Chinese scientists develop gene therapy which could delay ageing:

BEIJING (Reuters) - Scientists in Beijing have developed a new gene therapy which can reverse some of the effects of ageing in mice and extend their lifespans, findings which may one day contribute to similar treatment for humans.

The method, detailed in a paper in the Science Translational Medicine journal earlier this month, involves inactivating a gene called kat7 which the scientists found to be a key contributor to cellular ageing.

The specific therapy they used and the results were a world first, said co-supervisor of the project Professor Qu Jing, 40, a specialist in ageing and regenerative medicine from the Institute of Zoology at the Chinese Academy of Sciences (CAS).

"These mice show after 6-8 months overall improved appearance and grip strength and most importantly they have extended lifespan for about 25%," Qu said.

[...] Qu said she hopes to be able to test the method on primates next, but it would require a lot of funding and much more research first.

"In the end, we hope that we can find a way to delay ageing even by a very minor percentage...in the future."

        It's actually possible it developed anywhere from Germany, Britain, Canada, the US, or China. The patents documenting each 'unique' facet of CoVid-19 date back up to 22 years, and the samples, research and ownership of the various research passed hands multiple times over the years.

        If CoVid-19 *WASN'T* natural, then the development and weaponization of it was definitely a multinational effort, which leaves us with the question: What else is still in the lab, and are they intended for population control, or as a method to get people taking the vaccines, either for monetization, sterilization, or for testing experimental gene splicing techniques on a population the elites don't care about, failures being documented as a death by the virus or allergic reaction, while getting millions of test cases for say, life extending gene therapies, before the elites consider recieving the treatments themselves?

          While you're searching for explanations, I'll offer a more mundane one.

          Several nations and some corporations were probably researching the COVIDS for their own selfish purposes. No cooperation necessary, it was parallel research. Chinese researchers dropped the ball, and allowed the research to escape the lab. Several articles have been published that strongly suggest, but fall short of proving, this scenario. And, by "strongly suggest", I mean VERY strongly suggest.

          Of course, the Chinese Communist government vehemently denies this scenario, and punishes any journalist or scientist who even talks about it.

        So you think making our already brief lives even shorter could somehow reduce our destructively short-sighted behaviors?
        I'd argue the opposite... the further we can extend life spans, the more people might actually think of the future they'll more likely have to personally deal with. At least a little.
        Also more likely to put off having kids—potentially indefinitely—or choose not to, than already happens anywhere with sane reproductive rights and decent quality of living...
        I'd like to see a full on cure for aging, and suggest that if the whole world had all of the above, we'd all be far better off. I think the cost-benefit to society would actually weigh heavily on the side of preserving knowledge/skills/experience and extending them beyond mortal constraints, and far outweigh saving also on the loss-leading upfront costs of replacement.

          That seems pretty optimistic considering that vanishingly few people make day to day decisions with an eye towards the 5-year impact.

          Long-term thinking is something that has never had significant evolutionary advantage for our species until recently, while immediate gratification has had enormous benefits since before our ancestors evolved a spine.

          Not to mention, any life-extension therapies will almost certainly go primarily to the wealthy and powerful, who are the very ones most responsible for guiding our civilizations on their current destructive paths.

            They are also the few who do make long term plans, it's just that any plan that has current benefits and far future downsides is acceptable to them. By the time they are in their 60's and achieving real power, they only have to put off the consequences for 20 or 30 years. Their descendants will inherit the benefits, the costs go to society in general.
            Give them the opportunity to live to 120 and their plans have to last 50 or 60 years. It is a lot harder to hide negatives for that long.

                To clarify, there is no point going after individuals who created superfund sites in the 1960's. If they were old enough to have that sort of control of a company back then, they are probably dead now, their estates probated, and there is no way to punish or get restitution.

                Letting them live longer means they either have to do a better job in the first place, or hide it for much longer. Hiding toxic waste for twenty years is easy. Put it in drums and bury it, they take that long to rust out. Hiding it for 60 years is much harder, it is probably easier to dispose of it properly.

                Similarly for most problems, indefinitely putting off the consequences is pretty damn close to "sustainable".

                  Okay, I can see where you're coming from for minor "one off" criminal issues, just not the systemic issues that are the major problem.

                  Even then - there's still everyone who participated without blowing the whistle we could go after - it wasn't the executives who barrelled and buried the waste. Not to mention the estates of the executives who made the call. Knowing that your children would suffer because of your crimes would be some deterrent. Perhaps not much of one, but I see no reason to let those who profited from your crimes keep the profit when they're discovered. And if the executive is only very old, let them die in prison or on the streets.

                  The reality though is that even when these sorts of things are caught quickly, the corporation gets a fine, and the executives *maybe* get a slap on the wrist. Hardly a disincentive.

        Lower fertility yes, but after the counterrevolutionaries have been purged, we will be able to much more rapidly mobilize a response to AGW. There will be no need to artificially limit lifespans, especially with easy, confidential access to abortion and free birth control pills provided by our one world government-owned and operated healthcare system.

    Back in the late 70s/early 80s as a college student I had to write a term paper on something. I chose aging. The latest Omni magazine had an article on it and I quoted it heavily. I, as a young 20 something, figured organ transplants and gene therapy would have people like me (e.g. early 20s) living to 150 years and beyond.

    I lost that paper during a move but wish I still had it to re-read (it was titled Never Say Die, after Black Sabbath's newest album). I remember 2 things about it:

    1) Teacher said I got bumped up a grade because it was printed on an Epson MX-80, not handwritten (I got that a lot at the time)
    2) It was forward thinking.

    I got an A on it.

    / same class, wrote another paper on how to make a bomb
    // described dissolving styrofoam in gasoline to make a poor man's napalm, amongst other stuff. Chemistry classes for the win.
    /// got an A on that one too, if memory serves "disturbing content, but readable", readable due to my Epson MX-80 printer.

      Who would want to live longer on this accursed planet?

      The ones who want to live longer are the ones who know that whatever happens they have the money and power to protect themselves from everything else on this accursed planet.

      You know who they are. The ones who have the money to keep all the negative impacts of the current world situation from effecting them. You know the ones I'm talking about, the ones who have a winter/summer homes. They can afford to move them at the drop of a hat. Or just get a huge boat so the can live near the coast and not worry about rising sea levels and winter storms (head to where it's summer) The ones who don't have to worry about how much their food/utils/rent costs them because at the end of the day they STILL have more money than they had in the morning. And they can afford to get the best medical care available, including the cosmetic options so the don't show their real ages.

      And when it really gets too bad here on Earth they can always go to Mars, because they can afford it.

    As far as I'm aware, kat7 makes an enzyme that's needed for DNA replication. That is all the gene does - makes proteins that make this enzyme.

    So, if this enzyme is an issue, why do we need gene therapy or crispr or any of that. We can pop a pill to destroy the enzyme. He have many pills like that - for example to prevent hair loss (finasteride), and to force people quit booze (disulfiram).

    So this sounds like complete crap to me. So I googled it. Yep, complete crap.
    https://jlb.onlinelibrary.wiley.com/doi/full/10.1189/jlb.1MA0816-338R [wiley.com]

    so this enzyme is indeed needed for cell replication, and some cells - like your immune system - don't survive without it.

    so, let's put conspiracy hats on. here's a gene that makes an enzyme. but instead of a daily pill to kill the enzyme (not permanent), we have gene therapy (permanent) to do it. in tests removing this enzyme, the patien's tcells and bcells didn't develop normaly. So, this gives you AIDS.

    Thanks Chinese dude.
