Ageing is an inexorable homeostatic failure of largely unknown aetiology that leads to increased vulnerability to disease limiting the quality of life in the elderly and creating high costs to the society. Until recently, the daunting complexity of the ageing process, the conspicuous lack of tools to study it, and a dearth of experimentally tractable model systems have greatly hindered any hypothe ...

Telomeres are DNA-nucleoprotein structures that protect the ends of human chromosomes through the formation of a ‘cap’ that prevents exonucleolytic degradation, inter- & intra-chromosomal fusion and subsequent chromosomal instability. Telomerase, the ribonucleoprotein enzyme that maintains linear chromosomal DNA ends by the addition of TTAGGG repeats, is completely repressed or present only at low ...
