Telomere shortening has been linked to some aspects of organismal ageing. Here the authors create chimaeric mice that contain a mix of cells with normal or unnaturally long telomeres, and show chimaeric mice are protected from some forms of ageing ...

The pif1 helicase, a negative regulator of telomerase, acts preferentially at long telomeres. [PDF]
Telomerase, the enzyme that maintains telomeres, preferentially lengthens short telomeres. The S. cerevisiae Pif1 DNA helicase inhibits both telomerase-mediated telomere lengthening and de novo telomere addition at double strand breaks (DSB).

XPF activates break-induced telomere synthesis
Here the authors show TERRA R-loops recruit the endonuclease XPF to telomeres, leading to DNA double-strand breaks to activate break-induced telomere synthesis at telomeres that utilize the alternative lengthening of telomeres (ALT) pathway to extend ...

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 ...

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,

A major goal in aging research is to improve health during aging. In the case of mice, genetic manipulations that shorten or lengthen telomeres result, respectively, in decreased or increased longevity.

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 ...

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 ...

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