[10] showed that folks with shorter telomeres had drastically lousy survival due to greater mortality level caused by heart and infectious diseases. Progressive shortening of telomeres brings about senescence, apoptotic cell Demise, or oncogenic transformation of somatic cells in numerous tissues.
In mammals, maintenance in the linear chromosome ends (or telomeres) consists of faithful replication of genetic components and security in opposition to DNA damage indicators, to be certain genome balance and integrity. These responsibilities are completed from the telomerase holoenzyme and a unique nucleoprotein structure where an variety of telomere-associated proteins bind to telomeric DNA to type Distinctive protein/DNA complexes. The telomerase intricate, which happens to be comprised of telomeric reverse transcriptase (TERT), telomeric RNA component (TERC), and various assistant factors, is to blame for adding telomeric repeats for the finishes of chromosomes.

Many of these broken cells die out naturally, but sometimes it transpires that the telomere mechanism is broken and the cancer cells begins replicating even though it Commonly should not anymore and varieties a tumor (This really is why cancer lines we extracted from dead folks and use in labs are immortal - since the telomere system is harmed whilst human cells aren't). So no "doping" telomerase to daha fazla bilgi create human immortal most perhaps would not perform (that's style of unhappy).

A ribonucleoprotein that takes advantage of its RNA like a template to synthesize TTAGGG repeats, therefore extending telomeres.
They found that individuals who had genetic predictors of extended telomere length ended up far more likely to convey that men and women tended to Believe they seemed young than their age.
Odds ratios (ORs) and ninety five% CIs for each SD minimize of telomere length are provided. Only phecodes that remained major after adjustment for multiple testing are shown. NOS suggests not normally specified.

Halbuki anne kaç yaşında hamile kalırsa kalsın doğan bebek, sıfır yaşında ki telomere sahio olarak dünyaya gelmektedir.
Bu bulgular göz önüne alındığında, cevabın basit olduğunu düşünebilirsiniz: telomeraz ne kadar aktifse ne kadar uzunsa o kadar iyidir. Bununla birlikte, ideal telomeraz aktivitesi aralığı veya ideal telomer uzunluğu konusunda bilimsel bir fikir birliği yoktur. Telomer uzunluğu tuhaf ve tartışmalı bir araştırma alanıdır ve uzun telomerlerin çalışmaya ve referans çerçevesine bağlı olarak olumlu ve olumsuz etkileri olduğu görülmektedir.
In vertebrates, chromosomal finishes encompass TTAGGG repeats with the longest telomeres becoming in rats and some strains of Mus musculus
