July Longevity Update

Hello and welcome once again to this month’s longevity update. I’ve just had the busiest summer ever teaching-wise. So busy, that I couldn’t even follow the latest longevity developments. Therefore it was quite novel, when I sat down to compile this update, to have almost no idea what transpired during July. Needless to say, a lot did, including a result I’ve been waiting for since David Sinclair sent some cryptic tweets last summer.

As mentioned in the last update, I volunteered at Ending Age-Related Diseases in New York, which was the highlight of my summer. It wasn’t so much finding out the latest news which made it great; it was the feeling of participation and meeting so many wonderful people. After having spent so much time communicating with other enthusiasts only via computer, it was refreshing to finally be surrounded by like-minded people. I highly recommend attending next year’s conference, or any other longevity related conference – a list of which can be found here. If you’re curious to read more about it, here’s the official write up & the view from Fight Aging!

Follow me on Twitter @ChrisPollyanna1 for the latest updates! (after a two month hiatus… )

Finally, any feedback is greatly appreciated… J

NOTE: I’ve been having trouble linking to the science journal hacking site www.sci-hub.tw , so am only including Full Text links to articles not behind a paywall. I have still been able to download most of them, so if there are any that you are after, I can send them upon request, or you can simply copy the paper’s URL into the site above to get +95% of papers hidden behind paywalls.

July Round-Up:

The cryptic tweets mentioned were about the promise of cellular reprogramming, whereby the age of a cell gets reverted back to youthfulness by the introduction of genetic factors. I strongly believe that this area is going to explode in the next few years and is the closest thing we have to a “silver bullet” against ageing. In the present study, which has not been peer reviewed yet, they were able to re-grow the optic nerve of mice – something hitherto impossible: Reversal of ageing- and injury-induced vision loss by Tet-dependent epigenetic reprogramming

An interesting study where they took a gene associated with longevity among centenarians and gave it to a group of mice. This resulted in the mice having a reduction in the hardening of their arteries: Single systemic transfer of a human gene associated with exceptional longevity halts the progression of atherosclerosis and inflammation in ApoE knockout mice through a CXCR4-mediated mechanism.

Telomeres, the protective caps at the end of our chromosomes, have been the subject of intense debate in the ageing community: is their length and reduction over time a symptom or a cause of ageing? So far the results have been inconclusive, but the following animal comparative study sheds some new light. It turns out that it is not the length of the telomere which predicts a species lifespan, it is the rate of shortening (of course this doesn’t tell us about cause and effect): Telomere shortening rate predicts species life span. Full Text LEAF Summary & an interview with the author, who was a headline speaker at the conference.

It’s been just over 30 years since the modern field of ageing research started and the following review, from the leading lights of the field, provides an overview of the progress made so far, as well as arguing that we have now reached an inflection point whereby we can start to translate our understanding into treatments to increase human healthspan: From discoveries in ageing research to therapeutics for healthy ageing

And finally, two articles about my favourite available longevity drug: Rapamycin. OK, the first article is not about Rapamycin – it’s about a similar drug, working on the same pathway, which is currently in human clinical trials. Rapamycin is now off-patent, so pharma can’t make big bucks off it, however, with this “new” drug, they can charge whatever they want! It is still significant though, for if it gains approval in a couple of years, it will be the first true anti-ageing drug on the market: Can a Single Pill Keep You Healthy to 100? For those unwilling to wait a few years to be charged an exorbitant fee, there is always generic Rapamycin, and the second article is about the men (the article is from Men’sHealth), who like me, have followed this second path: This Obscure, Potentially Dangerous Drug Could Stop Aging This is a surprisingly excellent article, featuring the same doctor I got a prescription from, as well as an honest assessment of the potential drawbacks and benefits.

July Supplemental Information

***Disclaimer 1 – As should be self-evident to anyone receiving these emails, I am NOT a doctor or indeed a scientist. All the information pertained within is for information purposes only; use at your own risk. Please consult with a healthcare practitioner if needing medical advice.***

**Disclaimer 2 – In no way should supplements be a replacement for an unhealthy diet or lifestyle. A varied, plant dominant dietary pattern is the cornerstone for health. Try to eat the rainbow – the greater the variety, the greater the benefit. Even though I might take a supplement derived from a plant source, I still eat the plant in question. Also, make sure you move as much as possible – that is what we evolved to do.**

*Also bear in mind that most of the studies mentioned below are in rodents, not humans. Rodents, needless to say, do not always react the same way to drugs as humans do – witness the countless times cancer or another disease has been cured in rodents only to subsequently fail human trials. I have *bolded any human trials.*
