Nobel rewards awarding to three American scientists physiologically or medically this year
According to the report of Beijing (Xinhua) the 5th October ' Reporter Pan Zhi) Birth and old age,sickness and death, perhaps this is a generalization most succinctly of a human life, among them but contain countless secrets. How obtain 3 American scientists of Nobel's physiologic or medical award in 2009, relied on " to discover telomere and telomere enzyme to protect chromosome " This achievement, it is old and feeble and suffering from the secret of the serious disease of cancer,etc. to reveal the mankind. In the nucleus of the living beings, there is a linear material apt to be dyed by the alkaline dyestuffs, they are known as " The chromosome " . Normal people's body cells have 23 pairs of chromosome, they are significant to the human life, such as as everyone knows, that determined men and women's gender is a pair of chromosome. The part has a special structure like cap at the end of the chromosome, this is a telomere. But the function of telomere enzyme is to help to formate telomeres, make the length of the telomere waited for structurally and be stabilizedded. "The chromosome takes hereditary information. The telomere is the terminal chromosome ' protect caps ' in cells, it can protect the chromosome, telomere enzyme can resume its length when the telomere is damaged. " Introduce, are " accompanied by the growth of people in Elizabeth Blackburn one of the award-winners, the telomere is abrades gradually. Then will we ask, is this very important? And we find gradually, this is really very important for mankind. " The press Communique that Carol card medical college of forest Sri Lankan releases is spoken, these 3 scientists' discovery has " explained how telomeres protect how end and telomere enzyme of the chromosome formate telomeres " . Work through their initiative, nowadays people know, the telomere is not merely closely related to individual character speciality and stability of the chromosome, and involve life-span of cells, old and feeble and death,etc.. To be simple, the telomere is shortened, cells wear out. On the contrary, if the enzyme activity of the telomere is very high, the length of the telomere can be kept, the aging of cells is delayed. But need to point out, discover successively in recent years, though telomere and chromosome,etc. relate to the fact that cells wears out, and then influence is old and feeble, but not the only factor. "It is a very complicated process that the life is old and feeble, it has a lot of different influence factors, the telomere is only one of them. " "This is about an important one in the puzzle jigsaw in research such as the mankind is old and feeble, cancer and stem cell. " The press Communique is said, " their discovery makes our understanding of cell increase new linking degree, have clearly revealed the mechanism of disease, and will impel us to develop the potential new treatment.
