Sirtuins are highly conserved proteins that are involved in a variety of important cellular processes such as DNA repair, metabolism and circadian rhythms. The mammalian sirtuins (SIRT1-7) are a family of proteins that carry out NAD+-dependent protein deacylation and mono-ADP-ribosylation. These modifications on proteins can influence their stability, localisation within a cell and activity.
In the late 90s interest in sirtuins bloomed as it was found yeast lived 30% longer when they had an additional copy of a yeast sirtuin, Sir2. Similar studies have now been performed in mice, but whilst overexpression of SIRT1 in mice does not result in lifespan extension, overexpression of SIRT6 does. This has led to SIRT6 being referred to as the longevity sirtuin. However, there seems to be some sex- and mouse strain-dependent differences. So, in the remainder of the video, we will discuss what you need to know about SIRT6 including it's proposed cellular activities, it's association with longevity and how SIRT6 activation using allosteric activators could have future therapeutic potential.

So is SIRT6 my new favourite protein? Hmmm, of course not, p53 all the way, but it's up there, maybe top 10 :D

Awesome video as always! I’m currently taking fucoidan, quercetin, and fisetin daily because I think there’s good evidence these molecules extend healthy human lifespan at proper doses and it turns out there’s pretty good evidence that all 3 may be SIRT6 activators which would partially explain why they can extend healthy human lifespan.

Another great video. If you take a Sirt6 activator, is it essential that your NAD+ levels are at a 'healthy' level to make the effort worthwhile?

This was an excellent video and very much appreciated! Thanks!
Would you say Sirt6 is a senolytic or is Sirt6 under expression a marker of cellular senescence?

Have you thought about looking at bloodresult variations and aging? E.g markers of inflammation, blood urea, WBC, RBC etc and their changes over time. How they indicate internal aging and what we can do about it?

The difference between the lifespan extension in male and female mice study, indicates that lifespan increase may have been caused by igf1 reduction instead of sirtuin-6 itself.

Since DR (or CR) are said to function by activating Sirtuin genes, does that mean that female test subjects respond less to DR than males?
Also, at the present time, is it believed that resveratrol has any health benefits at all?

In being tied to CR, I wonder how IF (including in different patterns / durations) would affect SIRT6 activation.... possibly coupled with various 'supplements' (e.g. NAD precursors). How easy is it to measure levels of SIRT6?

What's the story with fucoidan as a sirt 6 activator?

Is it possible to activate fisetin, quercetin and fucoiden with piperine like resveratrol supposedly is? Are there any other activators you would recommend to increase the efficacy and bio availability of these supplements? Thanks!

You can activate sirtuin 6 with cyanidin which is found in red cabbage and cherries.

Question: Being from mixed parents...could one parents genes be latent and could NMN bring them out of latency? I'm asking because of incredible results I'm getting nfrom NMN incuding white hair regaining colour which starts off the same colour as my mums hair, hazel, where mine was always really dark brown.

I have wondered about something for a long time - - butyrate is a general HDAC inhibitor; sirtuins are HDACs. What's up with that?

Why haven't researchers done an in-vivo, randomized, placebo controlled study of fucoidan plus an NAD precursor looking at synergistic longevity benefits?

I would suggest giving more credit to the lab groups, authors, institutions, and journals. These studies are often progressions of earlier studies by the same labs and principal researchers and not one off studies. It's not that hard to give credit where it's due.
