After staying in the prairie for a few more days, Ye Li was about to return to the west. Of course she needed Ye Xing as a full-time driver, but this time she brought Ye Xiaozi, Ye Xiaoming, and the white fox with her.
The two eldest children are already in their twenties. In fact, they are not young anymore. Standing in front of their parents, they are like brothers and sisters. Only because they have been cultivating since childhood, they look younger.
In the East, the two of them are already at an age where they should be discussing marriage, but as they are cultivators, they really can't ask for it. The key is that with the arrogance of the two children, it is probably difficult to find a suitable candidate. .
One day later, when he returned to Lan Bo City, Ye Xing gave the two children some newly refined foundation-building elixirs and some self-defense equipment, and let them travel.
Ye Xiaozi and Ye Xiaoming now have six levels of foundation building cultivation, and they have a new type of spiritual energy gun for self-defense. Ye Xing is not worried about their safety.
Moreover, Ye Li is now in charge of secret guards in dozens of countries in the far west. If you are willing, you can quickly get the exact whereabouts of the two of them. The key is that the two of them have long-wave telephones with them and can contact them at any time.
As a hands-off person, Ye Xing no longer interfered with anything about Lixing Group. He basically stayed in his laboratory, doing research on biotechnology.
Ye Xing has conducted cell structure analysis on hundreds of species of animals and plants, conducted the most detailed research on various human bodies in this world, and already has a human genetic map.
The research that was interrupted by various things was picked up again. This time, Ye Xing asked everyone not to disturb him, determined to understand the mechanism of life's aging, and it would be best to prepare a drug that can maintain youth forever.
The reason why this research was done in the first place was also requested by Ye Li. She is forty years younger than the Qin sisters, but she still looks much older than the two girls.
Ye Li has been nagging about this matter, which is her only dissatisfaction with Ye Xing. She always teases Ye Xing and calls herself a miracle doctor?
Ye Xing also saw the desire of his daughter Ye Xiaozi. In fact, all women want to be young and beautiful forever. Ye Xiaozi and her mother are absolutely like sisters when they stand together.
But for a while, they can't go back to the small space of the elixir. If they go back, they may not know what they have eaten to keep the four of them from aging for a long time.
Thinking that I have the scientific and technological knowledge of the previous life on the earth, I actually know the mechanism of cell aging. If I compare it now and study the mechanism of cells, I can also create anti-aging drugs.
There was another reason that made Ye Xing even more determined. Ye Mu's face had already aged very much and her body seemed to be fine. However, at nearly ninety, her face looked very old.
There is certainly no immortal person in the world, but it is also good to look better and have a more wonderful daily life when you are alive.
At the same time, it is also what Ye Xing wants to do. Moreover, this really involves the improvement of the efficiency of spiritual energy conversion into true energy that he is researching.
It took twenty days to build a new laboratory in a cave at the back of the Royal Academy and set up the most stringent protection formation.
Such strict security measures are not due to confidentiality, but because Ye Xing has raised many, many small animals inside, all for experimentation.
Biochemical experiments are extremely dangerous. If you are not careful, it is very likely to cause a terrible disaster. He does not dare to mess with it, at least he must be extremely cautious.
It was really not a joke. From the memory of the super intelligence, Ye Xing found the biochemical knowledge that had been understood and solved on the earth in his previous life, and then compared and studied the life in this world.
The technology of the premortal earth has clearly understood all the biochemical processes of life's birth, growth, and aging, and has corresponding countermeasures. Now it is just a matter of re-experimenting, testing, and comparing based on the characteristics of life in this world.
From the knowledge reserve of super intelligence, Ye Xing fully understands that the reason why the cells of major life forms on the earth age is actually caused by several mechanisms of biochemical processes inside the cells:
1. Aging caused by DNA replication, lack of telomerase activity in cells, and as the number of cell divisions increases, telomeres gradually shorten, which means DNA is damaged and DNA cannot replicate normally.
Lack of telomerase also significantly increases the content of intracellular inhibitory factors, which in turn induces the expression of intracellular vitality factors, overactivates biochemical processes within cells, and triggers cellular senescence.
2. Aging induced by environmental stress: External stress conditions can also shorten the lifespan of cells and promote cell aging, mainly oxidative damage. Aging is caused by damage caused by active oxidative components produced by metabolism during life activities.
3. Telomeres become shorter every time DNA is replicated. This means that once a cell divides, the telomeres become shorter. As the number of divisions increases, the telomeres slowly disappear. When a critical point is reached, the telomeres cannot protect the DNA, and this occurs. The DNA replication errors described above result in mutated cells.
4. Mutated cells will activate the expression of another inhibitory enzyme, thereby inhibiting the cell cycle, causing the cells to enter senescence, and the cells will soon undergo apoptosis.
5. When cells are damaged or mutated, aging will be accelerated. Oxidative free radicals will damage DNA. If cells cannot repair the damage, they will age.
If telomerase is overactivated at this time, cells may become immortal, but this is also a manifestation of tumors.
6. Tumor cells can replicate endlessly. In fact, there are biochemical abnormalities within the cells, problems with the environment and DNA replication, and the telomerase level is too high, but the DNA telomeres will not become shorter.
The animals used in Ye Xing's experiments are generally simple creatures that grow and age quickly, with a lifespan of only a dozen days, so observation and comparison will yield results quickly.
Sure enough, the length of life mainly depends on the biochemical processes inside cells, not entirely on inherited DNA.
Let's put it this way, there is not much difference in the DNA between people, and the life span should be the same, but the reality is that the difference is huge. The real reason is determined by the biochemical process inside the cell, that is, it depends on the interaction of certain active enzymes. effect.
Ye Xing also used a newly developed electron microscope to observe and compare his own cells with other people's cells, cells from animals and plants, and cells from white foxes, and indeed he made a major discovery;
The cell division and aging process of ordinary people is very fast, but the process of cell division and aging of cultivators is several times slower. Taking skin as an example, the epidermal cells of ordinary people generally divide once a month. As for Ye Xing and White Fox, they only split once a year.
The cell aging process of cultivators is slower and the production of free radicals is very small. Due to daily cultivation, most of the free radicals are basically eliminated every day and the cells are repaired.
Compared with Ye Li and others, after the oxidative free radicals are generated inside Ye Xing's cells, there is a mechanism that quickly removes them. This is the fundamental reason why Ye Xing, Qi Ming and others do not look older.
The four people in the small space of elixirs indeed took one or more elixirs, which caused the cells in the body to produce a mechanism to remove oxidative free radicals and repair cells. That is, a specific active enzyme is higher than Others are a hundred times better.
Ye Xing also remembered that the ice silkworms and ice bear worms found in the Arctic Icefield ten years ago could survive hundreds of years without eating or drinking. He didn't know what the internal mechanism was.
He immediately took out an ice bear insect from the space ring and conducted a detailed dissection and comparative study of the internal components of the cell. A month later, he finally had a clear answer;
In addition to the special structure of the ice bear cells, the fundamental reason for its long life is that the biochemical processes inside its cells are extremely slow and will automatically remove various harmful substances inside the cells.
Its cells can maintain the same acid-base level for a long time, and they also have a similar active enzyme with an extremely high content.
Ye Xing tried to extract this enzyme from the body of the Ice Bear Bug. After half a month of hard work, he actually extracted a tiny bit, stored it in a jade bottle, and mixed it with Bingling Crystal Liquid to keep it active.
We also used some cells from animals with extremely short lifespans to test. We used a very fine syringe under a microscope to take a tiny drop of active enzyme solution and inject it into the cells. Sure enough, the cells with only two days of life died. Thirty times more.
At the same time, Ye Xing also tested the cells of dozens of other animals. It was obvious that the biochemical processes of the cells had mutated, generally becoming slower and lifespan longer, and in the worst cases, the cells were more than ten times longer.
Experiments were also conducted on other people's somatic cells. Sure enough, after injection of the inhibitory enzyme, the cell activity changed, the damage was quickly repaired, and the biochemical activity level inside the cells dropped a lot.
Compared with own cells, the active enzymes extracted from ice bear worms are much more effective, which is likely to be a method of longevity of cells.
It’s just that there are trillions of cells in the human body. It is impossible to use this injection method. It is still necessary to activate the content and activity of this enzyme in the body and permanently change the specific active enzyme and acid-base levels inside the cells.
In other words, the issue of longevity at the cellular level is actually completely clear. It just requires how to permanently change the biochemical indicators inside the cells and increase the content of specific active enzymes.
