Telomere Test (ตรวจวัดความยาวเทโลเมียร์)
Chromosome is a repository of genetic information of an individual which controls and transmit information related to the genes of living organisms such as complexion, eye color and hair color. Every human cell has 46 chromosomes: 23 chromosomes from the mother and 23 chromosomes from the father. The protective structure is located at the tip of each chromosome, called ?telomere?. It is comparable to a lace that at the end there is a plastic strap to prevent fraying of the rope. So is a telomere for the chromosome, to protect genes within the chromosome.
Telomeres shorten?as a person gets older. However, if it becomes too short, it can no longer be divided. This will cause the deterioration of cells, bodily organs and aging, including greater possibilities of illnesses. By analyzing the length of the telomere individuals may gain insights into their health, lifespan and susceptibility to diseases, such as cancer and Alzheimer’s.
The maximum length of the telomere is during the stage of fetus or embryo with approximately 15,000 base-pairs, whereas it decreases to 10,000 base-pairs at birth and 8,000 base-pairs at the age of 20 years, while by the age of 50 years it will reduce to about 7,000 base-pairs. It will gradually decrease at 50-100 base-pairs each year until there are only 4,000 base-pairs at the age of 100 years.
Telomere Test intends to reveal a person?s biological age. If it is discovered that the telomere is shorter than the average, we have a way either to increase the length of telomere, or decelerate the shortening of it.
