'Supermodel Granny' Drug Extends Life In Mice By 25%, Study Finds 95

A drug has been shown to extend the lifespan of laboratory mice by nearly 25%, with treated mice displaying fewer cancers and improved health and strength. It earned them the nickname "supermodel grannies" due to their youthful appearance. "The drug is already being tested in people, but whether it would have the same anti-ageing effect is unknown," reports the BBC. From the report: The team at the MRC Laboratory of Medical Science, Imperial College London and Duke-NUS Medical School in Singapore were investigating a protein called interleukin-11. Levels of it increase in the human body as we get older, it contributes to higher levels of inflammation, and the researchers say it flips several biological switches that control the pace of ageing.

The researchers performed two experiments. The first genetically engineered mice so they were unable to produce interleukin-11. The second waited until mice were 75 weeks old (roughly equivalent to a 55-year-old person) and then regularly gave them a drug to purge interleukin-11 from their bodies. The results, published in the journal Nature, showed lifespans were increased by 20-25% depending on the experiment and sex of the mice.

Old laboratory mice often die from cancer, however, the mice lacking interleukin-11 had far lower levels of the disease. And they showed improved muscle function, were leaner, had healthier fur and scored better on many measures of frailty.

    Why would we want longer living mice with improved health and strengtth? Are they trying to make a new end boss? Imagine an entire colony of these new and improved mice coming out of the walls of a small room you're in.

      Rather than living longer, I'd rather have better quality of life with the time I have.

      A study recently reported that a beer a week can take a couple of months off your lifespan. Seems like a very good deal to me.

          And that's the part that I find fascinating about those type of studies. They are utter bullshit when they try to quantify your likely death based on how many cigarettes, beer, exercise or (fill in the blank) you have partaken on.

          Life is too short to spend all our time trying to squeeze out a few extra years. All of those years an the old and deteriorated end for that matter.

              Agreed. It's all well and good to talk with ease about going to oblivion when ones health is good, most dont seem to hold the same opinions though when they are dying or if they do it's often because they've destroyed their bodies via poor living and thus have nothing to live for.

              After years of poor living those in poor health are rarely ready to go when death comes knocking early though.

                  Absolutely people arent 100% responsible for their infirmities, I was never arguing that point. Given the poor way most are treating their bodies in this country though https://www.cdc.gov/obesity/ph...

But the other thing you mention is the tough one: you don't have control over everything. So if dying 'young' isn't in the cards anymore, not as much sense to 'live lo

              Oh, I do get the sentiment. We're all involved in life based on our temperament and experiences. A friend of my wife's brother was dying of terminal cancer. He was in a lot of pain, but he held on long after there wasn't much point, as the cancer eventually entered his bones. At that point, it is damn hard to manage pain. But he wouldn't let go until he more or less just rotted. To me, his will to live was strong, but over broad. Bedridden and in pain, and doing nothing but lying in bed, I guess he found t

        So much this. The problems with "life extension" is that if and when it works, all of the extension is on the old end of life.

        If I had, say, another 20 years on my 30's, then return to normal aging - yeah - sign me up. If all life extension gets me is more years of being old - miss me with that.

          people say this when they are young... my 89 year old mom though, she is enjoying her life, still working as a lawyer (doing care and protection for the State and helping people, believe it or not). I am pretty sure she doesn't want to die soon simply because of her age and current state of decrepitude... I mean she has serious scoliosis which she never got treated when she was younger, and now they say she isn't really a candidate for treatment, so she is a hunchback, with her spine twisted up and still happy to get up every single day and get out there and fight the good fight defending people who have been deemed unable to defend themselves.

          At a younger age it is easy to believe that all old people are this or that, but once you hit old age, well, people are all different and all old people don't spend the last years of their lives in care and unable to do things that they enjoy.

          This is not to say that I want you to do x or y, no I just hope that you live to a ripe old age and also enjoy every minute of it, dying with a smile on your facw, as you fight the Grim Reaper every step of the way.

        the summary clearly states that reduced inflammatory stuff, better strength and better appearance were some of the side effects... hence that sounds like a better quality of life to me. Currently I suffer from too many things causing joint inflammation, so reducing that would definitely help me and my quality of life!

            That misinterpretation says a lot more about you than about me. And it has nothing to do with self-preservation. Competent self-preservation takes cost of measures vs. quality of outcome into account. Otherwise you could live as lot longer and be miserable along the way. I fail to see how that is desirable.

            I am scared to death of dying....I know it's coming, but I'm more than willing to do anything possible to push it as far off as humanly possible.

          Wtf are you even talking about here? People are afraid of dying because odds are it's the end of their consciousness, as in they will no longer exist. Unless your life is utter shit any rational person would chose life over death hence people working to preserve their health.

            What odds? You should not listen to religions like Physicalism. Incidentally, fear is always a bad advisor. Even if death of the physical body is the end of consciousness (which we do not know and there are some pretty good indicators it may not be), so what? Living in fear is living badly.

      While all this is true, given that it manages to improve the health of even just 36 months old animals, if it has the same effect on humans, it might simply mean a healthier 60s, maybe 70s. That's not bad at all - not everyone dies of PFAS/plastic build-up, or similar. So, assuming the result can be replicated in humans, it is a positive news.

    • So the drug will give us 9 months longer to live!
      People would pay that... and for many years since they don't know when they'd die. The irony would be if they died sooner because it does more harm after 12 months of taking it!

      It's really simple to assume it will extend humans by 25%. Now if the drug could reverse dementia... keep it away from Trump, I'm enjoying watching his decline; I'm seeing how long it takes before his supporters catch on.
