A Conservative View on Lifestyle versus Pharmacological Interventions for Aging
This open access commentary reflects a reasonable conservative position on the development of means to treat aging, which is that nothing can yet greater and more reliable results in humans than undertaking a better lifestyle. In this view, some combination of aerobic exercise, strength training, and calorie restriction robustly does more for most people than any of the other options on the table. Ten years ago I would have agreed. Now, however, I think it clear that, at the very least, senolytic therapies to selectively destroy senescent cells and some forms of mesenchymal stem cell transplantation, those capable of produ...

Calorie Restriction and Calorie Restriction Mimetics Dampen Inflammation
Chronic inflammation is an important aspect of aging, a process that stems from low-level biochemical damage and cellular dysfunction, and that then contributes to the progression of age-related disease and tissue dysfunction. Chronic inflammation sustained over years accelerates all of the common fatal age-related conditions: it disrupts tissue maintenance, and leads to fibrosis, immune dysfunction, and many more issues. The chronic inflammation of aging is important enough that beneficial therapies have been built on the basis of suppressing inflammation directly, without addressing its causes. Treatments that actually a...

Notes on the SENS Research Foundation Pitch Day, January 2020
The J.P. Morgan Healthcare conference runs every year in San Francisco, a big draw for the biotech industry, and many organizations take the opportunity to host events at the same time. Among these, the SENS Research Foundation has for the past few years hosted a pitch day in which biotech companies in the longevity industry, largely startups, present to that portion of the Bay Area investor community interested in funding the treatment of aging as a medical condition. I was there to present on progress at Repair Biotechnologies, and took some notes on the other companies as they talked about their work.

Conclusion
A great deal of progress is being made in the matter of treating aging: in advocacy, in funding, in the research and development. It can never be enough, and it can never be fast enough, given the enormous cost in suffering and lost lives. The longevity industry is really only just getting started in the grand scheme of things: it looks vast to those of us who followed the slow, halting progress in aging research that was the state of things a decade or two ago. But it is still tiny compared to the rest of the medical industry, and it remains the case that there is a great deal of work yet to be done at all...

A Look Back at 2019: Progress Towards the Treatment of Aging as a Medical Condition

This study presents the effects of berberine (BBR) on the aging process resulting in a promising extension of lifespan in model organisms. BBR extended the replicative lifespan, improved the morphology, and boosted rejuvenation markers of replicative senescence in human fetal lung diploid fibroblasts. BBR also rescued senescent cells with late population doubling (PD). Furthermore, the senescence-associated β-galactosidase (SA-β-gal)-positive cell rates of late PD cells grown in the BBR-containing medium were ~72% lower than those of control cells, and its morphology resembled that of young cells. Mechanistically, BBR im...

Age-Related Hyperglycemia as a Cause of Increased Cancer Incidence
Why is cancer an age-related condition? One can propose a range of mechanisms: the spread of stochastic DNA damage through cell populations; rising levels of chronic inflammation; ever more senescent cells turning out disruptive, pro-growth signals; the growing inability of the immune system to promptly destroy errant cells. The authors of this open access paper argue that the metabolic dysfunction of later life that leads to raised blood sugar, hyperglycemia, is also an important contributing factor to cancer risk. Most hyperglycemia is self-inflicted via obesity, but it can manifest in other ways as damage and systems fa...

In this study, by adenovirus-mediated delivery and inducible transgenic mouse models, we demonstrate the proliferation of both HCs and SCs by combined Notch1 and Myc activation in in vitro and in vivo inner ear adult mouse models. These proliferating mature SCs and HCs maintain their respective identities. Moreover, when presented with HC induction signals, reprogrammed adult SCs transdifferentiate into HC-like cells both in vitro and in vivo. Finally, our data suggest that regenerated HC-like cells likely possess functional transduction channels and are able to form connections with adult auditory neurons.

Declan Doogan of Juvenescence Presenting at Investing in the Age of Longevity
Investing in the Age of Longevity was an event held in London earlier this year as a part of the Longevity Week, a chance for Jim Mellon and the rest of the Juvenescence team to present their thesis on the longevity industry to the investor community - that this is an enormous opportunity to both greatly improve the human condition and generate returns on investment. A number of companies were there to present, as examples of the work on slowing and reversing aging presently taking place, and I was graciously invited to discuss the latest developments at Repair Biotechnologies. The presentations from the event have been po...

The Prospects for Restoring Neurogenesis in the Aging Brain
Today's open access paper is a review of potential approaches that might be used as a basis for therapies to restore a more youthful level of neurogenesis in the aging mammalian brain. Neurogenesis is the process by which new neurons are created by neural stem cell populations and then integrated into neural networks. In adults, neurogenesis is essential to memory, learning, and the limited degree of regeneration that the brain is capable of enacting. Unfortunately, the supply of new neurons declines with age as the underlying stem cells become ever less active. Beyond making the aging brain more resilient, methods of incr...

Discovering New Mechanisms of Action for Metformin
Metformin is a terrible approach to slowing aging in comparison to, say, mTOR inhibition. Slowing aging in this way, by manipulating the operation of an aged cellular metabolism without repairing the underlying damage that causes aging, is in turn a terrible approach to the treatment of aging. Yet metformin attracts a great deal of interest. I believe that most people simply don't care about effect size and reliability. Most popular science materials don't discuss these points, thus putting every intervention on the same footing in the minds of much of the public. Yet effect size and reliability are the very heart of the m...

Sarcopenia, the progressive loss of muscle mass and strength, is characteristic of aging. A perhaps surprisingly large fraction of the losses can be averted by strength training, but there are nonetheless inexorable proces...

Reporting on the Aging Research and Drug Discovery Meeting Held at BASAL Life 2019
Earlier this year the Aging Research and Drug Discovery meeting was organized as a part of the broader BASAL LIFE scientific conference. As is traditional for such events, the organizers put together a paper reviewing the proceedings. A few of the early highlights are noted below, but many more presentations are briefly discussed in the open access paper. It is a representative selection of the present distribution of projects and research goals in the scientific community focused on intervention in the aging process.
Aging poses profound health-related challenges that need to be tackled to reduce the social and e...
