The topic for the December Journal Club was the recently published paper Fisetin is a senotherapeutic that extends health and lifespan. This commonly available supplement, a plant-based polyphenol, appears to influence aging in mice by clearing senescent cells, which are one of the hallmarks of aging.

There is certainly plenty of justification for moving this compound to human trials where reliable data can be recorded and to see if the effects observed in mice and human cell lines are seen in people. We discuss how running human studies offers low-hanging fruit and could be reasonably easy and safe to do given its superb safety profile.

If you would like to take a look at the data yourself, you can find the open access paper here.

    Thank you for these interesting prospects !
    What do you think the results of using Fisetin will be on fitness and health for an average fit 60 years old person ?

      Yea, I’d like to know the answer to this question as well since I will be 60 at end of year also.

    Post a list of research projects that would be good to work on.

    After reading a number of articles on fisetin, I am very optimistic about it’s translation to human health. I’m currently doing some more digging to see what would be a good dose, along with an appropriate carrier, for human testing. I think that a high enough dose mixed with a carrier that ensures optimal bioavailability, ie. blood delivery, taken for a relatively short length of time should have measurably beneficial effects if everything that has been published regarding animal trials is directly translatable. The extremely low toxicity of the compound, with no acute toxicities noted , and that people have been taking lower doses as supplements for long periods of time with no ill effects that I am aware of bodes very well for a much higher dosage trial. Either it will work or it won’t.

      It could be the low hanging fruit as we talked about last Journal Club I hope the data for it comes out soon. Scripps published D&Q data late last year too I will send the paper over, its an n=14 human study.
