Telomeres – Too much of a good thing?
- serg_chernata 10y agoThis is an interesting subject. I first heard of Telomeres from Dr. Rhonda Patrick[1]. She has her own podcast and actively visits podcasts of other hosts to talk about health and longevity. For anyone interested, link below. I've gotten flack for mentioning Joe Rogan podcast here before, but I discovered Dr. Patrick through Joe's podcast and her visits are some of my favorites.

- erichmond 10y agoWow, why did you catch flack for mentioning the JRE?

- withdavidli 10y agosomewhat understandable why people have this view of him and his show. he let's his guests go on about what they think. it's usually a 3hr show. this gives people the perception that he believes in whatever they're saying because he doesn't interrupt his guests all the time. imo Joe is very open minded, an avg Joe (had to) that is willing to hear people out and is fair handed in contrasting opinions. listening to the one with him, hannibal burris, and sam harris shows that he tries to take emotion out of argument and see where each person is coming from. but other times he'll just repeat things what he has heard other guests has said. for instance drugs that clogs up the blood for bicyclists when he had lance armstrong on. i wouldn't say his show is scientifically dense though. that really depends on the guest. so when you have a person like rhonda on, yea her field is science and it's going to be dense in that subject matter.
- sigmar 10y agoIsn't giving over airtime on your own show somewhat an endorsement? If you're giving them free advertising, you should probably at least spend some time vetting their credibility. Seems irresponsible to give a platform to moon landing truthers.
- colordrops 10y agoMoon landing truthers get pretty much almost no time with anyone of consequence, so they are already well black listed. Rogan at least lets you see what is inside of the minds of these people, which is fascinating in itself. No subject, no matter how distasteful or apparently false, should be completely eradicated from the human dialog, even if only to reconfirm your distaste for it.
- melloclello 10y agoI kinda have a soft spot for ol' Joe Rogan and I see him hosting moon landing theorists on his show as not unlike Louis Theroux doing a show about UFO nuts. Interestingly enough Rogan did have Theroux on his show once, I was hoping it would be a good interview but it went really badly.
- superbaconman 10y agoWell every major and minor news source in the US gave air time to a climate change denier, birther, and vaccination sceptic. I mean in the grand scheme of things, the JRE is nothing and IMO some of these guests put forth great ideas I would have never considered. Speaking to this article, I'd be interested to hear if any research has explicitly set out to verify the "long telomeres cause cancer" claim.
- busterarm 10y agoOh hey, I remember that thread! I was supportive, at least.
- cyphreak 10y agoHN (l)users typically veer to the ctrl-left. Rational thought threatens their narratives.
- glibgil 10y agoJamie, see if you can pull that up
- PerfectElement 10y agoI could never get into it because of his personal beef against veganism (no pun intended). I think it started when the guys who made Cowspiracy went to his show. After that he went on a mission to find every piece of pseudoscience or blog post that said the animal industry is actually good for the environment, or that plants have feelings, or that vegans were unhealthy, and then went on a Twitter rage against vegans. It was pretty clear that his open-mindedness was quite limited. The sad thing is that a lot of people think he is a reliable source of information.
- metamet 10y agoOne thing to remember about Joe's perspective on veganism is that he is a hunter and public figure, so he has attracted attention from militant vegans. While he has vegan friends and doesn't seem to really care what people eat, he's vocal with his annoyance with that particular subset. Plus he's a comedian, so you can't take anything he says personally. On a side note, I'm still waiting to hear some hard science on the affects veganism (which clearly doesn't include The China Study). If the right person were out there, I'd be curious to hear them on JRE.
- ievahanordah 10y agoThey were wrong about the telomeres? What hasn't been proven wrong at sometime, anything?
- UhUhUhUh 10y agoInteresting how entities initially considered more or less as packaging stuff without much use, such as histones and telomeres, turn out to be a lot more than that. People, and investors, may tend to focus on the obviously active part of the code and to overlook the architecture.
- FullMtlAlcoholc 10y agoLike how thr non-coding regions of the genome were termed junk DNA
- fabian2k 10y agoThe term junk DNA is mostly used in popular science media, not by scientists themselves. It was pretty obvious early that some noncoding regions did do something and weren't just junk, but somehow the term still survived.
- dekhn 10y agoLots of scientists use the term junk DNA. I've worked in and around sequencing for 20+ years now and the term in common in arguments about what the function of non-coding regions is.
- knicholes 10y agoIn my introduction to biology class at UVU in 2004 they taught us "junk DNA."
- blisterpeanuts 10y agoMy bio course taught the terms introns and exons. Exons are the portions of DNA that are used to express proteins. Introns correspond to "junk DNA" and are removed prior to protein expression. Their function is not fully understood.

- daemonk 10y agoTert has been shown to have non-canonical functions interacting with signaling pathways (wnt and nf-kb). It's easy to think of genes as a single function entity when the truth is a lot of genes have pleiotropic effects. The same can probably be said for other genes involved in telomere maintenance. It's probably more complicated than a simple correlation between length of telomere and resulting phenotype.
- atomical 10y agoLiz Parrish had some cutting edge genetic therapy done to increase her telomeres. https://www.reddit.com/r/Futurology/comments/3ocsbi/ama_my_name_is_liz_parrish_ceo_of_bioviva_the/ https://www.reddit.com/r/Futurology/comments/3ocsbi/ama_my_n...
- imaginenore 10y agoWe don't know how it will end up for her. She might live past 150, or she might get horrible cancers all over her body in 5 years. We also don't know if she actually had undergone the treatment, it can simply be a scam.
- atomical 10y agoTruly, anything can be a scam. I think the most disappointing outcome for her will be if she lives out the rest of her life in an average way. Did it work? Didn't it work? Sure, living past 90 would be nice but did her treatment have anything to do with it if that's the case? There are some things we won't know in our lifetimes.
- tormeh 10y agoIf it worked I would expect her to start looking younger in some way.
- industriousthou 10y agoI believe increasing telomere length may slow ageing, but wouldn't reverse it.
- andygates 10y agoI'm moderately impressed that she hasn't already eruputed into a tumour monster.
- sytelus 10y agoIt's been a year and so far no success... while unfortunately we have not yet succeeded in undoing all aspects of aging just yet, we have gathered tantalizing human data for the first time in history http://bioviva-science.com/blog/one-year-anniversary-of-biovivas-gene-therapy-against-human-aging http://bioviva-science.com/blog/one-year-anniversary-of-biov...
- badloginagain 10y agoThis is a really well written article. I knew nothing about telomars, their importance in the field, nor the controversy surrounding their length. While some of it was over my head (specifically that image of telomar transformation(?)), the author did a fantastic job of giving an overview of the field, create a compelling argument (at least to a layman), all with several links that (I hope) support and cite his arguments. Good lessons in persuasive writing here.
- reasonattlm 10y agoOne thing to bear in mind is that most of the relevant studies are carried out in mice, and mouse telomere dynamics are significantly different from those of humans. Telomerase gene therapies clearly slow aging and extend life in mice to some degree, but the actual mechanism involved is up for debate. We can argue that it has more to do with stem cell activity and influence on mitochondrial function for example than keeping cells out of senescence. My comfort level for telomerase therapies would be increased by running them in dogs or another longer lived mammal with telomere dynamics that are closer to those of humans and observing the results there. Of course this might well be beaten out by actually running them in humans if the BioViva / Sierra Sciences collaboration gets their medical center running in Fiji to offer the gene therapy at a reasonable cost some time in the next year or two.
- cantrevealname 10y agoThe first time I heard about telomeres many years ago, it blew my mind. What everyone has thought of, but no scientist is willing to say out loud is that maybe if the telomere count is reset (like it is for babies!), then we'd have cellular immortality. You could still die from accidents, disease, homicide, but not from ageing. One sentence background info: Telomeres set a count on how many times a cell can divide before it ceases to divide and becoming old and useless; in humans, the count is 40-60 divisions and then you (the cell anyway) dies. Simplified, but that's the essence. Yes, this is all extreme speculation, but if telomeres are the basis of ageing, can you imagine the upside for discovering a "cure" for that? If only someone like Bill Gates or Mark Zuckerberg were willing to throw a billion or $10 billion to answer this question. Ideally it should be government funding it -- like an Apollo moon shot or Manhattan project effort. But any kind of research with words like "immortality" in it will never get off the ground. It has to be funded by an individual or maverick organization.
- krastanov 10y agoOn the contrary, plenty of scientist have had the idea and researched the topic. It is not that easy because immortal cells have the tendency to become cancerous. Before suggesting intellectual dishonesty in all scientists check the first paragraph of the article that says as much.
- cantrevealname 10y agoI didn't accuse anyone of dishonesty. Scientists do say that long telomeres are associated with longer life. But they are very cautious in not saying (at least publicly): Let's see if we can find a way to lengthen or regenerate telomeres and see whether that permits immortal cells and people living hundreds of years.
- Lewton 10y ago"What everyone has thought of, but no scientist is willing to say out loud" What no scientist is willing to say out loud, is basically what scientists have been saying out loud since the mid 90ies. It has nothing to do with unwillingness to talk about the subject, but it has not been pushed that hard because there was* a strong belief that messing with telomeres had a very high risk of causing cancer. *is? Although I think this belief has softened lately
- pfarnsworth 10y agoThis type of thinking is exactly why we are where we are today with Trump. It's not an endorsement to have a conversation, for God's sake. People seem to have forgotten that freedom of speech includes the freedom to sound as stupid as you want. If it's so glaringly obvious to you that it's dumb, then have the confidence that others will find it dumb too. Don't deny people the opportunity to even talk with them because they're interested in what others have to say. You end up driving people underground, which is even more dangerous, like what happened with the Trump supporters, who were too afraid to even talk about the issues that were motivating them.
- sigmar 10y agoYou are conflating minority viewpoints with reputability. No serious media source would invite a conspiracy theorist with no credibility. Differing viewpoints are an important part of any discussion.
- pfarnsworth 10y agoStop changing the subject. The issue that you brought up is whether or not Joe Rogan giving air time to something is endorsing it. Which it isn't. It's having a conversation on a podcast. And why are you comparing Joe Rogan to a "serious media source"? He's a comedian with a podcast, who can talk to whomever he wants that he deems interesting.
- sigmar 10y ago>Stop changing the subject. The issue that you brought up is whether or not Joe Rogan giving air time to something is endorsing it. I was referring to an endorsement of the person, not the topic. ie "Seems irresponsible to give a platform to moon landing truthers."
- nitrogen 10y agoThe concept of "platform" (and thus no-platforming) is an area where IMO ostensibly progressive society has gone off the rails. It starts with good intentions, maybe as a reaction to the silliness of giving equal time to scientists and unqualified critics on mainstream media. But then it morphs into this idea that thinking and talking about an idea, or being seen with people who hold an idea, without foaming at the mouth against it is the same as endorsing it, and that is a very dangerous place to be.
- jondiggsit 10y agoSo quick questions: Is this Elysium Health supplement I'm taking going to give me cancer?!
- arrosenberg 10y agoI've seen those ads. It's pretty unlikely that it will substantially increase your cancer risk. I would also mention that while there is some science behind their claims, the studies they put on their site are insufficient (n=120 people, t=8 weeks of study) to make any medically valid claims, and the efficacy of the treatment (consuming NAD+ and plant sterols) hasn't been clinically proven to have a positive effect on human health. They also don't claim the participants saw a benefit, just that their NAD+ levels were elevated I am personally bullish on the thought process behind NAD+ [1], but I probably wouldn't buy a consumer product for it today without some serious clinical proof. Caveat Emptor. 1 - https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4112140/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4112140/ Disclaimer: I'm involved in the business side of the aging industry, but I only have a BSc in Genetics/Biochem, not a PhD.
- sebringj 10y agoWhat I've read so far of interest relating to age prevention or reversal since I'm a programmer myself and you may find these interesting... A Healthy lifestyle slows telomere length decline by producing more telomerase in your system than otherwise. Activities such as aerobic exercise where you sweat a lot, eating very healthy food, having a bit of red wine now and again and probably most important, having a solid network of people you interact with (and or animals) that care about you and express this for the most part in a positive way. There is also strong evidence that caloric restriction slows your aging process by up to 30% coupled with high nutrition (CRON diet) which is backed up by tons of experiments in animals as seems to be fundamental to our biology. The company "Elysium" produces a drug "Elysium" $50 that claims to slow the aging process through increasing NAD production which we lose through aging, putting you in maintenance mode (similar to CRON?) without having to starve yourself. TA Sciences sells TA-65 and claims to elongate telomeres and reversing aging? by boosting telomerase activity from refining the Astralagus root's enzyme and putting it in pill form (1 part in 10,000 so its 10 times more expensive than Elysium). The other route is gene therapy but it costs 1,000,000 dollars (picture Dr. Evil) which Liz Parrish has partaken in is reported to have increased her telomere length along with a muscle enhancement to avoid sarcopenia. An interesting one is stem cell infusion that I've read about as well as stem-cell injection sites for stem-cell therapy which has been reported to have miracle-like effects in reversing symptoms of stroke to arthritic conditions but I don't know the pricing on this one. Aubry De Grey seems to have tons to say on aging but I have yet to make heads or tails of his conclusions even though he seems to be super smart. David Sinclair is a big proponent of NAD and Sirtuins, having a high degree of credibility in the field and finding proteins that stimulate our production of NAD, seems very sound. I didn't list references as probably something you should look into yourself and more research is coming out so fast to debunk or bunk it.
