Happy holidays from the Life Extension Advocacy Foundation! While 2020 has been a trying year in many respects, rejuvenation research has continued throughout, and we are pleased to announce that we have plenty to discuss before we part for the holiday season.
We would like to remind you once again that on January 26-28, 2021, the third annual Longevity Therapeutics Summit will commence! This fully online event will feature more than a hundred leaders in the longevity industry, including researchers and biotech executives, and will discuss ways to target, reverse, and delay the onset of age-related diseases.
Holiday Wishes from Lifespan.io: Keith Comito offers his holiday greetings and discusses the 2019 Annual Report, which features all of our accomplishments from that year.
Oxygen Therapy and Telomeres: The hyperbaric oxygen study, a longevity-focused school for doctors, inflammation and its effects on NAD+, aged blood and old brains, and the Longevity Dialogues featuring Dr. Aubrey de Grey.
Osteoporosis and Alpha-Ketoglutarate: Elevian’s $15 million equity financing, osteoporosis and AKG, a new scaffold for liver regeneration, a gene that protects against the negative effects of obesity, and healthy longevity for all.
Deep Learning Predicts Protein Structure: Deep learning and proteins, CRISPR against cancer, a human trial of resveratrol, protection for insulin-producing cells, and a link between Alzheimer’s disease and gut bacteria.
Reversing Cellular Age in Mice Restores Vision: The restoration of vision through reversing cellular age, a drug that reverses cognitive decline within days, a gene that links diet and longevity, kidney progenitor cells in urine, and the relationship of epigenetics to Alzheimer’s disease.
Biohackers Perform First Plasma Dilution Experiment on Humans: Alexander Fedintsev conducted this plasma dilution experiment, which was similar to the Conboys’ mouse research, on a pair of biohackers in Russia. We interviewed all three of these men about the nature of the experiment and why they underwent it.
Meds and Foods for Kids: In this premiere episode of Lifespan Docs, a new series created by Tim Maupin, Dr. Patricia Wolff talks about the important work she does in helping impoverished kids and what a longer life thanks to science would mean.
This month, we are releasing a video from Ending Age-Related Diseases 2020 on every weekday! Subscribe to our YouTube channel to see even more videos from our annual conference.
Steve Horvath on Epigenetic Clocks: Dr. Horvath discussed the GrimAge epigenetic clock and how it can predict death. Such a clock can be used to evaluate the effectiveness of rejuvenation biotechnology therapies, providing useful clinical endpoints that don’t involve waiting for people to age and die.
Polina Mamoshina on Deep Biomarkers: Deep learning, an advancement over older algorithms of artificial intelligence, has allowed for the useful collection of various data. It allows slightly inaccurate biomarkers to be combined for greater effectiveness.
Alexander Fedintsev on Cross-Linked Collagen: Dr. Fedintsev provides evidence showing that the stiffened extracellular matrix leads to stem cell depletion, cellular senescence, and the failure of neurons to form synapses. Reversing this process could reverse some aspects of aging.
Gabriela Bunu on Longevity Genes: SynergyAge is a database designed to calculate which genes are responsible for longevity, and which genes have been associated with a lack of longevity, in several distinct organisms, including mice.
Judith Campisi on Senescent Cells: Prof. Campisi discussed the effects of senescent cells, including the senescence-associated secretory phenotype (SASP) along with senolytics, the drugs that remove these aged cells.
Alexey Moskalev on Drosophila Genetics: Drosophila is a common subject for aging research, as it is a short-lived insect that shares many of the same aging-related genetic pathways as larger animals, and the genetic effects of certain interventions can be mapped in detail.
Jonathan Clark on Cross-Linked Collagen: This presentation was on the effects of cross-linked collagen on the elastic deformation of our tendons, which connect muscles and bones. The information presented here may be surprising.
Eric Leire on Genflow Biosciences: Genflow is intervening directly in the biology of aging, affecting SIRT6, which, like other sirtuins, is a known regulator of aging. The company intends to develop its SIRT6 plasmid as an epigenomic therapy that will affect downstream hallmarks of aging
Kris Verburgh on Multiple Approaches: Both high-technology and low-technology approaches have their uses in fighting aging, and Dr. Verburgh suggests that we ought to use what we have available right now.
Tyler Gelato on Decentralized Development: Dr. Golato advertises Molecule as a method of fostering collaboration between early developers and pharmaceutical companies in order to bridge the gap between research and business.
Thomas Weldon on Reversing Epigenetic Age: Ponce de Leon Health intends to substantially increase human healthspan by using compounds that are generally recognized as safe (GRAS) as a polytherapy.
Gordan Lauc on Glycans: Dr. Lauc expresses the idea that, as we age, our glycoproteome becomes destabilized and that glycans can be used to return this neglected aspect of aging to a more youthful state.
Michael Geer on Increasing Healthspan: His company, Humanity, intends to allow people to monitor their rates of aging, as doing so can encourage the development of therapies and technologies that prevent age-related diseases.
Paul Spiegel Goes Beyond Retirement: As Mr. Spiegel explains, we may need a new social contract in which radical life extension is given freely in order to remove the problems and expenses posed by pensions and retirement funds and to allow citizens to live happier, consistently productive, and much longer lives.
Sajad Zalzala on a Human Rapamycin Trial: PEARL is a human trial of rapamycin that uses the participation of ordinary people in order to get a large sample size without the expense of a traditional clinical trial.
Reversing Cellular Age in Mice Restores Vision: This month’s Journal Club discusses a paper in which three of the four OSKM reprogramming factors are used to epigenetically reset the cells of mice, allowing them to regain visual function.
Science to Save the World
Blood Transformation: We discuss the various blood types and showcase a new approach to transforming type A positive blood into valuable type O negative blood that can be given to anyone, revolutionizing the blood donation system.
Rejuvenation Roundup Podcast
Ryan O’Shea of Future Grind hosts this month’s podcast, showcasing the events and research discussed here.
Neurological Aging and the Lifespan Limit: Nina Khera returns with information suggesting that our lifespans may be intrinsically limited if we can’t do something about ordinary neurological aging.
David Wood on the Ethics of Anti-Aging: David Wood, chair of the London Futurists, addressed whether or not rejuvenation is scientifically possible, environmental concerns, retirement programs, the effects of rejuvenation on the speed of progress in other fields, and many other ethical questions.
CRISPR Successfully Deployed Against Two Cancer Types: Scientists have successfully tested a new nanoparticle-based delivery system for CRISPR kits, achieving drastic improvements in mouse models of glioblastoma and ovarian cancer.
