REVERSE AGING To Prevent &Treat Diseases 2023 Nov Update
Dr. David Sinclair presents about the new update on epigenetic reprogramming on reversing aging to prevent and treat rare and common diseases in this video.
Genetic mutations that promote reproduction tend to shorten human lifespan, study shows
A University of Michigan-led study based on a review of genetic and health information from more than 276,000 people finds strong support for a decades-old evolutionary theory that sought to explain aging and senescence.
In 1957, evolutionary biologist George Williams proposed that genetic mutations that contribute to aging could be favored by natural selection if they are advantageous early in life in promoting earlier reproduction or the production of more offspring. Williams was an assistant professor at Michigan State University at the time.
Williams’ idea, now known as the antagonistic pleiotropy theory of aging, remains the prevailing evolutionary explanation of senescence, the process of becoming old or aging. While the theory is supported by individual case studies, it has lacked unambiguous genome-wide evidence.
Unlocking the Secrets of Lifespan with Dr. David Sinclair
Welcome to Lifespan with Dr. David Sinclair. Dr. David Sinclair is a professor of genetics and co-director of Harvard Medical School’s Paul F. Glenn Center for Biology of Aging Research.
How to Not Die
Biologist and genetics expert Dr. David Sinclair is out to prove he can live past 100 years old, and he thinks you can too. On this episode Sinclair goes in-depth on the process of aging and the techniques you can incorporate into your life that help you live a longer, healthier life, including optimizing your diet, the benefits of exercise, the role of a positive attitude, the importance of sleep, the three supplements he takes every day, why it’s never too late to slow the process of aging, and so much more.
Study offers new insights into how immune cells recognize their enemies
In order for immune cells to do their job, they need to know against whom they should direct their attack. Research teams at the University of Würzburg have identified new details in this process.
As complicated as their name is, they are important for the human organism in the fight against pathogens and cancer: Vγ9Vδ2 T cells are part of the immune system and, as a subgroup of white blood cells, fight tumor cells and cells infected with pathogens. They recognize their potential victims by their altered cell metabolism.
Research teams from the University of Würzburg and the University Hospital of Würzburg, together with groups in Hamburg, Freiburg, Great Britain and the U.S., have now gained new insights into how these cells manage to look inside the cell. Thomas Herrmann, Professor of Immunogenetics at the Institute of Virology and Immunobiology and his colleague Dr. Mohindar Karunakaran at Julius-Maximilians-Universität Würzburg (JMU), were responsible for the study published in the journal Nature Communications.
Unlocking the Secrets of Aging: Science, Studies, and Interventions for Longer, Healthier Lives
In this episode, Dr. David Sinclair and co-host Matthew LaPlante discuss why we age. In doing so, they discuss organisms that have extreme longevity, the genes that control aging (mTOR, AMPK, Sirtuins), the role of sirtuin proteins as epigenetic regulators of aging, the process of “ex-differentiation” in which cells begin to lose their identity, and how all of this makes up the “Information Theory of Aging”, and the difference between “biological age” and “chronological age” and how we can measure biological age through DNA methylation clocks. #Aging #DavidSinclair #Longevity
