May 2020 Longevity Review

Hello and welcome again to this month’s longevity review. May turned out to be a bumper month in longevity research news, led off by a preprint study which caused quite a buzz in the community and which was previewed on these very pages last year. That study concerned adding youthful blood factors to rats which resulted in a 54% epigenetic age reversal! It was complemented by another which diluted harmful factors in old blood, as well as a new senolytic method, and some gene & stem cell therapy results - check out the round-up section for further details.

 

The big news from me is that the program for Ending Age Related Disease 2020 has been released, and what a stellar lineup it is! It is a veritable who’s who of the longevity research community. If you’ve never attended a longevity conference before, this is the perfect opportunity to break your duck, as not only can you do so from the comfort of your home, but it is also eminently affordable. In fact, there is even a free option, which gives you access to the keynote speeches as well as a biotech startup seminar hosted by Ichor’s Kelsey Moody. I will once again be volunteering at this conference.
Follow me on Twitter @ChrisPollyanna1 for the latest news.
It would also be great if you joined my longevity Facebook group.
Finally – please share your thoughts and feedback in the comments section at the bottom.

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 still have 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.
May Round-Up:

  • I’m usually reticent in publishing details of studies which have not been peer reviewed; however, sometimes the results are so potentially groundbreaking that I can’t hold back. This study falls into that category. Here, an undisclosed plasma fraction was used to reverse the age of rats back to a youthful level. I initially disclosed parts of this study in my February 2019 Review, where various biomarkers, such as those for inflammation, returned to the levels of younger rats. This new extension took things a step further by checking the epigenetic age of the rats in various tissues after treatment, which resulted in an average age reduction of 54%. Extraordinary.

And especially due to the extraordinary nature of these results, I need to add a few caveats. Firstly, as mentioned before, it has now yet been peer reviewed. Secondly, it used an extremely small cohort of rats (6). Thirdly, a lifespan study has not yet been completed. However, the fact that Steve Horvath, who is the leader in epigenetic age testing, is a co-author lends a considerable amount of credence to the results. My fingers are definitely crossed on this one!

Very positive interpretation from Josh Mittledorf: Age Reduction Breakthrough

LEAF Journal Club video on the study

  • Almost the reverse of the above study is the one below from the Conboys, who believe that factors in old blood can overpower any benefits from youthful factors. Here they simply diluted old blood by replacing 50% of it with saline and albumin (5%) which resulted in some rejuvenation. If this holds water, it would be easily translatable to humans as plasma exchange is an established medical procedure.

Josh Mittledorf’s take: Out With the Old Blood

  • It is my opinion that a combination of the two approaches is most likely to work best, but of course that experiment still needs to be done before reaching any conclusions. For more studies of this ilk, check out the Young Blood Factors section in the Supplemental Information below.
  • In this study gene editing was used to improve muscle wasting, a serious problem for the elderly, in mice by targeting myostatin.

  • Finally, stem cells were used to repair ageing bone marrow and thereby aslo increase its antioxidant capacity and improve immune function.

2020 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.*

Non-prescription Supplements (in alphabetical order)
*Due to concerns about engendering homeostasis, I’ve begun varying my intake of supplements so that I’m not taking all of them every day. Haven’t worked out a rota so far.
Astaxanthin – which is behind the pink colour of salmon & shrimp. Considered the most powerful carotinoid, it has anti-oxidative, anti-inflamatory, anti-cancer, neuro-protective and skin-protective qualities. I take 4 or 8 mg intermittently.

Curcumin – the spice which gives curries their yellow colour. Anti-inflammatory and neuroprotective. I take 1 gram intermittently. Needs to be taken with black pepper (piperine) to improve bio-availability.

Melatonin – a natural hormone produced in the pineal gland, it makes us get to sleep every night, but it has many other functions, including as a mitochondrial anti-oxidant. I’ve been taking 3mg for years before bed time purely as a sleep aid, but I’ve recently noticed it repeatedly cropping up in my longevity searches so decided to include it in its own section.

Young Blood Factors or other heterochronic transplantation another potential “silver bullet” against ageing based on the discovery that young blood seems to rejuvenate older animals and vice versa.
