Using FOXO4-DRI to eliminate senescent cells
One in 10 adults over 65 will have dementia. That equates to 10 percent of senior individuals being told they have a degenerative illness that is brought on by the natural decline of the body that comes with becoming older. Isn’t it really bonkers? But have you ever given any thought to the reason why?
Why do we age?
Because there are so many different elements at play in the ageing process, that is an extremely open-ended topic to ask. The process of cellular senescence is one of the most important factors. The process known as cellular senescence begins when your telomeres are said to have “ran out.”
During cell division, the cells duplicate the DNA that is contained in their chromosomes. Sadly, there are a lot of problems with this procedure, and at the end, some of the DNA is discarded (insert dramatic gasp). Don’t be concerned because the telomeres that are located at the very end of each of our chromosomes are here to save the day.
Telomeres are similar to the aglets that are found at the end of our shoelaces, with the exception that they shorten over time. They are non-essential DNA, and with each cell division, a somewhat larger portion of them gets removed (they can typically withstand 50 to 70 divisions). ‘Running out’ of telomeres triggers the release of telomeric signals, which transforms cells that were previously healthy into senescent cells.
Senescent cells are non-dead cells (which should be dead) that are missing a protein that signals them when it is time to die. These cells are said to be senescent. They are one of the primary contributors to the ageing process.
Consider your body to be a machine, and think of senescent cells as the rust that accumulates on the moving parts, preventing them from working properly. There are many people who have made it their life’s work to discover a solution to this problem, and researchers have made significant progress.
Throughout the course of medical history, there has never been a foolproof method to get rid of senescent cells. The unfortunate truth is that there is a possibility that there will never be again. However, there has been and will continue to be ongoing progress done, so perhaps one day there will be. One of the currently available options is this one, which is quite close to being ideal.
FOXO4-DRI is the name of the therapy that is being utilised. Now, for those of you who recognised the name of the peptide that was mentioned in the headline of my post, the answer is that this was tested on mice. (as I discussed in one of my earlier posts titled “How to make mice survive for a longer period of time”)
I said that it may be dangerous, but that was before I found out that it has been tested on people in addition to mice. Since then, I have learned that it is safe for both species.
An investigation was conducted under the heading “Targeted Autophagy of Denatured proteins Cells Restores Tissue Homeostasis in Response to Chemotoxicity and Aging,” which was carried out by a group of researchers. They utilised a peptide known as FOXO4-DRI in order to bring about the death of senescent cells. This was accomplished by limiting connections that senescent cells had with a gene known as p53 and FOXO4.
So, tell me, what exactly is FOXO4-DRI? There is a straightforward response to that inquiry. A senolytic is what FOXO4-DRI is. The term “senolytics” comes from the words “senescence” and “lytic,” which mean “to destroy.” These therapies are now being studied to see whether or not they may trigger the death of senescent cells without also destroying healthy cells in the process.
It’s possible that this senolytic is a miracle worker. However, before you jump to any assumptions, let me to describe how this situation unfolds.
FOXO4-DRI is essentially a peptide that is injected into your body. Peptides are short chains of chemicals that are part of the amino group and are joined together by peptide bonds. It then locates the FOXO4 gene, which is an abbreviation for the forkhead box O4 gene, and it interacts with that gene to prevent any communication with the p53 gene. This causes senescent cells to undergo apoptosis, which is the process of cell death.
The amount of senescent cells that develop as a result of your condition might be reduced by using FOXO4-DRI to split FOXO4 and p53.
FOXO4-DRI is the most dependable and efficacious of all the senolytics that are currently the subject of investigation. Those who aspire to lead lives that are healthy and disease-free might stand to benefit tremendously from its use (everyone). It’s possible that ten percent fewer elderly people would get dementia if this were implemented. Would it be possible to cut this down to 1 percent? 0.1 percent ? It’s feasible that FOXO4-DRI will make this achievable.
Someone who knows me well once posed the following question to me: “Since you’re conducting all this study on longevity and finding ways to live longer, do you want to live forever?” I am aware that you may be anticipating some epic and thought-provoking response from me, but the fact is that I do not have one.
Initially, I was at a loss for words, but after giving it some consideration, I’ve come up with a response. Even while I don’t necessarily want to live forever due to the fact that there are so many drawbacks, it doesn’t mean that I don’t want to tackle diseases that are associated with ageing.
This isn’t just about surviving forever; it’s also about enjoying a life that’s disease-free and healthy in the meanwhile. I hope that you haven’t come to the conclusion that a long and happy life are necessarily synonymous with one another. It’s all about the quality, not the number.
If there was one thing that I wanted you to go away with after reading this post, what would it be?
Senolytics are therapies that are now being investigated to see whether or not they may bring about the death of senescent cells without also causing the loss of healthy cells in the process.
FOXO4-DRI is a powerful senolytic that is also a peptide that binds with FOXO4 to halt any communication with the p53 gene. This causes apoptosis to be triggered in senescent cells.
By lowering the number of senescent cells we produce, this may make it possible for us to live a life free from sickness and illness.
