A failure to communicate

December 23, 2013

Here’s some interesting news from Australia (with an interesting analogy for bad communications). I assume "late next year" refers to late 2014.

The potential fall-out from this one boggles the mind.

Cause of ageing that can be reversed
19 December 2013

Medical researchers have found a cause of ageing in animals that can be reversed, possibly paving the way for new treatments for age-related diseases including cancer, type 2 diabetes, muscle wasting and inflammatory diseases.

The researchers hope to start human trials late next year.

The study, published today in the journal Cell, relates to mitochondria – our cells’ battery packs – which provide energy to carry out key biological functions.

The work, led by David Sinclair from UNSW Medicine, found a series of molecular events enable communication inside cells between the mitochondria and the nucleus. As communication breaks down, ageing accelerates.

“The ageing process we discovered is like a married couple – when they are young, they communicate well, but over time, living in close quarters for many years, communication breaks down,” says UNSW Professor Sinclair, who is based at Harvard Medical School.

“And just like a couple, restoring communication solved the problem,” says the geneticist.
