Leukocyte telomere length: the telomere tale continues.
In culture, replicating human somatic cells display progressive telomere shortening. Ultimately, such cells either undergo apoptosis or enter a state of replicative senescence that is triggered by critically shortened telomeres. Accordingly, telomere length is an index of both the replicative history and the replicative potential of human somatic cells in culture (1). Most replicating human som...
متن کاملTelomere Length and Aging
Telomeres, the TTAGGG tandem repeats at the ends of chromosomes, become progressively shortened with each replication of cultured human somatic cells (reviewed in Wong and Collins (Wong & Collins 2003)) until a critical length is achieved, at which point the cell enters replicative senescence. This situation can be reversed by the enzyme named telomerase that is responsible for Telomere Length ...
متن کاملTelomere length kinetics assay (TELKA) sorts the telomere length maintenance (tlm) mutants into functional groups
Genome-wide systematic screens in yeast have uncovered a large gene network (the telomere length maintenance network or TLM), encompassing more than 400 genes, which acts coordinatively to maintain telomere length. Identifying the genes was an important first stage; the next challenge is to decipher their mechanism of action and to organize then into functional groups or pathways. Here we prese...
متن کاملTelomere length and reproductive aging
BACKGROUND Rate of reproductive aging may be related to rate of biological aging. Thus, indicators of aging, such as short telomere length, may be more frequent in women with a history suggestive of premature reproductive senescence. METHODS Telomere-specific quantitative PCR was used to assess telomere length in two groups of women with evidence of reproductive aging: (i) patients with idiop...
متن کاملTelomere Length Shortens with Body Length in Alligator mississippiensis
In Alligator mississippiensis (American Alligator), body length increases with age, but body length can be used as an accurate estimator of age only up to about 6–7 years, when growth rates slow considerably. Telomeres are repetitive DNA sequences that cap the ends of each chromosome. Telomeres shorten with age in most animals, but telomere shortening has not been examined in reptiles. We measu...
