  • Telomeres and ageing. .
.
Telomeres are the "caps" at the ends of eukaryotic chromosomes (shown in green). These hexanucleotide repeats run for an average 5 - 15 kb in humans and play a crucial role in genome stability.  Yet these protective repeats shorten with each somatic cell division, and this is one of the leading hypotheses as to why we age. .
.
One of the most striking pieces of evidence for telomeric length and ageing is that mutations in genes responsible for telomere maintenance or telomerase lead to disorders that display an onset of premature ageing symptoms, like Progeria, and these individuals have much shorter lifespans than those unaffected by these mutations.  Telomeric shortening can have both positive and negative effects:  cancer cell proliferation can be halted due to a breakdown in telomeres, however most phenotypic displays of ageing, eg. collagen loss in tissue, is also a result of shortening telomeres. .
.
Interestingly, the standard lab mouse isn't a great model for studying telomeres and ageing: mice have telomere lengths several times that of what humans have, and their average lifespan ends before any critical telomere shortening is observed. Additionally, telomerase knockout mice are fine for several generations before issues emerge.  Thus, the vertebrate model organism for telomeric length and ageing is actually the zebrafish, whose telomere length matches our own (5 - 15kb) and whose telomerase protein shares a number of conserved structural motifs with that in humans. .
.
Though therapeutics have yet to emerge for halting or reversing telomere shortening, we do know a number of things that contribute to the speed at which they shorten, such as UV radiation, stress, tissue damage, etc.  So sunscreen and meditation may hold some effect over the ageing process! .

  • My few pics from my very busy day....
Picking flowers with the princess, snuggles with the little man, OT with Will, and Coopers “fat Christmas tree” (as he described it) potato head playdough person. Lots of fun

1. Pretending I have a life
2. Going to bed at 9pm
3. Seeing how much I can procrastinate and still pass my exams
