Legend has it that the ancients were very tall, such as Kuafu chasing the sun, but later, the human body became shorter, is there any secret hidden in this, and how did scientists reveal it?
At present, there are two genes that are latent in the human body, and they can make humans become huge, but why does the human body seal these two genes, can they be reopened to make the human body taller?
1. The legendary Kuafu.
In ancient times, there was a giant named "Kuafu", his figure was very tall, and the distance between his arms could reach more than ten meters, so he decided to chase the sunset sun, but the sun could not be chased by him, so Kuafu chased all the way to the Yellow River, but the Yellow River was also broken by his feet, so Kuafu had to commit suicide in anger, and his blood turned into water in the Yellow River.
This is a well-known mythical story of Kuafu chasing the sun, but there are many giants with huge human bodies in ancient legends, so will ancient people really be taller than modern people?
If there is really a gene that makes humans taller, why does the human body seal this gene?
However, there is a sealed gene on human chromosome 17, which is also the gene in the human body that inhibits giants, and scientists have found that the P53 gene can inhibit human giantization.
The P53 gene is an important tumor suppressor gene in mammals, which can recognize what is wrong in the human body and then repair those problems, but what is the LIF6 gene in the human body?
The LIF6 gene is a gene that directly clears cancer cells, but the LIF6 gene is derived from the P53 gene that recognizes a cell mutation that has problems repairing and can lead to cancer.
Therefore, the P53 gene in the human body will seal the LIF6 gene, but if the LIF6 gene in the human body is opened, will it make humans become giants?
2. The danger of human giants.
If the LIF6 gene in the human body is opened, it will not turn humans into giants, but humans will cause cancerous diseases due to the rapid increase in cancer cells.
Human height is positively correlated with the risk of cancer, and the higher the person, the greater the risk of cancer, so the risk of opening the LIF6 gene in the human body is very great.
But why is it that the higher the height of humans, the greater the chance of cancer?
This starts with the human P53 gene, the P53 gene in the human body is a protein that repairs cancerous cells, and it has a very important role, which is to continuously clean up cancerous cells and keep our body away from cancer.
But the human body itself will continue to produce cancer cells, which is like our body itself will have some cells that will become cancerous, but the P53 gene will eliminate them.
The human body will continue to produce cancer cells, but the human P53 gene will continue to clean up these cancer cells, so it is very difficult for humans to form cancer, but the human body will continue to produce cancer cells, which is like a vicious circle.
But because the human P53 gene can continuously clean up cancer cells, so eventually this vicious circle will continue to be broken, but if this vicious circle forms the gene of carcinogens, then humans will develop cancer.
However, if humans can turn on the LIF6 gene in their body, the LIF6 gene can clean up cancer cells, and when the P53 gene is not enough to clean up the cells, the LIF6 gene will clean up the cancer cells, which can reduce the chance of cancer in humans.
But once the LIF6 gene is opened, humans will push themselves into another danger, that is, the giant constitution.
3. Can scientists break the seal now?
From now on, although scientists already know how to open the LIF6 gene, they dare not do so, because once the LIF6 gene is opened, the human body will become cancerous, so scientists do not dare to open this seal at will.
But in the field of cancer research, human beings are constantly trying to carry out some new methods, for example, researchers have activated the LIF6 gene, but they have not been activated, this is to keep it, if one day human beings can really overcome cancer, then the LIF6 gene can play its role, and then help humans fight cancer.
However, at present, scientists still have some controversy about the editing of human genes, because many people are afraid that human gene editing will have some unpredictable consequences, so at present, human beings still need some good lifestyle habits to prevent the occurrence of cancer.
Therefore, in our daily life, we need to have good living habits, moderate exercise, reasonable diet, and regular physical examinations, so that they can be detected as soon as possible when cancer comes, and then treated as soon as possible.
