The fight against aging that might soon be a rout

- LISA TAMATI

As another year has just rolled over and I quickly approach the half century mark in my life, (my God, how did that happen?) I have to admit to a growing desire to do everything I can to slow the clock down and to stop the dreaded decline of old age. For both myself and my ageing loved ones.

I am constantly on the look out for the latest in anti-ageing breakthrou­ghs and technologi­es. It’s something that preoccupie­s many of us in our quest to live long, healthy, strong lives.

But what if I told you that scientists have now got the power to stop time or even to reverse the ageing process. Would you think that is just science fiction? The fountain of youth doesn’t exist, well listen up.

Recently I had the privilege of having the world’s leading scientist on anti-ageing, Nobel Prize winner and American Inventor of the year, Dr Bill Andrews on my podcast ‘‘Pushing the Limits’’.

Dr Bill is credited with the discovery of the human telomerase gene. He is a molecular biologist and gerontolog­ist who has spent his entire career trying to stop the ageing process by lengthenin­g telomeres, which will in effect stop the clock and give us many many more years of healthy life without the decline usually associated with ageing.

He is the founder of a bio tech company called Sierra Sciences and he and his team have tested more than 500,000 compounds in a search for a molecule that will turn on the telomerase gene and stop the shortening, or even lengthen telomeres. He has found over 900.

So what are telomeres and why do they matter in regards ageing? In the 1940’s scientists discovered telomeres, which are the caps at the end of the each strand of DNA and these ‘‘caps’’ protect our chromosome­s, a bit like the plastic at the end of a shoelace.

Without the plastic tips our shoes laces become frayed and can no longer do their job and the same happens with telomeres.

When we are born our telomeres are around 10,000 bases in length (a unit used to measure chromosome­s) but each time a cell replicates itself (which they are doing constantly throughout life) the telomeres shorten, a little bit is lost of that plastic tip, if you like.

When the telomeres reach 5000 bases in length the DNA of the cell starts to unravel and the cell is unable to reproduce itself and it dies. Short telomeres means a short life expectancy.

However, our reproducti­ve cells do not have this problem.

They don’t age because the telomerase gene is turned on in these cells. Hence a baby is born with full length telomeres, even if the mother was 20, 30 or 40 years old.

The rest of the cells in the body however don’t have this telomerase gene.

Dr Bill and his team now have more than 900 of compounds that can turn this gene on to some degree and can stop or slow down the ageing process.

Their first compound to market is known as TAM818 and this has been licensed by four companies.

The products currently on the market, Dr Andrews says, are about 1/6th of the potency needed to actually make an 80-year-old back into a 20-year-old but they definitely slow the process of ageing down.

However, Dr Andrews now has compounds that are 30 fold

For one patient it costs around $5 million, so it's only for the super rich at this stage.

stronger than what is required to reverse the ageing process and this has been licensed to La Bella Gene therapeuti­cs, who are due to start clinical trials on humans in early 2018.

Currently the only fly in the ointment are the costs for this treatment, which are astronomic­al.

For one patient it costs around $5 million, so it’s only for the super rich at this stage.

But if the trials are successful this will be the start of a very different future for the human race.

In previous studies done at Harvard University on rats they have been able to turn aged rats in to young rats again.

All the signs and symptoms of ageing reversed and they are able, in the lab, to take old skin cells and turn them into baby skin cells and keep them alive indefinite­ly.

They actually called these cells immortal.

They don’t die or deteriorat­e at all.
