A Natural Senolytic
In this perspective, it has been undisputingly shown that fisetin reduced the level of these damaged cells in the body. They found this first by treating mice towards the end of life with this compound. The improvement in health and lifespan were remarkable. (Source) The paper, “Fisetin is a senotherapeutic that extends health and lifespan,” was recently published in EBioMedicine. (3)
“These results suggest that we can extend the period of health, termed healthspan, even towards the end of life,” said Robbins, one of the lead scientist. “But there are still many questions to address, including the right dosage, for example.” (ibid)
One of the key hurdles that these researchers surmounted was to target only the senescent cells. Under the guidance of Edgar Arriaga, a professor in the Department of Chemistry in the College of Science and Engineering at the University of Minnesota, the team used mass cytometry, or CyTOF, technology and applied it for the first time in aging research, which is unique to the University of Minnesota.
“In addition to showing that the drug works, this is the first demonstration that shows the effects of the drug on specific subsets of these damaged cells within a given tissue.” Robbins said. (Ibid)
A Natural Anti-Cancer Agent
As the Institute has shown with other natural compounds, Fisetin can also modulate other disease pathways in the direction of restoration and homeostasis. In this perspective, Fisetin was shown to inhibis various attributes of angiogenesis in vitro and in vivo, that which has significant implications for angioprevention and even anti-cancer angio-treatment. Carcinogenesis 2012 33(2):385 – 393. (4) Flavonoids like fisetin are well documented to be restorative. (5)
Discussion & Conclusion
Isolating a molecule from whole fruits and vegetables, synthesizing it in the lab, finding the right therapeutic dosage and testing it in animals and then humans is the conventional way of carrying out the business of science. However, the experience of the Optimal Longevity Institute shows that using fruits and vegetables that are rich in fistin, in combination with other natural senolytics and advanced immunotherapy has the potential to be decisive insofar as both cancer and longevity are concerned. Human clinical trials are therefore warrented.
