What affects the aging of the body?
The problems of aging of the body are occupying the minds of scientists - geneticists more and more, because a breakthrough in the field of inhibition of cellular aging would enable people to reverse the processes of wear and tear of the body.
The discoveries of recent years have made it possible to significantly advance in the development of theories of rejuvenation, which was facilitated by studies of the human cellular telomere. Telomere (a term for the end of a chromosome). The telomere is located at both ends of the chromosome, does not carry any useful information for DNA reproduction, but prevents one chromosome from joining another chromosome (or their fragments), thus performing a protective function during DNA replication (duplication).
How do cell telomeres affect aging in the body?
During cell division, a special enzyme telomerase (DNA polymerase) adds repeats (sections of DNA chains), but the terminal sections of DNA (telomeres) do not repeat, but, on the contrary, shorten with each cell division. This process of telomere shortening is called terminal underreplication and is a stumbling block in the aging of the body, since it is actually a biological cause of aging.
An interesting fact has been noted by scientists dealing with aging. People whose skin is prone to acne, triggered by the increased work of the sebaceous glands, have an advantage in matters of aging, as it has been noticed that their leukocyte DNA telomeres are much longer than in people who are not prone to acne.
Today scientists are working on changing the mechanism of underreplication and overcoming it. Elisabeth Parrish, head of aging research at BioViva, is the first patient to be treated with research to influence telomere length by increasing telomerase production. Positive results were recorded.
