As cellular division slows, it undergoes a progressive deterioration known as senescence, which we commonly refer to as aging. Inside the telomeres cancer to human aging booklet nucleus of a cell, our genes are telomeres cancer to human aging booklet arranged along twisted, telomeres cancer to human aging booklet double- stranded molecules of dna called chromosomes. At the ends of the chromosomes are stretches of dna called telomeres, which protect our genetic data, make it possible telomeres cancer to human aging booklet for cells to divide, and hold some secrets to how we age and get telomeres cancer to human aging booklet cancer. New genomic research led by uc san francisco scientists reveals that two common gene variants that lead to longer telomeres – the caps on chromosome ends thought by many scientists to confer health by protecting cells from aging – also significantly increase the risk of developing the deadly brain cancers known as gliomas. It is important to note that, despite the increasing realization that telomeres are important in human aging and cancer, the actual amount of information on telomere length in different human telomeres cancer to human aging booklet cell types of normal individuals in relation to their age is surprisingly modest. Thus the telomeres cancer to human aging booklet field is relatively “ data poor. Telomeres & aging. Telomeres may be correlated to the human aging process. Scientists speculate that as telomeres get shorter the signs of aging— gray hair, wrinkles, weaker bones, slower reaction time, etc.

— become more apparent. The theory is that telomere shortening results in aging telomeres cancer to human aging booklet of the entire organism, not only at the cellular level.
