Forever Healthy Foundation Publishes a Risk-Benefit Analysis of Dasatinib and Quercetin as a Senolytic Therapy
The Forever Healthy Foundation publishes a series of conservative risk-benefit analyses of presently available interventions that might prove beneficial in addressing aspects of aging. These range widely in proven effectiveness, quality of animal evidence, and theoretical utility. Some do not in any way attack the known root causes of aging. Some are still pending any sort of rigorous human trial data. Some have plenty of human data that strongly indicates small, unreliable effects at best. It is nonetheless a useful exercise to make clear which are which. In a world in which the "anti-aging" industry propagates all sorts ...

In conclusion, our results suggest a previously unknown mechanism whereby the canonical NF-κB cascade and a mitochondrial fission pathway interdependently regulate endothelial inflammation. Lin28 as a Target for Nerve Regeneration https://www.fightaging.org/archives/2020/05/lin28-as-a-target-for-nerve-regeneration/ Researchers here show that the gene Lin28 regulates axon regrowth. In mice, raised levels of Lin28 produce greater regeneration of nerve injuries. Past research has investigated Lin28 from the standpoint of producing a more general improvement in regenerative capacity. It improves mitochondr...

The Latest on Hyaluronan in Naked Mole-Rat Longevity
Naked mole-rats live nine times as long as similarly sized rodents, and are near immune to cancer. Researchers have for some years investigated the biochemistry of this species, in search of mechanisms that might be applied to improve health and longevity in other mammals, or form the basis for cancer therapies. Teams have looked into many different areas: mitochondrial function; better DNA repair; a greatly attenuated senescence-associated secretory phenotype; more efficient operation of cancer-suppression genes; and a heavier form of hyaluronan. Researchers here show that this heavier form of hyaluronan is protective of ...

On Nutraceutical Senolytics
Nutraceuticals are compounds derived from foods, usually plants. In principle one can find useful therapies in the natural world, taking the approach of identifying interesting molecules and refining them to a greater potency than naturally occurs in order to produce a usefully large therapeutic effect. Unfortunately, in practice the nutraceutical industry is a largely a lazy one, in which entrepreneurs take advantage of a short path to market, and a lack of interest among consumers in whether or not products actually work, in order to repackage cheap ingredients into expensive brands that have minimal, unreliable, or even...

This study is par for the course, looking at Japanese Olympic participants. Interestingly, it hints at the upper end of the dose-response curve for physical activity, in that a longer career as a professional athlete may be detrimental in comparison to lesser degrees of exercise and training. From this large, retrospective cohort study targeting 3546 Japanese Olympic athletes, we observed significant lower mortality among Olympians compared with the Japanese general population. The overall standardised mortality ratio (SMR) was 0.29. The results were consistent with previous studies conducted in other non-Asian co...

A TAT Peptide Based Approach to Upregulation of Proteasomal Activity
The proteasome is a construct in cells that shreds damaged, misfolded, or unwanted proteins, reducing them to component parts that can be reused. It is a part of the ubuiquitin-proteasome system: molecules to be destroyed are tagged with ubiquitin, and drawn into a proteasome for recycling. Greater proteasome activity is thought to be a good thing, improving cell function. This is of particular relevance to aging, as proteasomal function declines with age, contributing to faltering cell and tissue function, particularly in the long-lived cells of the nervous system. While established drugs exist to inhibit activity ...

This study delves into the mechanisms by which a short period of fasting can accelerate wound healing. Fasting triggers many of the same cellular stress responses, such as upregulated autophagy, as occur during the practice of calorie restriction. It isn't exactly the same, however, so it is always worth asking whether any specific biochemistry observed in either case does in fact occur in both situations. In particular, the period of refeeding following fasting appears to have beneficial effects that are distinct from those that occur while food is restricted. Multiple forms of therapeutic fasting have been repor...

“ Essential Oncology ” : The COVID Challenge
By CHADI NABHAN MD, MBA, FACP One harsh Chicago winter, I remember calling a patient to cancel his appointment because we had deemed it too risky for patients to come in for routine visits—a major snowstorm made us rethink all non-essential appointments. Mr. Z was scheduled for his 3-month follow-up for an aggressive brain lymphoma that was diagnosed the prior year, during which he endured several rounds of intense chemotherapy. His discontent in hearing that his appointment was canceled was palpable; he confessed that he was very much looking forward to the visit so that he could greet the nurses, front-desk staff, ...

Impaired Autophagy in the Aging of Stem Cell Populations
The cellular housekeeping mechanisms of autophagy act to recycle proteins and structures within the cell. Upregulation of autophagy appears to be a crucial part of the reason why the response to mild stresses - such as heat, cold, lack of nutrients, and toxins - can actually improve cell and tissue function. Certainly the practice of calorie restriction relies upon functional autophagy in order to extend healthy life span. Researchers here note that autophagy is important in the maintenance of the many stem cell populations throughout the body that are required for ongoing tissue maintenance. The characteristic impairment ...

We report a new class of natural-product-inspired covalent inhibitors of telomerase that target the catalytic active site. Age-Related Epigenetic Changes that Suppress Mitochondrial Function https://www.fightaging.org/archives/2020/03/age-related-epigenetic-changes-that-suppress-mitochondrial-function/ Today's open access research reports on two specific epigenetic changes observed in old individuals that act to reduce mitochondrial function. This joins an existing list of genes for which expression changes are known to impact mitochondrial function with age. A herd of hundreds of mitochondria are found...

In conclusion, the recently demonstrated protective effects of NMN treatment on neurovascular function can be attributed to multifaceted sirtuin-mediated anti-aging changes in the neurovascular transcriptome. Our present findings taken together with the results of recent studies using mitochondria-targeted interventions suggest that mitochondrial rejuvenation is a critical mechanism to restore neurovascular health and improve cerebral blood flow in aging.

USP7 Inhibition Clears Up to Half of Irradiation Induced Senescent Cells From Mouse Tissues
Researchers here report on the discovery of a novel mechanism by which senescent cells can be selectively destroyed. Short-term senolytic treatments to date seem to cluster tightly into two categories: (a) largely ineffective, and (b) able to destroy between 25-50% of senescent cells in tissues. Few have achieved greater clearance so far, and few lie in between these two outcomes. In the present environment, of ample seed stage funding and enthusiasm for targeting senescent cells as a treatment for aging, it seems likely that someone will pick up this new approach for clinical development in the near future. Altho...
