@@Freja_Solstheim Evolution is about keeping the species alive, not the individual and the main survival strategies are genetic variation and alliances between species.

Just wanted to say thanks for making these amazing videos. The longevity movement is lucky to have you on its side. I'm not sure if you saw the in vitro study of telomerase-inducing compounds, but a blend of Astragalus, Rhodiola rosea, broccoli seed extract, and vitamin D was significantly more powerful than TA-65 at increasing telomerase.
Been subscribed to your channel for some weeks. The quality and delivery of content is top notch. I am not of Molecular Biology background but interested in it since I age. The genome is a latent space representation from my perspective and might help in gaining some insights without doing actual experiments that take time.
This understanding is the key to the real fountain of youth. We're on the verge of something very cool in the human species. We need make some real big cultural adjustments very soon, because it's about to get real-real.
Chinese Astragalus (cheap)is where they get (expensive) TA-65, and the Astragalus works better. The peptide Epitalon, also under the name Epithalon lengthens Telomeres. 5 to 10 mg/day for 10 to 14 days typically once a year.
I really love your videos and your deep exploration into these aging and health related discussions! Also, I like your accent as you are a joy to listen to! Thank you!
11:00 Would you be able to make a type of telomerase that can spot the difference between healthy cells and cancer cells? Maybe do this via the therapy delivery mechanism?
Melatonin can reverse Thymus shrinking in mice. It also appears to inhibit prostate tissue growth in rats. Humans have age related drastic decline in melatonin production(which some call melatonin the clock of aging, or the conductor of the body's hormonal orchestra), this might have something to do with both thymic shrinking and prostate enlargement issues which eventually become common amongst most men at latter ages.
good overview. small glitch: the hyflick limit is oudated... it was deteremined only in one or 2 cell types, in vitro. On the level of tissues it is much higher and different tissues have a very different limit. Skin cells replicate much more often
I dont believe telomerase activity will stimulate cancer growth and there is no causal evidence support this fear. Cancers have unregulated cell growth, and this growth requires telomerase activity. However, supporting telomerase activity has no effect on stimulating unregulated cell growth(as far as we know and there is no reason to believe otherwise, although of course anything is possible). Telomerase activity is used by cancers yes, but if you give a healthy cell with regulated cell growth telomerase, this wont suddenly trigger aberrant activation of the cell cycle, it will simply allow the cell grow uncontrollably if it already has the genetic mutations necessary for uncontrolled cell growth. Honestly, it probably is pushing a dysfunctional cell one step closer to being immortal and this is a concern and the transient idea is interesting and theoretically abrupt supplementation to TA65 should seize growth. This was a well designed video great data.. personally I feel comfortable taking TA-65 but perhaps you're right to heavily weigh safety when there are so many unknowns
Thank you for the information. I'm writing a research proposal on telomere shortening. If u got any sources or researches i should study that can help me plz let me know. Thanks again.
Dr. Cooke's mRNA work is incredible. "Dr. John P. Cooke is the Chair of the Department of Cardiovascular Sciences at the Houston Methodist Research Institute, Director of the Center for Cardiovascular Regeneration, and Medical Director of the RNA Therapeutics Program in the Houston Methodist DeBakey Heart and Vascular Center in Houston, Texas."
Couldn't really find much recent data on it which makes me question the approach, so basically dont think there is enough data for me to have any opinions
First time hearing this compound, did some brief research; People on Reddit are saying it slightly darkens their hair color and has noticeable improvements on their skin and makes them have vivid dreams and be more energetic overall (All these are anectodal tho) A quick search on PubMed yields some results but almost all of them are kinda outdated: pubmed.ncbi.nlm.nih.gov/?term=epitalon
This was fantastic. I'm so glad you went into more of a deep dive than most other videos on this topic. I'm super curious about your thoughts on this so called "WILT 2.0" as Aubrey De Grey calls it (From MAIA Biotechnology). Conceptually it sounds like a molecule that kills any cells that begin to express telomerase. I've never heard anything like it before (Not sure how promising or dangerous that could be).
@@TheSheekeyScienceShow Check out the video with Aubrey De Grey and Richard heart (Streamed live on May 11 2021). He talks about it for a few minutes. It has its own youtube video chapter so you can skip to it.
I count myself lucky for not getting cancer from taking TA-65 5 years ago. It was cool seeing the results of my telomere tests though. I'll be a guinea pig for anything promising haha.
Your videos are always interesting with lots of content. After viewing this video my question is; what will you personally do to maximize the current available to extent your longevity? Thanks!
Well thank you very much! This really helps fill in a lot of mechanistic details I didn't know about. I wonder what you would think of the potential of the many additional dietary agents beyond TA-65 and Danazol showing telomerase activating effects, with even some of these, albeit a limited number, having clinical studies showing a telomere lengthening effect? Some are the nutrients/bioactives such as vitamin D, tocotrienols, beta carotene, silymarin, triterpenes, and other flavonoids (luteolin, apigenin, puerarin).
From what I have seen so far, very little Gotu Kola (extract from 750mg of fresh plant, its substances have a very long half life and accumulate in the body), polysaccharides of Astragalus (Astragaloside IV shortens the, 50% polysaccharides + 5% Astragaloside IV extract was useless, so watch out for 70% polysaccharides extract), the expensive TA-65 and AC-11, coq10 + selenium and walnuts seem to lengthen telomeres or stop the shortening in actual humans and not just cells and mice.
I would like to see a podcast on Carbon 60. Increased lab rat lifespan by 90%. Been using it for 3 years in October. Plan to have a telomere blood test then.
So many unknowns, yet just look how much we know compared to 1990's. Now imagine 2050's, (Accounting for the ever-accelerating rate of technological progress over time) we will learn and uncover things we didn't know existed even more so than we have in the last 30 years and then will come 2080's and so on.. I'm really hopeful for the future and hope that everyone watching this video will get to be cured of this ultimate disease :D
Telomeres can't be everything about age. Why do the telomere length of some parents match that of their kids but you can still easily tell who is the parent and who is the child by appearance?
Are you sure you aren't mixing up telomeres with chromosomes? Is there a study showing that kids have telomere lengths matching that of their parents? The parents telomeres should be much shorter due to cell divisions over the years that would shorten the telomere length with each subsequent division. Chromosome are what determine appearance and telomeres are not part of that except in a very indirect way.
I agree in that I believe diet and supplements are only part of the anti-aging puzzle. Breathing,sleep, meditation, and activating various states of consciousness are probably more important.
Nice video. Pls take some drawing courses for digital art(with graphic tablet + krita/photoshop), I feel big potential, in 5 years you will be able to draw some awesome cell structures!!
There is a video with 83 year old doctor claiming he increased his telomeres length by 100%: ua-cam.com/video/sMtC40HAeoY/v-deo.html What do you think about it? It lacks specific information about this test, like the exact model of the chamber, pressure, duration of the sessions, percentage of oxygen, etc. I am pretty sure you won't get the same results in inflatable chambers and perhaps some of the health clinic chamber models. It would be nice to know if this is repeatable, so let's say you your 60 sessions and get X % of telomere length increase. You wait couple of years and do another set of 60 sessions. Would you get the same result? Would it be a bit less? Would it be a lot less or is this just one off effect which is not repeatable? Also is there any research with younger people? I would assume you won't get 100% increase in length, but would it be the same in absolute increase or maybe even better? Is there a risk of getting cancer through this therapy?
I think there is much still to learn about telomeres but I hope this video has given a good overview of our current understanding. p.s who doesn't love the shelterin complex!? :D

Ta65 works? I’m gonna get some for me and my mom
@@DriverJ-N It lengthens telomeres, but whether that's good or bad remains to be seen. Could just make it easier to get cancer for all we know.
@@blakemorgan8450 This is simplified view on this subject.
I am dubious about this comment and TA-65 ability to extend telomeres length.
@@Chris-kr7gg Hi Craig, I can show you photos of the test results if you'd like.
QQQ...are the telomeres at the end of the entire DNA strand or at the end of the Chromosomes?
So there isnt just one long DNA strand, but several. Each strand has telomeres at either end in human cells
Your videos are always interesting with lots of content. After viewing this video my question is; what will you personally do to maximize the current available to extent your longevity? Thanks!
