Outlining Some of the Science Behind Partial Reprogramming at Turn.bio
Turn.bio is an early venture in the new field of in vivo cellular reprogramming, though it is unclear as to whether the partial reprogramming approach they are taking will eventually be used directly in patients, versus in cell cultures prior to transplantation for cell therapy. The publicity materials here cover some of the work undertaken by one of the scientific founders of Turn.bio in recent years, including the transplantation of partially reprogrammed muscle cells into old mice to restore muscle function.
Cells can be reprogrammed into pluripotent stem cells via expression of a small number of genes - the Yama...

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...

The Wrong Inflection Point in Aging Research
While it is still a small field in comparison to much of biotechnology and medicine, research into slowing and reversing the aging process has achieved legitimacy and growth in the past decade. This newfound capacity for progress results from a great deal of work by patient advocates, visionary researchers, and other allies to overcome public disinterest and a hostile leadership in the field of gerontology.
Sadly, most participants in the now energized research and development communities are pursuing varieties of a poor strategy, often called geroscience. They have taken the wrong realization regarding the plastici...

In this study, we intravenously administrated the young mitochondria into aged mice to evaluate whether energy production increase in aged tissues or age-related behaviors improved after the mitochondrial transplantation. The results showed that heterozygous mitochondrial DNA of both aged and young mouse coexisted in tissues of aged mice after mitochondrial administration, and meanwhile, ATP content in tissues increased while reactive oxygen species (ROS) level reduced. Besides, the mitotherapy significantly improved cognitive and motor performance of aged mice. Our study, at the first report in aged animals, not only prov...

A Popular Science Overview of the Development of Senolytic Therapies
This popular science article is a decent introduction to the still young field of senolytic therapies to selectively destroy senescent cells in aged tissues. That said, the author fails to note any of the numerous senolytic programs other than those of the Mayo Clinic and Unity Biotechnology - which represent an increasingly small portion of the field as a whole. The accumulation of lingering senescent cells is one of the contributing causes of aging; these errant cells secrete a potent mix of signals that spur chronic inflammation, change cellular behavior for the worse, and destructively remodel tissue structure. Senolyt...

An Update from the Methuselah Foundation on Progress at Methuselah Fund Portfolio Companies
The Methuselah Foundation is one of the oldest of the present generation of organizations focused on advancing human rejuvenation, founded more than 15 years ago. At that time there was none of the present enthusiasm for treating aging as a medical condition, and indeed the concept was mocked outside the scientific community and actively discouraged within research circles by leading scientists in the field of gerontology. The Methuselah Foundation and its network of allies are a large part of the reason why things have changed: it took a great deal of work to change this dismissive culture into one that saw and embraced t...

Trammpolin, A Meniscus Prosthesis to Improve Knee Surgeries: Interview with CEO Jan Hunik
Meniscus tears are a fairly common knee injury. Treatment typically involves complete or partial removal of the damaged meniscus. Without shock-absorbing role of the meniscus, however, patients are at risk for accelerated wear of the knee joint and osteoarthritis. Currently, patients have to wait for many years until they are eligible for a total knee replacement (TKR). Orthopedic surgeons lack options during this period, what they call the “treatment gap.”
ATRO Medical is working on another option for patients: a meniscus prosthesis. The Netherlands-based company was founded in 2016 and has been developing the Tram...

Notes on the 2020 Longevity Therapeutics Conference in San Francisco
I recently attended the 2020 Longevity Therapeutics conference in San Francisco. I presented on the work ongoing at Repair Biotechnologies, but as is usually the case the more important parts of the visit took place outside the bounds of the conference proper. Longevity Therapeutics is one of the four or five core conferences for the longevity industry, at which you'll meet many of the early participants - a mix of scientists, entrepreneurs, and investors, and patient advocates. As such, most of the conference goers have already seen my updates, or are otherwise aware of the Repair Biotechnologies programs aimed at thymic ...

In conclusion, this study suggests that epigenetic age acceleration is significantly associated with lung function in women older than 50 years. We hypothesised that this could be due to menopause. However, we have observed that menopause has minimal effect and therefore there is possibility of other unknown physiological factors at older age in females mediating the epigenetic age acceleration effect on lung function. While, it is still unknown what exactly epigenetic aging from DNA methylation measures, this study suggests it can be utilised as one of the important factors to assess women's lung health in old age. DNA me...

Combination Gene Therapy for α-Klotho and TGFβR2 Improves Osteoarthritis in Mice
Researchers here report that upregulation of α-Klotho and TGFβR2 together, via gene therapy, can modestly reverse osteoarthritis in a rat model in which untreated animals progress to a more severe stage of the condition. Inhibiting TGF-β receptors such as TGFβR2 is known to suppress chronic inflammation, and likely functions by interfering in the inflammatory TGF-β signaling produced by senescent cells. The evidence for cellular senescence to drive the progression of osteoarthritis is quite compelling at this point. Meanwhile, α-Klotho declines with age and upregulation of this protein is known to improve regenerativ...

In this study, we investigated the link between AF and senescence markers through the assessment of protein expression in the tissue lysates of human appendages from patients in AF, including paroxysmal (PAF) or permanent AF (PmAF), and in sinus rhythm (SR). The major findings of the study indicated that the progression of AF is strongly related to the human atrial senescence burden as determined by p53 and p16 expression. The stepwise increase of senescence (p53, p16), prothrombotic (TF), and proremodeling (MMP-9) markers observed in the right atrial appendages of patients in SR, PAF, and PmAF points toward multiple inter...

Reviewing the Relationship Between TGF- β and Cellular Senescence
A rising level of TGF-β has long been associated with numerous aspects of aging. More modern research has shown it to encourage cells to become senescent. Further, TGF-β is an important component of the inflammatory mix of signals secreted by senescent cells, making it a part of the mechanism by which senescent cells can encourage their neighbors to also become senescent. When senescent cells fail to clear quickly, as happens in older individuals, this leads to a feedback loop of continually rising chronic inflammation and ever greater numbers of senescent cells. This is an important contribution to degenerative aging an...

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...
