Liz Parrish, a woman who is “dissatisfied” with 25 years thanks to therapy: fraud or revolution?

In the program on September 28, The fourth millenniumJournalist Mamen Sala interviewed Liz Parrishvery controversial scientist who obeyed the experiment for reduce your biological ageThe Iker Himenes was very surprised and attracted that the founder and general director of Viva Science, a company that promises to have tools for Fight agingThe field is almost like an elixir of eternal youth.

For many, Liz Parrish was very bold. For many others, a fool. And in 2015, he decided to go from the United States to Columbia to go through Double genetic therapy Thanks to those who, presumably, have reduced their biological age by more than 20 years. And climbing.

If he went to Colombia, then this was not for the desire of the Arep, and since the FDA, the greatest authority in the field of clinical trials in the United States, denied the experiment that he wanted to conduct. This already gives us tips that Not very reasonable It was. But, as soon as it is done, can we say that it was worth the risk?

The fight against science Liz Parrish

Liz Parrish has long tried to fight the bureaucracy of clinical trials. His son has type 1 diabetes, a disease from which there is no medicine. Yes, there is treatment, usually with insulin. Nevertheless, she discussed for a long time with FDA to approve clinical trials in people gene therapy that can heal diabetesHe did not succeed, and this is no less, because it is impossible to treat with preclinical tests that guarantee sufficient security Go to clinical trials in people.

Gene therapy consists of Change the patient’s genes To stop showing a specific disease. Therefore, this is a subtle procedure. The function of the gene subject to change should be provided very well, because often the same gene can have different functions. It should also be guaranteed that other genes were not affected.

If something was done wrong, that it seems that Jesse Gelsenger, an 18 -year -old boy who died when he participated as a volunteer in the clinical test of genetic therapy from the disease from which he suffered from. Since then, the methods of genetic therapy have improved significantly; But even in this case, They water a lot before going into clinical trials with peopleThere is a lot of legislation, and everything should be done in accordance with it. Therefore, today only 25 Approved by genetic therapy Such institutions as FDA or his European colleague, EMA.

This is not just a matter of bureaucracy

Liz Parrish could not miss all these steps with diabetes of her son, but with his therapy against aging. He asked FDA an experiment in public based on Only a few positive results in miceHe did not succeed in the field, since the fact that something works for mice does not guarantee its effectiveness, and even more so its safety in people. Therefore, he decided to catch himself in his own guinea pig and A trip to Colombia to conduct experiments.

How were you going to turn back the aging?

Liz Parrish passed a double gene -mediated therapy in Colombia in Colombia. The first encourages action Telomerasean enzyme that is responsible for The spread of telomeresThe field in particular, if it is appropriate, he wanted to lengthen the telomeres of the cells of the immune system. As for the second injection, this is a compound that Prevents myostatinProtein, which negatively regulates muscle growth. Let’s look at the function of each of these injections in the treatment of aging.

On the one hand, telomeres are a kind of protective cover that is at the end of the chromosomes. Since the cell is divided, some DNA of chromosomes is lost. This DNA belongs to telomers whose function is nothing more than sacrifice To protect DNA, which has important functions in the cell. Therefore, the survival of cells usually lasts that its telomerer continues. When they are too short, it means that The cell is very aging.

As for myostatin, its inhibiting contributes to Muscle growth and strengtheningClosely connected from good old age. Worsened muscles and short telomeres Acting of markersSo, Liz Parrish wanted to fight both.

He got it?

As Liz Parrish Ikera Himenes explained in The fourth millenniumHis biological age has greatly decreased since he passed this genetic therapy. In 2015, when he received the first two injections, he had 44 yearsHowever, their markers of aging indicated their field Biological age 66. However, after undergoing treatment He quickly went down to 44. And this is not all, since in 2020 he repeated the procedure, and since then his biological age decreased by an average of five years a year. This is currently below 25 years oldSubstitute the field like Benjamin Button.

Is there any evidence outside your statements to Iker Genimenes in The fourth millennium?

Anyone can go to The fourth millennium And tell Ikera Khimenes, who is 25 years old. It is more difficult to demonstrate it with tests.

If we fulfill the search in the scientific literature of Liz Parrish, we will find two research. One was published in 2020, and the other from 2022. 2020 Gene therapy Based on the insertion of an encoding gene of an immunomodulating protein that will help fight certain autoimmune diseasesThe study only sought to check whether the gene was properly expressed and This was done by rats. This has nothing to do with aging or was checked for people.

As for the study of 2022, it was genetic therapy in order to turn back the aging. However, the magazine in which he published it The study answered in 2025 When it was confirmed that this was not done properly.

There is no longer evidence that Liz Parrish’s research is really effective in people. Nevertheless, there are already many people who, conducted by the media of their business, asked him to undergo treatment. Of course, with all the money that implies for your company.

This is very little ethical and can become quite dangerous. Therefore, one of the scientific consultants of the company, George M. MartinHe left his work after Parrish’s trip to Columbia.

Own Maria BlaskoSpanish researcher of the Tolomere Research Leader, who wanted to use Parrish, was alarmed by this event and insisted that this type of method They must be carried out carefully and only with the appropriate permission of the authorities, such as FDA.

In short, what we saw in The fourth millennium It has no reliability. Liz Parrish can charm Iker Jumenses, but for this reason we are talking about a program that has nothing to do with science. To charm scientists, evidence is needed, and this is usually not equal on television.
