of senescent cells can also be harmful. A major issue is that they let out substances that cause inflammation. This is called the cell senescence associated secretory phenotype (SASP factors). This release results in long-term inflammation, issues with tissues, articular cartilage injuries and age-related diseases. Some of these diseases are osteoarthritis, fibrosis, and heart problems.

Recent studies have examined how to treat senescent cells using therapies like the FOXO4-DRI peptide. This treatment is designed to eliminate unhealthy cells. By removing them, scientists aim to make tissues feel younger, reduce inflammation, and slow down aging. These findings show promise for new methods to combat aging and improve health as we grow older.

How can FOXO4-DRI help knee joints?

FOXO4-DRI is a senolytic peptide that has shown potential in treating knee joint issues by targeting and removing senescent cells. These cells accumulate with age and contribute to various age-related diseases, including those affecting the joints. Research indicates that FOXO4-DRI can selectively remove senescent cells in chondrocytes, which are the cells found in cartilage. This removal can have a significant difference in the function of these cells and potentially restore cartilage health, thereby improving joint function and reducing leg pain [1].

Are there any adverse effects associated with FOXO4-DRI?

The potential side effects of the FOXO4-DRI peptide include treatment-emergent adverse events such as upper respiratory infections, bronchitis, and gastrointestinal issues like nausea and diarrhoea. Additionally, while FOXO4-DRI has been shown to limit chemotoxicity in certain contexts, its overall safety profile in humans requires further research to fully understand all potential side effects.
