Mice with hyper-long telomeres show less metabolic aging and longer lifespans
Telomere shortening is associated with aging. Here the authors analyze mice with hyperlong telomeres and demonstrate that longer telomeres than normal have beneficial effects such as delayed metabolic aging, increased longevity and less incidence of ...

Telomeres, the protective ends of linear chromosomes, shorten throughout an individual’s lifetime. Telomere shortening is a hallmark of molecular aging and is associated with premature appearance of diseases associated with aging.

Multiple cancer pathways regulate telomere protection
Telomeres are considered as universal anti‐cancer targets, as telomere maintenance is essential to sustain indefinite cancer growth. Mutations in telomerase, the enzyme that maintains telomeres, are among the most frequently found in cancer. In addition,

Telomeric RNAs are essential to maintain telomeres
The telomeric long-non coding RNA, TERRA, has been proposed in the past to modulate different telomeric functions based on in vitrostudies. Here the authors show, using a genetic deletion approach, that TERRA is transcribed from the 20q subtelomere and ...

Telomerase Is Processive [PDF]
Telomerase synthesizes tandem repeats of the sequence d(TTGGGG) onto input d(TTGGGG)n primer oligonucleotides (C. W. Greider and E. H. Blackburn, Cell 43:405-413). An intrinsic RNA component of the enzyme provides the template for d(TTGGGG)n repeat synthesis [C. W. Greider and E. H. Blackburn, Nature (London) 337:331-337, 1989; G.-L. Lu, J. D. Bradley,

Aplastic anemia is a rare but life-threatening disorder characterized by cytopenia in at least two of the three blood lineages. A frequent feature of patients with aplastic anemia is that they have shorter telomeres than those of age-matched controls ...

The Unmasking of Telomerase [PDF]
Telomerase is a ribonucleoprotein complex that reverse transcribes a portion of its RNA subunit during the synthesis of G-rich DNA at the 3' end of each chromosome in most eukaryotes. This activity compensates for the inability of the normal DNA replication machinery to fully replicate chromosome termini. The roles of telomerase in cellular immortality

The Rate of Increase of Short Telomeres Predicts Longevity in Mammals
Aberrantly short telomeres result in decreased longevity in both humans and mice with defective telomere maintenance. Normal populations of humans and mice present high interindividual variation in telomere length, but it is unknown whether this is ...

Telomerase, a eukaryotic ribonucleoprotein (RNP) complex, contains both an essential RNA and a protein reverse transcriptase subunit. By reverse transcription, the telomerase RNP maintains telomere length stability in almost all cancer cells. Over the past few years there has been significant progress in identifying the components of the telomerase ...

Summary: Telomeres are considered potential anti-cancer targets. Most studies have focused on telomerase inhibition, but this strategy has largely failed in clinical trials.
