Why do we grow old to reveal the secret! The Mystery of the Nine Causes of Aging!
Why do we age? This is a question that many people are asking. Recently, scientists have given an answer to this question.
Article 1: There is an error in DNA replication. We must know that our body replaces a large number of cells every day. These cells are actually repeating the relationship between replicating and being replicated. However, as time goes by, some DNA may be misspelled, and these DNA may If it is accidentally inserted or deleted, what will happen at this time? At least it will cause pathological changes in the body mechanism, and at the worst it will produce cancer cells. Scientists have found that there are a large number of damaged cells in the body of the elderly. These cells are the result of incorrectly copying information. If we find a way to repair these cells, we may be able to extend lifespan.
The second article: Gene expression error, gene expression refers to DNA is interpreted as a certain performance of the body, and this behavior is controlled by proteins, as our body ages, these proteins become loose and become somewhat unable to express correctly or Silencing, which means that some proteins are not produced, and what is more troublesome is that once this silencing is understood as mismanufacturing, it will cause cells to mutate. If we reverse these cells, it will improve our neurons very well, thereby reducing Memory loss.
The third one: Chromosome shortening, there is a telomere at both ends of the chromosome, which is used to replicate DNA, as our body ages, this telomere will continue to wear out, and eventually lead to loss of function, once the telomere is exhausted, the cell If we find ways to improve telomere recovery, we can change this situation. At present, scientists have found a way to increase the level of telomerase in mice.
Article 4: Protein degradation. In cells, protein is continuously produced. It is an important source of energy supplement and activity for cells. Protein must be renewed regularly in cells, but as time goes by, this function becomes more and more serious. Slower and even stagnant, when these useless proteins continue to accumulate, they will become toxic, and the cells will naturally not be able to continue. Scientists have found through research that the accumulation of these useless proteins is one of the main causes of Alzheimer's disease, that is, old age dementia.
Article 5: Aging cells do not die. When the cells in our body are destroyed, they will show a strong desire to survive and refuse to die. These are zombie cells. Their appearance will cause inflammation in our body organs. These zombie cells are senescent cells. This has become a vicious circle. After aging, the cells will age, and these aging cells will accelerate the aging of the body. Scientists say that if these aging cells are improved or eliminated, we can restore our body vitality and naturally prolong our life.
Article 6: Mitochondrial dysfunction. Aging also changes the level of intercellular communication in the entire endocrine and neuroendocrine system. Information originally transmitted through hormone molecules circulating in these systems, such as insulin, is often lost. In the human body, mitochondria are The porter, which transports our energy and oxygen to our body tissues, its passive sabotage will cause the destruction of cellular proteins, which will trigger a series of reactions in the body, but scientists have found a way to restore mitochondrial function.
Article 7: Metabolism is out of control. As people age, many people begin to gain weight and lose shape. The reason is that cells become less and less accurate in detecting the content of glucose or fat in the body, so some fats and sugars cannot be properly consumed. deal with. Excessive fat accumulation in aging cells is not because the elderly eat too much fat, but because the cells cannot digest fat normally. Once this function goes wrong, it will lead to diseases such as diabetes.
Article 8: Tissues stop renewing. We must know that our bodies often wear and tear. Under normal circumstances, our bodies will repair themselves. However, as we age, this function begins to strike. The main reason is that stem cells are exhausted. , In fact, it is not completely exhausted, but the stem cells lack activity and become a little passive and sabotage.
Article 9: Cells have stopped communicating and interacting with each other. In order for the body to function normally, cells must constantly communicate with each other. They transmit signals through the blood and immune system. But as our bodies get older, the ability of cells to communicate also deteriorates, and some cells become unresponsive. In addition, the appearance of senescent cells destroys this function. Aging also changes the entire endocrine and neuroendocrine system. At the level of cell-to-cell communication, messages that would otherwise be conveyed through hormone molecules circulating in these systems, such as insulin, tend to be lost.
