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,

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,

Telomeres protect genomic stability and shortening is one of the hallmarks of ageing. Telomerase reverse transcriptase (TERT) is the major protein component of telomerase, which elongates telomeres.

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 ...

A mutation in a functional Sp1 binding site of the telomerase RNA gene (hTERC) promoter in a patient with Paroxysmal Nocturnal Haemoglobinuria [PDF]
Background<br/><br/> Mutations in the gene coding for the RNA component of telomerase, hTERC, have been found in autosomal dominant dyskeratosis congenita (DC) and aplastic anemia.

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 ...

Telomerase RNA function in recombinant Tetrahymena telomerase [PDF]
Telomerase is a ribonucleoprotein reverse transcriptase specialized for use of a sequence within its integral RNA component as the template for DNA synthesis. Telomerase adds telomeric simple sequence repeats to single-stranded primers in vitro or chromosome ends in vivo.

A telomerase holoenzyme protein enhances telomerase RNA assembly with telomerase reverse transcriptase [PDF]
Telomerase maintains the simple sequence repeats at chromosome ends, protecting cells from genomic rearrangement, proliferative senescence and death. The telomerase reverse transcriptase (TERT) and telomerase RNA (TER) alone can assemble into active enzyme in a heterologous cell extract, but the physiological process of telomerase biogenesis is more ...

MDM2 negatively regulates the human telomerase RNA gene promoter [PDF]
<b>Background:</b> We have previously demonstrated that NF-Y and Sp1 interact with the human telomerase RNA (hTR) promoter and play a central role in its regulation. We have also shown that pRB activates the hTR promoter, but the mechanism

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 ...
